The best gravel bike accessories depend on whether you need practical storage, better visibility, or tools for roadside repairs. My best overall pick is the Crankbrothers M 19 for its broad repair utility, while the Topeak Aero Wedge Pack is a strong choice for compact, expandable saddle storage and the JXFUKAL 9.5L Rack Bag suits riders carrying more gear. The main tradeoff is between keeping a bike light and adding capacity or convenience for longer rides. Fit, weather protection, and compatibility matter as much as the feature list.

Key Takeaways
The Crankbrothers M 19 leads for repair readiness: unlike bags and visibility add-ons, it directly addresses the need to handle common mechanical issues away from home.
Storage choices serve different ride lengths: the Topeak Aero Wedge Pack is compact and expandable, while the JXFUKAL 9.5L Rack Bag is aimed at carrying substantially more gear.
Phone-access bags trade convenience for fit concerns: several frame bags add a phone holder, but riders should check frame shape, screen access, and interference before choosing one.
Water resistance is not the same as full waterproofing: this roundup includes both waterproof-labeled bags and a water-resistant option, so sensitive items may still need an inner dry pouch.
Small accessories can solve specific problems: the Ass Savers Mudder Mini targets spray, the mirrors improve rearward visibility, and the Suruid cages add bottle capacity without requiring a large bag.

More Details on Our Top Picks
Topeak Aero Wedge Pack Medium Expandable Bike Seat Bag
The Topeak Aero Wedge Pack is my pick for riders who want trail-repair essentials tucked behind the saddle, with room to expand when a ride calls for an extra item. Its 0.98–1.31-liter capacity suits a tube, tools, and small accessories, while the quick-release straps make it easier to remove than a bag that stays fixed to the bike. Compared with the Rhinowalk Bicycle Handlebar Bag, it keeps storage off the bars and is better suited to a compact repair kit than items you want close at hand.
The tradeoff is its single, soft-sided compartment: gear has little internal separation or structure, and the capacity is modest for longer trips. The reflective strip and rear light clip add useful visibility details, but riders who want a phone window or more accessible storage should look elsewhere.
Pros:- Expandable capacity accommodates a small ride kit with some extra room when needed.
- Quick-release strap mounting makes it convenient to remove from the saddle.
- Reflective strip and rear light clip support visibility from behind.
- Compact saddle position leaves handlebar space available for other gear.
Cons:- One compartment provides no separation between tools and other contents.
- Soft shell offers limited structure and protection for delicate items.
- Maximum capacity is modest for riders carrying gear for long or remote rides.
Best for: Gravel riders who want a removable saddle-mounted kit for a spare tube, compact tools, and other ride essentials.
Not ideal for: Riders carrying bulky or organized loads, or anyone whose saddle lacks rails for the mounting straps.
- Capacity:0.98–1.31 liters
- Mounting:Seat mount with removable straps
- Compatibility:Railed bicycle saddles
- Dimensions:7.9 × 4.7 × 4.3 in
- Weight:130 g
- Material:Nylon
- Visibility:3M reflective strip and rear safety light clip
- Warranty:2 years
Our verdict“Choose the Topeak for a compact, expandable saddle kit, but pick a larger handlebar or frame bag for more accessible, higher-capacity storage.”
Granite Juicy Nipple Presta Valve Core Remover Caps, Oil Slick
The Granite Juicy Nipple caps earn a place in a gravel kit by making a small part of tire maintenance do double duty: each cap works as both a dust cap and valve-core remover. That can be useful for riders who carry tubeless supplies and want the core tool available without adding another loose item. At just 2.5 g for the pair, they add almost no bulk beside a larger repair tool such as the Crankbrothers M 19.
They are a narrow-purpose accessory, not a substitute for a multi-tool or full tire-repair kit. Their fit is limited to Presta valves, and riders with no need to remove valve cores may gain little from the added function. The anodized aluminum and knurled finish support grip and easy handling, but these caps cannot solve broader trailside mechanical problems.
Pros:- Combines a valve-core remover with a protective dust cap.
- Lightweight aluminum construction adds very little weight.
- Knurled finish helps with installation and removal.
- Pair provides caps for two Presta valves.
Cons:- Compatible only with Presta valves.
- Limited to valve-cap and core-removal tasks, unlike the Crankbrothers M 19 multi-tool.
- Small size can make the caps easy to misplace when removed.
Best for: Gravel riders running Presta valves who carry tubeless repair supplies and want a valve-core tool kept on the bike.
Not ideal for: Riders using Schrader valves or those seeking a versatile repair accessory rather than a valve-specific tool.
- Material:6061 aluminum
- Compatibility:Bicycle Presta valves
- Fit:Universal
- Number of pieces:2
- Weight:2.5 g
- Diameter:6.1 mm
- Finish:Anodized, knurled
- Color:Oil Slick
Our verdict“Choose these caps if your gravel bike uses Presta valves and you want a valve-core tool always on hand, not as a replacement for a general repair tool.”
Crankbrothers M 19 Bike Multi-Tool, Matte Black
The Crankbrothers M 19 is the most repair-focused pick in this group. Its 19 tools cover common adjustments, including multiple hex and Torx sizes, spoke wrenches, and a chain tool compatible with 8- through 12-speed drivetrains. That breadth makes it a more useful companion for remote gravel rides than the Granite Juicy Nipple caps, which address only Presta valve-core removal.
The compact 89 mm body and side grips are practical when a repair calls for leverage or handling with gloves. The tradeoff is 175 g: riders prioritizing the lightest possible kit may prefer fewer tools, and carrying a multi-tool does not remove the need for bike-specific spares or tire supplies. Its broad coverage makes sense for self-sufficient riders, while casual outings close to home may not call for this much equipment.
Pros:- Nineteen tools cover a wide range of common trailside adjustments.
- Chain tool supports 8-, 9-, 10-, 11-, and 12-speed chains.
- Side grips offer a more secure hold, including when wearing gloves.
- Chromium-molybdenum steel construction and lifetime warranty support long-term ownership.
Cons:- At 175 g, it weighs more than a minimal tool for short rides.
- A compact multi-tool can be less comfortable than full-size tools for stubborn repairs.
- Does not replace tire-repair supplies or bike-specific spares.
Best for: Gravel riders who travel beyond easy roadside assistance and want one compact tool for common adjustments and chain repairs.
Not ideal for: Weight-conscious riders who carry only a minimal emergency kit or cyclists who rarely perform their own repairs.
- Number of tools:19
- Hex wrenches:2, 2.5, 3, 4, 5, 6, and 8 mm
- Open wrenches:8 mm and 10 mm
- Spoke wrenches:#0, #1, #2, and #3
- Screwdrivers:Phillips #1 and #2; flat #2
- Torx:T-10 and T-25
- Chain tool compatibility:8-, 9-, 10-, 11-, and 12-speed
- Length and weight:89 mm; 175 g
- Material and warranty:Chromium-molybdenum steel; lifetime warranty
Our verdict“Pick the M 19 if repair coverage matters more than shaving weight from your gravel kit.”
Rhinowalk Bicycle Handlebar Bag, 2.4 L
The Rhinowalk Bicycle Handlebar Bag is a practical choice when you want snacks and small essentials within reach instead of packed behind the saddle. Its 2.4-liter capacity offers more accessible volume than the Topeak Aero Wedge Pack, and removable straps let the bag come off the bike to carry as a shoulder bag. External elastic cords add a place for items that need quick access, while reflective strips help with visibility.
This is still a compact, single-compartment bag, so it will not replace a larger rack or frame setup for bulky touring loads. The waterproof zipper helps protect contents, but the product data does not describe the whole bag as fully waterproof. Strap length may also need trimming to suit some handlebars, making fit less straightforward than a purpose-shaped fixed mount.
Pros:- Handlebar placement keeps small essentials easy to reach while riding.
- Removable straps let the bag double as a shoulder bag.
- External elastic cords provide additional carry space.
- Reflective strips and a waterproof zipper add practical features for changing conditions.
Cons:- The 2.4-liter capacity limits use for bulky or extended-trip loads.
- Single compartment offers little separation for small items.
- Strap length may need trimming to fit some handlebars.
Best for: Day riders who want snacks, a phone, or small personal items accessible from the bars and useful off the bike.
Not ideal for: Bikepackers carrying a large load or riders who need confirmed full-bag waterproof protection and multiple compartments.
- Capacity:2.4 L
- Dimensions:9.6 × 3.9 × 3.9 in
- Weight:160 g
- Material:Polyester
- Mounting:Handlebar
- Straps:Three removable Velcro straps
- Closure and water resistance:Zipper with waterproof zipper design
- Carry and visibility features:Shoulder-bag carry; reflective strips
Our verdict“Choose this bag for accessible day-ride storage and off-bike carry, but select a larger option for substantial bikepacking loads.”
Whale Fall Waterproof Bike Frame Bag with Phone Holder
The Whale Fall frame bag stands apart from the Topeak saddle pack and Rhinowalk handlebar bag by combining one liter of storage with a phone window. Its touchscreen-compatible TPU panel and sun visor put navigation where a rider can see it, while the hard EVA body, sealed zipper, and included rain cover add layers of weather protection for the contents. Adjustable straps make it a flexible fit for many frames without tools.
The phone-first layout comes with compromises: storage is limited, and compatibility tops out at phones up to 7 inches. Riders who need room for a larger repair kit will get more capacity from the Rhinowalk bag, though they give up the dedicated phone window. Check frame clearance and device dimensions before choosing; a fit that works on one bike or phone may not work on another.
Pros:- Touchscreen-compatible phone window supports on-bike navigation access.
- Hard EVA body, sealed zipper, and included rain cover help protect contents.
- Sun visor can improve screen visibility in bright conditions.
- Adjustable straps attach without tools and fit most bike frames.
Cons:- One-liter capacity leaves limited room for other ride gear.
- Phone compatibility is limited to devices up to 7 inches.
- Frame fit and clearance can vary between bikes.
Best for: Navigation-focused gravel riders with a compatible phone who want it visible and protected alongside a small set of essentials.
Not ideal for: Riders carrying a larger repair kit, using a phone over 7 inches, or whose frame geometry leaves little mounting clearance.
- Capacity:1 liter
- Material:Ethylene vinyl acetate (EVA)
- Dimensions:7.48 × 3.94 × 3.94 in
- Weight:5.3 oz
- Phone compatibility:Phones up to 7 inches
- Mounting:Frame mount with adjustable straps
- Closure and water resistance:Zipper; waterproof design
- Included accessory:Rain cover
- Phone feature:Touchscreen-compatible TPU window with sun visor
Our verdict“Choose the Whale Fall if visible phone navigation and weather protection matter more than carrying a larger load.”
Ass Savers Mudder Mini Bicycle Mudguard
I’d choose the Ass Savers Mudder Mini for gravel riders who want to reduce grit hitting their face and headset bearings without adding a full-size fender. At just 21 g, it adds little weight, and its strap-on fit works with cross and gravel forks for tires from 32–55 mm. Compared with the ROCKBROS Waterproof Bicycle Frame Phone Bag, which helps carry gear, this accessory addresses a different ride problem: spray reaching the rider and fork area.
The tradeoff is its limited coverage: it does not block general spray from the front tire, so it is not a substitute for a full mudguard on wet roads. It also needs firm strap tension to stay put and won’t fit narrow-clearance road forks or fat bikes. I’d skip it if broad splash protection is the goal.
Pros:- Helps deflect dirt and spray away from the face and headset bearings
- Fits cross and gravel forks with 32–55 mm tires
- Weighs only 21 g
- Adjustable anti-slip straps allow positioning on the fork
Cons:- Does not stop general spray from the front tire
- Straps need firm tightening to keep the guard in place
- Does not fit narrow-clearance road forks or fat bikes
Best for: Gravel and cross riders with compatible forks who want a lightweight shield for their face and headset bearings on dirty trails.
Not ideal for: Riders seeking full front-wheel spray coverage, or those with narrow-clearance road forks or fat bikes.
- Brand:Ass Savers
- Model:MFM-1-BLK
- Material:Polypropylene
- Weight:21 g (0.05 lb)
- Compatible tire width:32–55 mm
- Compatibility:Cross and gravel forks
- Installation:Strap-on
- Item thickness:0.8 mm
Our verdict“Choose the Mudder Mini for light, targeted protection on compatible gravel forks, not as a replacement for a full front fender.”
BriskMore Handlebar Bike Mirrors with Convex Glass Lenses, 2-Pack
For gravel riders who share roads with traffic, I’d prioritize the BriskMore two-mirror set when a broad rear view matters more than keeping the cockpit minimal. Its 76 mm convex glass lenses provide a wide view, while the 360-degree rotation and 180-degree adjustment give riders room to set their viewing angle. Unlike the WOTOW Water-Resistant Reflective Bike Frame Bag, which organizes small items, these mirrors support a different need: checking behind without turning as far from the road ahead.
The main fit constraint is specific: handlebars need open-ended grips with a 14–24 mm inner diameter, or grips that can be modified. At 190 g for the pair, they also add more cockpit weight and bulk than a single compact accessory. I’d pass if your grips are closed-ended and you don’t want to alter them.
Pros:- Convex glass lenses offer a wide rear view
- 360-degree rotation and 180-degree adjustment support flexible positioning
- Includes two mirrors and a 4 mm hex key
- Can be installed on the left or right side
Cons:- Requires open-ended grips or grips modified with a hole
- Handlebar inner diameter must be 14–24 mm
- The pair weighs 190 g and adds cockpit bulk
Best for: Gravel commuters and mixed-surface riders who regularly ride near traffic and have compatible open-ended grips.
Not ideal for: Riders with closed-end grips they do not want to modify, or those prioritizing the lightest, least cluttered cockpit.
- Lens diameter:76 mm
- Handlebar compatibility:Open-ended grips with 14–24 mm inner diameter
- Lens and body materials:Glass lenses; nylon with 30% glass fiber
- Screw material:304 stainless steel
- Adjustability:360° rotation and 180° adjustment
- Weight:190 g
- Included components:2 mirrors, cleaning cloth, and 4 mm hex key
- Warranty:2 years
Our verdict“Pick these mirrors for a wide, adjustable rear view if your grips meet the bar-end fit requirements.”
ROCKBROS Waterproof Bicycle Frame Phone Bag
The ROCKBROS frame phone bag suits gravel riders who want navigation visible while keeping snacks and repair essentials close at hand. Its 1.6-liter compartment offers more than a phone sleeve, and the touch-sensitive window lets riders view and operate a compatible phone without removing it. Compared with the WOTOW Water-Resistant Reflective Bike Frame Bag, this ROCKBROS option is the clearer pick when screen access is a priority; the WOTOW instead emphasizes organized storage with interior pockets and a key hook.
That convenience comes with fit limits. The window supports phones up to 7 inches with slim cases, but thick cases can crowd the screen area, and Touch ID does not work through the cover. It is water-resistant rather than a guarantee against heavy rain, and the listing excludes large e-bikes and oversized top tubes. I’d skip it if your phone setup is bulky or your frame shape is outside those limits.
Pros:- 1.6-liter capacity combines phone access with space for ride essentials
- Touch-sensitive window supports screen use while riding
- Adjustable straps secure the bag to the frame
- Reflective details and water-resistant construction suit varied conditions
Cons:- Touch ID does not work through the screen cover
- Thick phone cases can crowd the phone window
- Not compatible with large e-bikes or oversized top tubes
Best for: Gravel riders who use phone navigation and want room for snacks or small repair gear in a frame-mounted bag.
Not ideal for: Riders with thick phone cases, large e-bikes, oversized top tubes, or a need for reliable Touch ID through the cover.
- Capacity:1.6 liters
- Dimensions:8.15 × 3.74 × 5 inches
- Weight:150 g
- Material:Polyester
- Mounting type:Bicycle frame
- Closure:Zipper
- Water resistance:Water resistant
- Phone compatibility:Up to 7 inches; slim cases only
Our verdict“Choose this bag if visible phone navigation and compact frame storage matter more than unrestricted phone access or heavy-rain protection.”
JXFUKAL 9.5L Waterproof Hard-Shell Bicycle Rack Bag
When a gravel ride calls for more cargo than a frame bag can sensibly hold, I’d look to the JXFUKAL 9.5L rack bag. Its hard-shell body, rain cover, and mix of inner mesh pockets, a top pocket, and an elastic cord make it better suited to organized gear or longer outings than the 1.6-liter ROCKBROS frame phone bag. The rack mount also shifts the load away from the top tube, leaving frame space available for bottles and other equipment.
This capacity depends on already having a compatible rack, and the bag weighs 0.89 kg before it is packed. The listing’s 9.5-liter specification is the dependable capacity figure, despite larger sizes appearing in the title. It includes a shoulder strap and handle for carrying off the bike, but no tail light. I’d skip it for rack-free bikes or riders who want a compact, lightweight setup.
Pros:- 9.5-liter capacity provides substantially more space than a small frame bag
- Hard-shell construction comes with a rain cover
- Main compartment, three inner mesh pockets, top pocket, and elastic cord aid organization
- Shoulder strap and handle make the bag easier to carry off the bike
Cons:- Requires a compatible bicycle or e-bike rack
- Weighs 0.89 kg before adding cargo
- Tail light is not included
Best for: Gravel riders with a compatible bicycle or e-bike rack who need organized cargo space for longer rides or commutes.
Not ideal for: Riders without a compatible rack, those keeping bike weight low, or anyone expecting a tail light to be included.
- Capacity:9.5 liters
- Dimensions:15.35 × 6.89 × 7.87 inches
- Weight:0.89 kg
- Material:PU-coated EVA
- Mounting:Rack mount with two buckle straps and one Velcro strap
- Compartments:1 main compartment, 3 inner mesh pockets, and 1 top pocket
- Water protection:Waterproof construction; rain cover included
- Compatibility:Bicycle and e-bike racks
Our verdict“Choose this rack bag for organized, higher-capacity carrying if your gravel bike already has a compatible rack.”
WOTOW Water-Resistant Reflective Bike Frame Bag, 2L
I’d pick the WOTOW frame bag for riders who want small essentials sorted rather than a clear phone window. Its 600D Oxford fabric, PU coating, and seam-sealed zipper help protect contents from rain and scratches, while the interior pockets and key hook make it easier to separate tools and personal items. Compared with the ROCKBROS Waterproof Bicycle Frame Phone Bag, it gives organization the lead; the ROCKBROS is the more direct choice for using a phone through a top-mounted window.
There is a specification mismatch worth factoring into the choice: the description says 2 liters, while product information lists 1 liter. I would not plan a tight packing fit around the larger figure. Its water resistance also does not promise dry contents in heavy rain, and the straps need a suitable frame placement. I’d skip it if you need verified capacity or waterproof protection for valuable electronics.
Pros:- Reflective panels on both sides improve visibility in low light
- Interior pockets and a key hook help organize small essentials
- Adjustable hook-and-loop straps allow flexible placement
- Double zipper and a large opening support convenient access
Cons:- Capacity is inconsistent: 2 liters in the description and 1 liter in product information
- Water-resistant construction may not keep contents dry in heavy rain
- No phone window for viewing or operating a device while riding
Best for: Gravel riders who want reflective, strap-on storage for tools, keys, and other small items, with internal organization.
Not ideal for: Riders who need a confirmed 2-liter capacity, protection in heavy rain, or a phone-viewing window.
- Capacity:2 L in description; 1 liter in product information
- Dimensions:8.6 × 6.1 × 2.17 inches
- Material:600D Oxford fabric with PU coating
- Mounting:Adjustable hook-and-loop straps
- Closure:Double-zipper main compartment
- Water resistance:Water resistant; seam-sealed zipper
- Compatibility:Most mountain, road, and commuter bicycles
- Organization:Main compartment with 2 interior pockets and a key hook
Our verdict“Choose the WOTOW for organized small-item storage and reflective details, but not when exact capacity or heavy-rain protection is a requirement.”
ROCKBROS Waterproof Bike Saddle Bag, 1.5 L
For gravel riders who want repair basics tucked out of the way, this 1.5-liter saddle bag offers a tidier alternative to larger storage such as the Rhinowalk Bicycle Handlebar Bag. Its 3D shell cushions the contents, while the strap-and-buckle mount keeps installation simple and avoids needing a separate rack. A reflective strip adds a useful visibility detail for rides that run into low light. The waterproof fabric and taped zipper can help shield essentials from splashes, but the seams are not waterproof, so I would not treat it as dependable protection in prolonged rain. Its compact capacity also limits what fits: it suits a tube and small tools better than bulkier layers or extensive touring gear. A taillight is not included, despite the reflective detail.
Pros:- Compact 1.5-liter capacity keeps basic repair gear under the saddle.
- 3D shell cushions stored items.
- Reflective strip adds visibility in low light.
- Strap-and-rubber-buckle mounting makes installation straightforward.
Cons:- Unsealed seams limit protection during prolonged water exposure.
- Taillight is not included.
- Small capacity is restrictive for extra layers or larger gear.
Best for: Gravel riders who want to carry a spare tube and a few small repair essentials beneath the saddle without adding a handlebar bag.
Not ideal for: Riders who need room for clothing or extensive tools, or who regularly ride for long stretches in heavy rain and need fully sealed storage.
- Capacity:1.5 liters
- Dimensions:9 × 3.22 × 3.93 inches
- Weight:135 g
- Material:Polyester
- Mounting:Seat mount with straps and rubber buckle
- Water resistance:Waterproof fabric and taped zipper; seams are not waterproof
- Closure:Zipper
- Warranty:1 year
Our verdict“Choose this compact saddle bag for a tube and small tools, but pick a larger storage option if your gravel rides call for more cargo or dependable heavy-rain protection.”
Lamicall Waterproof Bike Frame Bag with Phone Holder
When route directions and quick phone access matter more than maximizing cargo space, the Lamicall combines a touch-sensitive phone cover with a 1.3-liter frame bag. It fits phones from 4.7 to 7 inches, including models in thick cases, and its quick-release mount makes it easier to remove the bag when leaving the bike. Compared with the Rhinowalk Bicycle Frame Bag, this is the more phone-focused choice; the Rhinowalk is the more straightforward pick for carrying gear beneath the top tube. The Lamicall’s included rain cover adds another layer of weather protection, though its single compartment gives riders little room to separate items. I would also check the bike tube diameter before buying, since the mount’s stated fit range may rule out some frames.
Pros:- Touch-sensitive cover allows phone interaction while mounted.
- Fits phones measuring 4.7–7 inches, including thick-cased phones.
- Quick-release mount simplifies removal.
- Includes a rain cover and supports top-tube, frame, or stem mounting.
Cons:- Single compartment offers limited separation for phone and other items.
- Tube diameter must be checked for mounting compatibility.
- At 11.3 ounces, it is heavier than a minimal phone mount.
Best for: Gravel riders who follow phone-based navigation and want their phone visible and reachable while carrying a few small ride essentials.
Not ideal for: Riders who prefer a dedicated, organized cargo bag, use a frame outside the stated tube-diameter range, or do not want a phone mounted on the bike.
- Capacity:1.3 liters
- Dimensions:8.2 × 4.3 × 4.7 inches
- Weight:11.3 ounces
- Phone compatibility:4.7–7 inches, including phones with thick cases
- Mounting:Bicycle frame, top tube, or stem
- Compatible tube diameter:0.55–1.77 inches (12–45 mm)
- Water resistance:Waterproof design; includes rain cover
- Compartments:1
Our verdict“Pick the Lamicall if on-bike phone navigation is your priority; choose a conventional frame bag if you want simpler cargo storage and better organization.”
Rhinowalk Bicycle Frame Bag, 2.1/2.7 L
For riders who want more usable cargo space inside the bike’s frame, this triangular Rhinowalk bag offers 2.1 or 2.7 liters, more capacity than the phone-focused Lamicall. That extra room can suit tools, snacks, and other ride essentials without adding a handlebar bag. Its shape is aimed at road and gravel bikes, but fit depends on frame measurements: the top tube must be at least 16.5 inches long. The bag may also crowd bottle access or mounting space, so the product recommends bottles of 620 ml or less. Compared with the ROCKBROS saddle bag, this provides more frame-based storage but asks for closer attention to bike fit and bottle placement. The product details do not specify weight, materials, or weather protection, so I would not assume those advantages.
Pros:- Offers a choice of 2.1- or 2.7-liter capacity.
- Triangular under-top-tube placement uses frame space for storage.
- Designed for road and gravel bikes.
- Product guidance specifies bottle capacity to help riders plan fit.
Cons:- Requires a top tube at least 16.5 inches long.
- May affect bottle mounting position or access.
- Product details do not specify weight, material, or water resistance.
Best for: Gravel riders with a sufficiently long top tube who want more frame-mounted storage than a compact saddle bag provides.
Not ideal for: Riders with short top tubes, large bottle requirements, or limited frame space who cannot spare room around their bottle mounts.
- Capacity:2.1 or 2.7 liters
- Compatible bikes:Road and gravel bikes
- Mounting position:Beneath the top tube
- Minimum top tube length:16.5 inches
- Recommended bottle capacity:620 ml or less
- Shape:Triangular
Our verdict“Choose this frame bag if your bike meets the fit requirements and you want more cargo room than the ROCKBROS saddle bag, but check bottle clearance first.”
TXZSXS Adjustable Handlebar Bike Mirrors, Left and Right Set
Riders who want a mirror on each side get a matched pair here, with convex glass lenses intended to provide a wide rear view. The 360-degree rotation and 180-degree adjustment offer plenty of scope for setting the viewing angle, while included clamps, screws, and a hex key make installation more self-contained than a set that requires sourcing hardware. Compared with the BriskMore Handlebar Bike Mirrors, this listing specifies a left-and-right pair and its adjustment range, but its compatibility is framed around most flat handlebars; gravel bikes with drop bars may not be a fit. The ABS construction adds bulk, and the listed pair weighs 0.31 kg. Warranty details are also inconsistent: the description mentions lifetime coverage, while product specifications state one year.
Pros:- Pair includes one mirror for each side.
- Convex glass lenses provide a wide rear-view field.
- 360-degree rotation and 180-degree adjustment help position the view.
- Includes mounting hardware and a hex key.
Cons:- Fit is specified for most flat handlebars, so drop-bar compatibility is uncertain.
- Listed weight of 0.31 kg may be substantial for a pair of accessories.
- Warranty information conflicts between the description and product details.
Best for: Flat-bar gravel, hybrid, or e-bike riders who want rear visibility on both sides and adjustable mirror positioning.
Not ideal for: Drop-bar gravel riders or anyone who needs a clearly confirmed fit and consistent warranty terms before purchase.
- Quantity:2 mirrors (1 pair)
- Mounting type:Handlebar
- Fit:Most flat handlebars
- Lens:Convex glass with shatterproof film
- Adjustment:360° rotation; 180° adjustment
- Material:ABS
- Weight:0.31 kg
- Included components:Mirrors, stainless steel screws, adjustable clamps, and hex key
- Manufacturer warranty:1 year listed in product details
Our verdict“Choose this pair for adjustable rear visibility on flat bars, but confirm handlebar fit and warranty terms before ordering.”
Suruid Lightweight Bike Water Bottle Cages, 2 Pack, Black
For gravel riders building out basic hydration capacity, this two-cage set covers two mounting positions without requiring separate cage purchases. The wraparound arms are designed to hold bottles securely, and the included fittings make installation simpler. Polycarbonate construction keeps the cages light, while the stated fit includes many standard and oversized bottles. That makes this a more direct hydration solution than the Rhinowalk frame bag, which can affect bottle placement and recommends bottles of 620 ml or less. The main compatibility limit is on the bike, not the bottle: each mounting position needs threaded mounting holes. Some setups may also need washers for a tight fit, so I would check frame hardware rather than assume installation is identical on every bike.
Pros:- Two cages let riders outfit two mounting positions at once.
- Lightweight polycarbonate construction.
- Wraparound arms help retain bottles.
- Mounting fittings are included and fit covers many standard and oversized bottles.
Cons:- Requires threaded mounting holes on the bike.
- Washers may be needed to achieve a tight fit.
- Product details do not specify a bottle-size range or cage weight.
Best for: Gravel riders with two threaded cage mounts who want to add bottle capacity using a matched pair of lightweight cages.
Not ideal for: Riders whose frames lack threaded mounting holes, or those who need a guaranteed snug fit without checking hardware or adding washers.
- Quantity:2 cages
- Material:Polycarbonate
- Color:Black
- Dimensions:5.39 × 3.07 × 2.68 inches
- Fit:Most standard and oversized bike bottles
- Bike compatibility:Bikes with threaded mounting holes
- Included:Mounting fittings
Our verdict“Choose this set if your gravel bike has two threaded bottle mounts and you want straightforward hydration capacity; skip it if your frame lacks cage bosses.”
How We Picked
I compared these accessories by the job they do on gravel rides: carrying essentials, supporting repairs, protecting against spray, improving visibility, or providing hydration access. I weighed practical usability, stated capacity and protection, likely fit constraints, and how much each item could contribute to a ride without adding unnecessary bulk. A bag’s size or feature count alone did not make it a stronger pick; its usefulness depends on how well it matches a rider’s load and bike setup.
The ranking gives priority to broadly useful items and clear use cases. The Crankbrothers M 19 ranks first because a multi-tool can support a wide range of roadside adjustments, while the Topeak saddle bag and larger JXFUKAL rack bag represent distinct storage needs. Specialized accessories rank lower for general use but may be the better choice for riders with a specific concern, such as mud spray, phone access, or rear visibility. I also treated product labels as claims to check against real-world needs: buyers should confirm mounting compatibility and use extra protection for valuables when water exposure is a concern.
Factors to Consider When Choosing Best Gravel Bike Accessories
Before choosing from this roundup, I would start with the problem that most limits your rides, rather than buying accessories as a bundle. Gravel routes can combine rough surfaces, long gaps between services, changing weather, and limited mounting space. The right setup balances carrying capacity and preparedness against weight, fit, and access while riding.
Match Storage to What You Actually Carry
List the items you expect to bring on a typical ride before choosing a bag by its advertised capacity. A tube, levers, and a compact tool may fit a small saddle bag, while layers, food, and extra equipment call for more space or more than one bag. Oversizing can add bulk and make it harder to reach essentials, while undersizing may push items into jersey pockets or leave them at home. Also check how the bag attaches and whether its position could rub against your legs, tire, or frame. For longer trips, split gear by use so repair items remain easy to reach even when other luggage is full.
Check Frame and Mounting Compatibility First
Gravel bikes vary in frame shape, available bottle mounts, cable routing, and clearance around the seat and handlebar. A bag that looks compact in a listing can still interfere with knees, steering, or bottle access on a particular frame. Measure the space available and compare it with the bag’s dimensions before buying, especially for top-tube or phone-holder designs. Check mounting straps and attachment points for surfaces that could scuff paint on rough roads. If your bike has limited clearance or a small frame, a smaller bag or a different mounting location may be more useful than chasing extra capacity.
Treat Weather Protection as a Layered System
Water-resistant and waterproof labels do not remove the need to think about seams, closures, and how long gear may be exposed to rain or spray. A bag may handle splashes yet still let moisture in through a zipper during sustained wet weather. Keep phones, documents, and spare electronics in a sealed inner pouch if getting them wet would end a ride. Mudguards can reduce spray, but their coverage and fit differ from full fenders, so they may not keep a rider or luggage clean in every condition. Choose protection based on the weather you routinely ride in, not on the most optimistic label alone.
Prioritize Repair Gear Before Convenience Add-Ons
For remote routes, the ability to fix a common problem can matter more than carrying a phone in an easy-to-view position. A multi-tool is useful only if it includes the fittings your bike needs, so check your components and practice basic adjustments at home. A tool also cannot replace a spare tube or other repair supplies suited to your tires and setup. Once those basics are covered, storage upgrades, mirrors, or phone holders can improve comfort and access. Riders staying close to services may reasonably favor convenience, while those far from help should reserve space for repairs first.
Balance Visibility With Fit and Riding Position
Mirrors can help riders monitor traffic without turning their head as far, but their usefulness depends on placement, stability, and a clear view around the rider’s body. A mirror that works on one handlebar shape may not fit another, so check its mounting method and available space near controls. Phone-holder bags also need a viewing angle that remains readable without encouraging prolonged glances away from the road. Do not assume that a mirror or phone window replaces safe shoulder checks or route planning. If you use a handlebar bag and mirror together, confirm that neither blocks the other’s view or interferes with braking and shifting.
Pay for Capacity or Features You Will Use
Additional capacity, hard-shell construction, or a phone window can be helpful, but each may add bulk or create another fit constraint. A premium-feeling feature is worthwhile when it solves a repeated problem, such as carrying a larger load or accessing a phone for navigation. For occasional short rides, a simple bag and a dependable tool may cover more needs with less clutter. Compare the total setup rather than judging one accessory alone: a rack bag may require a rack, while a compact frame bag may compete with bottles. Choose the smallest combination that supports your usual rides, then add specialized accessories only when a clear need appears.
Frequently Asked Questions
Which accessory should I buy first for gravel riding?
I would start with a repair tool and a way to carry the essentials for a flat or minor adjustment, since being unable to address a basic problem can cut a ride short. The Crankbrothers M 19 is the broadest repair-focused option in this lineup, but check that its tool selection matches your bike. Pair it with a suitable spare tube or tubeless repair supplies, tire levers, and a pump or inflator; the tool alone is not a full repair kit. If you already carry those items, choose the accessory that addresses your most frequent frustration, such as storage, spray, or visibility.
Should I choose a saddle bag, frame bag, handlebar bag, or rack bag?
Choose based on the shape and weight of your load, the bike’s available space, and how often you need access while riding. Saddle bags suit compact repair items, while frame bags use central space and can carry gear that you want near the bike’s center. Handlebar bags can keep selected items accessible, though their position may affect cockpit space. A rack bag makes more sense when you need greater carrying capacity and your bike has a compatible rack. Before deciding, check clearances and whether the loaded bag will block bottles, controls, or your preferred riding position.
Can I rely on a waterproof-labeled bike bag to protect my phone?
I would not rely on a product label alone when a wet phone could create a serious problem. Water can enter through closures or seams, and prolonged rain or mud spray can be more demanding than a brief splash. The frame bags with phone holders in this roundup may add convenient access, but fit and screen usability also vary with frame size and riding position. Use a sealed inner pouch for valuable electronics if you expect sustained wet conditions. Check the closure design and care instructions before treating any bag as your only weather barrier.
Do gravel riders need both a mirror and a phone holder?
No; they address separate needs, and neither is essential for every rider. A mirror can make it easier to monitor traffic behind you, while a phone holder can support navigation, but both depend on a secure, useful position. On rough roads, check that the mounts stay clear of controls and that vibration does not make the view or screen difficult to use. A handlebar bag may compete for space with a mirror, so plan the cockpit layout before buying both. If you use a phone for directions, set the route before riding and keep attention on the road.
How much storage do I need for a day ride?
There is no single capacity that fits every day ride; the right amount depends on distance, weather, access to services, and what you carry for repairs. Start by laying out your usual essentials, including food, a layer, and the tire supplies your setup requires, then choose storage that fits them without forcing the bag full. A compact saddle bag can cover a minimal kit, while a larger frame or rack bag gives room for additional layers and supplies. Avoid filling unused space simply because it is available, since excess load can add clutter and make items harder to find. For remote routes, prioritize repair supplies and water access before optional gear.
Conclusion
For the broadest practical starting point, I recommend the Crankbrothers M 19 as best overall because a versatile tool supports roadside adjustments across many kinds of gravel rides. The Topeak Aero Wedge Pack is my best value-style choice for riders who want compact storage that can expand when needed, while the larger JXFUKAL rack bag is the premium-style pick for carrying more gear when a rack-compatible setup suits your bike. Beginners should start with a basic repair kit and a straightforward storage solution before adding phone holders or multiple visibility accessories. For specific needs, choose the Ass Savers Mudder Mini for added spray coverage, a frame bag with a phone holder for route access, or the mirror set that best fits your handlebars. Match the accessory to your bike and usual route, and prioritize fit and function over adding every option at once.
