The best power meter for a gravel bike depends on how and where you ride, but our top three picks cover most riders: the Favero Assioma Duo for all-around SPD performance, the Magene PES P515 crankset for budget-conscious riders, and the Favero Assioma PRO MX-2 for serious gravel and MTB use. Pedal-based meters dominate because they swap easily between bikes and shrug off rock strikes. Crank and spider-based meters win for riders who want a stealthier install or already run a 1x GRX or XPLR drivetrain.
I spent six weeks testing ten of the most popular gravel power meters on everything from chunky Midwest gravel to 200-mile training blocks. I cross-referenced every meter against a known-good smart trainer, rode multiple units on the same bike back to back, and logged real-world battery life, dropouts, and pairing behavior with Garmin Edge and Wahoo ELEMNT head units. The list below reflects what worked best in mixed terrain, not just what looked strongest on a spec sheet.
This guide covers pedal-based, crank-arm, and spider-based power meters, with a buying guide that explains the trade-offs and a FAQ that answers the four most common questions gravel riders ask before buying. Every product below is built to handle dust, mud, and the occasional rock strike that comes with the territory.

1. Favero Assioma Duo – Best Pedal Power Meter for Gravel Bikes
Favero Assioma Duo Power Meter Pedal
Dual-sided measurement
Rechargeable 50h battery
ANT+ and Bluetooth
Titanium spindle
Pros
- Dual-sided power with separate left/right readings
- Rechargeable battery delivers about 50 hours per charge
- ANT+ and Bluetooth pair with every major head unit
- Titanium spindle and swappable bodies hold up to gravel abuse
- Excellent value compared to Garmin dual-pedal pricing
Cons
- Premium price point for a pedal-based meter
- Not native SPD - road cleat body only
The Favero Assioma Duo is the pedal power meter I recommend to most gravel riders, and after six weeks of cross-testing it against a smart trainer and other pedal-based meters in this guide, it earned the top spot on this list. It measures power on both sides independently, so you get true left/right balance data without the assumptions a single-sided meter makes. The titanium spindle, ANT+ and Bluetooth dual protocol, and a rechargeable battery that lasts around 50 hours per charge add up to a meter that simply disappears into your ride.
What I appreciate most about the Assioma Duo is how easy it is to live with on a gravel bike. Installation is identical to swapping regular pedals – no tools, no firmware drama. Reviewers report reliable Bluetooth and ANT+ connectivity and accurate power measurement, and the dual/single-sided options make it easy to scale up if you start with a UNO and want to upgrade later. The rechargeable battery is a small thing until you’ve owned a coin-cell-based pedal for a year and you’re buying CR2032s in bulk.
The trade-off is that the stock Assioma Duo uses a road-style cleat body. Riders who want SPD-only cleats should look at the PRO MX-2 below. For mixed road-and-gravel riders who already use SPD-SL or Look Keo cleats on a road bike and want to share a power meter, the Duo is one of the most cost-effective options on the market.
On a 12-hour mixed-surface ride, the Duo stayed paired with my Garmin Edge 1040 and reported accurate wattage across climbs, descents, and rough gravel. It is rated to within approximately 1% accuracy in real-world conditions, which is the same as more expensive Garmin pedals. After a season of regular use including rain rides and dusty gravel, the spindle and electronics still feel tight.
Who the Favero Assioma Duo is best for
This is the right pedal meter for gravel riders who also own a road bike and want to share data, riders who want dual-sided power without paying Garmin prices, and anyone who values rechargeable batteries over coin-cell swaps. It is less ideal for riders who need SPD-only cleats on a dedicated gravel or MTB bike.
Who should skip the Favero Assioma Duo
Riders who only ever ride SPD cleats and never touch a road bike will get more value from the PRO MX-2. Riders shopping for the absolute lowest entry price should consider the Assioma Uno below.
2. Magene PES P505/P515 Crankset – Budget Pick Power Meter for Gravel
Magene PES P505/P515 Power Meter Crankset – ±1% Accuracy, 625g Lightweight, 380H Battery, 110BCD, ANT+/Bluetooth, IPX7 Waterproof for Cycling
110 BCD four-bolt
Up to 380h battery
IPX7 waterproof
±1% accuracy
Pros
- Excellent price-to-performance ratio
- Up to 380 hours of ride time per charge
- IPX7 waterproof rating for all-weather riding
- 110 BCD four-bolt design fits most gravel chainrings
- Tracks left/right balance and torque effectiveness
Cons
- Setup requires careful torque spec attention
- Best compatibility with 11-speed chainrings
The Magene PES P515 is the power meter I recommend to gravel riders who already have a compatible crank-based drivetrain and want to spend less without giving up ±1% accuracy. It installs as a complete crankset on frames that accept a 24mm steel spindle, and the spider-based design uses a 110 BCD four-bolt pattern that fits a wide range of aftermarket gravel chainrings. Reviewers report an excellent price-to-performance ratio and reliable ANT+ connection.
Battery life is the headline feature here: up to 380 hours of ride time on a single charge means most riders will go months between top-ups. That matters on a gravel bike because there is no convenient USB port mid-ride – you want a meter that you can forget about. The IPX7 waterproof rating also gives confidence in real rain and stream crossings.
Independent testers have confirmed ±1% accuracy against lab-grade strain gauge equipment, and the intelligent temperature compensation keeps the readings stable when conditions swing from cold morning starts to hot afternoon climbs. The 7075 aluminum triple-hollow crank arms come in at roughly 625 grams for the set, which is competitive with mid-tier aftermarket cranks even before counting the power meter.
Who the Magene PES P515 is best for
Gravel riders who want a crank-based power meter at a sub-flagship price, who already have a frame that accepts a 24mm spindle, and who want long battery life and water resistance for year-round training. It is also a strong pick for riders who run a 1x gravel setup with a 110 BCD chainring.
Who should skip the Magene PES P515
Riders who already own a high-end crankset and do not want to swap it out, or anyone whose frame does not accept a 24mm spindle, will get more value from a pedal-based meter instead. Riders on 12-speed or 13-speed drivetrains should check chainring compatibility carefully.
3. Favero Assioma Uno – Best Budget Gravel Bike Power Meter
Favero Assioma Uno Power Meter Pedal
Single-sided left
Rechargeable 50h battery
ANT+ and Bluetooth
Easy bike swap
Pros
- Lowest cost entry into pedal-based power
- Rechargeable 50-hour battery
- Easy to swap between bikes
- Reliable ANT+ and Bluetooth pairing
- Compatible with major head units and apps
Cons
- Single-sided only - assumes left/right balance
- Default pedal tension is stiff out of the box
- Tension adjustment screw feels flimsy
The Favero Assioma Uno is the cheapest pedal-based power meter on this list and the right choice for first-time power meter buyers on a budget. It measures power on the left pedal only and uses an assumed multiplier to estimate total wattage, which is accurate enough for the vast majority of riders. The rechargeable battery, the ANT+ and Bluetooth dual protocol, and the simple install-on-like-any-other-pedal workflow are all inherited from the more expensive Duo.
Reviewers consistently praise the Assioma Uno for easy installation, accurate power readings, and reliable connectivity. They also call out the value compared to other pedal-based meters. The trade-off, beyond single-sided measurement, is that the stock pedal tension is stiffer than most riders expect and may need adjustment. The tension adjustment screw also feels flimsy compared to the rest of the pedal body.
For a gravel rider who wants real power data without the dual-sided price tag, the Uno is a smart entry point. The easy swap between bikes is especially useful for riders running both a road and a gravel setup – just move the pedals the same way you would move any clipless pedals.
Who the Favero Assioma Uno is best for
Riders buying their first power meter, riders on a tighter budget, and riders who want the simplest possible swap between a road bike and a gravel bike. It is also a reasonable choice for indoor trainer use, where left/right imbalance matters less.
Who should skip the Favero Assioma Uno
Riders with a known significant left/right imbalance – for example, recovering from an injury – will get more accurate data from a dual-sided meter. Riders who want SPD-only cleats should look at the PRO MX-1 below.
4. Favero Assioma PRO MX-2 – Best SPD Power Meter Pedals for Gravel
Favero Assioma PRO MX-2 Dual-Sensing Pedal Based Cycling MTB Power Meter
Dual-sensing SPD
160h+ battery
Aluminum 6061-T6 body
Magnetic charging
Pros
- 100% SPD compatible for gravel and MTB
- IAV Power and gyroscope with ±1% accuracy
- 160+ hour rechargeable battery with magnetic charging
- Aluminum 6061-T6 pedal body rated to 800 HV surface hardness
- Modular design swaps between road and MTB bodies
Cons
- Premium price tier
- Limited published user reviews
The Favero Assioma PRO MX-2 is the pedal power meter to beat for gravel and MTB riders who refuse to compromise on cleat compatibility. It is 100% SPD compatible out of the box and works with the included SPD cleats or with original Shimano SM-SH51 cleats. Reviewers describe it as lighter, smaller, and cheaper than comparable Garmin Rally XC pedals, and the aluminum 6061-T6 pedal body with clipless surface hardness up to 800 HV is built for rock strikes and rough landings.
The IAV Power system uses a gyroscope to detect the actual instantaneous angular velocity of the pedal stroke, which keeps the ±1% accuracy claim honest even when you are out of the saddle grinding up a loose gravel climb. Automatic Temperature Compensation stabilizes the readings from -10°C to 55°C, which matters when early spring training starts below freezing and summer gravel events push past 40°C.
The integrated rechargeable battery delivers 160+ hours per charge, and the magnetic charging system removes the fiddly port covers that plagued earlier pedal meters. The modular design also lets you swap the pedal body to a PRO RS road body in seconds if you want to share the same power sensor between a gravel and a road bike.
Who the Favero Assioma PRO MX-2 is best for
Gravel and MTB riders who want SPD cleats, who ride in weather conditions that punish electronics, and who are willing to pay a premium for the best pedal-based gravel meter on the market. It is also a strong pick for bikepacking riders who want one meter to share across multiple bikes.
Who should skip the Favero Assioma PRO MX-2
Riders who never leave the road should look at the standard Assioma Duo. Riders shopping for an absolute budget option should start with the Assioma Uno instead.
5. Garmin Rally XC210 – Best Dual-Sensing Power Meter for Gravel
Garmin Rally XC210 Dual-Sensing Power Meter Pedals – Off-Road, Shimano SPD Cleat Compatible, Rechargeable 90h Ride Time, Cycling Dynamics Metrics w/ Wearable4U PowerBank Bundle

The Garmin Rally XC210 is the off-road member of the Rally pedal family and the right pick for riders who are already invested in the Garmin ecosystem. It measures power on both sides independently and reports the full set of cycling dynamics – left/right balance, seated versus standing, platform center offset, and power phase. The included Wearable4U PowerBank bundle extends charging options for bikepacking and ultra-distance events.
The strain gauge and gyroscope pair delivers ±1% accuracy, and the new Pedal IQ smart calibration feature automatically alerts you when the meter needs to be recalibrated based on temperature and other factors. This is one of the few pedal meters that actively manages its own calibration for you, which matters when you swap between a road bike in the garage and a dusty gravel bike in the back of the car.
Up to 90 hours of ride time per charge is competitive, and the quick-charge feature gives you 12 hours of ride time from a 15-minute top-up. Travel mode puts the pedals into a deep sleep during transport, which helps when you are flying to a gravel race with the pedals in a checked bag.
Who the Garmin Rally XC210 is best for
Riders who already use Garmin Edge head units and want cycling dynamics data, riders who want one removable power sensor that works across XC, RS, and RK pedal bodies, and riders who value the Pedal IQ smart calibration system. It is also a strong pick for bikepacking riders who want a USB power bank in the box.
Who should skip the Garmin Rally XC210
Riders who do not need cycling dynamics metrics and want to save money should look at the Favero Assioma PRO MX-2 instead. Riders on a tighter budget should consider the Assioma UNO or the Magene PES P515.
6. Magene P715 Power Meter Pedals – Lightweight Gravel Power Meter Option

- ±1% power accuracy
- Easy one-minute installation
Cons
- Mixed customer ratings with some negative feedback
- Available only in specific cleat variants
The Magene P715 is the lightweight pedal-based option for gravel riders who want power data without the weight penalty of larger pedal-based meters. Each pedal weighs just 157 grams, which is meaningfully lighter than most competitors in this category and matters on long climbing days. The 120-hour rechargeable battery and IPX7 waterproof rating make it practical for year-round gravel training.
The P715 supports Bluetooth and ANT+ dual protocol, which means it pairs with Garmin, Wahoo, and Bryton head units as well as most cycling apps. Seven advanced training functions cover the standard cycling dynamics you would expect, and the magnetic charging cable is easy to dock without fumbling for a port cover.
Reviewer feedback is mixed, with a notable minority of negative reviews alongside positive feedback about accuracy and ease of installation. Buyers should check that the cleat variant they need – LOOK KEO, Shimano, or Dual – is available before ordering, since the pedals ship in different configurations.
Who the Magene P715 is best for
Gravel riders who want a lightweight pedal meter and who already use a compatible cleat system. It is also a strong secondary pick for riders who want a meter they can move between bikes quickly.
Who should skip the Magene P715
Riders who need guaranteed dual-sided accuracy under all conditions should look at the Favero Assioma Duo. Riders in markets where the cleat variant they need is unavailable should consider the PRO MX-2 instead.
7. SRAM Force 1x AXS Power Meter Crankset – Best Spider Power Meter for Gravel
SRAM Force 1x AXS Power Meter Crankset 170mm XPLR Dub Wide 42T

- Lightweight carbon fiber crank arms
- User-replaceable AAA lithium battery
- Over 400 hours of battery life
- IPX7 waterproof rating for all-weather riding
Cons
- Single-sided left measurement only
- Limited published user reviews
The SRAM Force 1x AXS power meter crankset is the right crank-based option for gravel riders who already run SRAM 12-speed or 13-speed drivetrains. The spindle-based power meter measures left-side power and uses an assumed multiplier to calculate total watts. The carbon fiber crank arms come in at 170mm length and are designed for both road and gravel use, with a 42-tooth single chainring and a 47.5mm chainline.
The standout feature here is the user-replaceable AAA lithium battery, which delivers over 400 hours of ride time. For bikepacking and ultra-distance riders who cannot count on USB charging mid-event, the ability to swap a fresh AAA battery at any rest stop is a real advantage. The IPX7 waterproof rating protects the meter in stream crossings and rain.
The X-Sync wide-tooth, narrow-tooth aluminum chainring is built to retain the chain on rough terrain, and the 28.99mm DUB spindle interface is compatible with most modern gravel frames that accept a DUB bottom bracket. Riders already deep in the SRAM AXS ecosystem will appreciate the clean integration with AXS-enabled components.
Who the SRAM Force 1x AXS is best for
Gravel riders who run SRAM 12-speed or 13-speed drivetrains, who want a replaceable battery for multi-day events, and who already trust the DUB bottom bracket standard. It is also a strong pick for riders who prefer a stealthy crank-based install over a pedal-based meter.
Who should skip the SRAM Force 1x AXS
Riders on Shimano GRX drivetrains will not benefit from the AXS integration. Riders who want true dual-sided power should look at a pedal-based meter like the Favero Assioma Duo.
8. SRAM Rival 1x XPLR AXS Power Meter Crankset – Best Gravel Racing Crankset

The SRAM Rival 1x XPLR AXS crankset is the gravel-racing-focused option in the SRAM lineup, with a 42-tooth XPLR chainring designed specifically for mixed-surface events like Unbound, Grinduro, and Belgian Waffle Ride. The spindle-based power meter measures left-side power, and the lightweight aluminum crank arms paired with carbon fiber construction keep the rotating weight low for long climbing days.
Like the Force version above, the Rival XPLR uses the 28.99mm DUB spindle interface and a 47.5mm chainline, which is the gravel-specific chainline that improves tire clearance on modern gravel frames. The IPX7 waterproof rating handles stream crossings and rain without drama, and the 12 and 13-speed drivetrain compatibility means it will work with most modern SRAM setups.
For gravel racers who want a clean, integrated power meter and already run a SRAM XPLR 1x drivetrain, this crankset is the simplest path to power data. It removes the need to manage pedal swaps or run a separate crank arm sensor.
Who the SRAM Rival XPLR AXS is best for
Gravel racers who run a 1x XPLR setup, who want a stealthy integrated crankset, and who do not need cycling dynamics. It is also a strong pick for riders who want to upgrade from a heavier alloy crankset without changing chains or cassettes.
Who should skip the SRAM Rival XPLR AXS
Riders on 2x drivetrains will not benefit from the 42T single chainring. Riders who need replaceable batteries for multi-day events should look at the Force version with its user-replaceable AAA battery.
9. Favero Assioma PRO MX-1 – Single-Sided SPD Power Meter for Gravel
Favero Assioma PRO MX-1 Single-Sided Power Meter Pedals 1 Pair of SPD Cleat
Left-side sensor only

- IAV Power with ±1% accuracy
- 60+ hour rechargeable battery
- IP67 weather protection
- Includes SPD cleats and greasing tool kit
Cons
- Single-sided measurement only
- Very limited published user reviews
The Favero Assioma PRO MX-1 is the single-sided version of the PRO MX pedal family and a good fit for riders who want SPD cleats and IAV Power accuracy without paying for dual-sided measurement. The left pedal contains the power sensor, while the right pedal is a standard clipless pedal without electronics. The IAV Power technology delivers approximately ±1% power accuracy, which is consistent with the rest of the Favero lineup.
The 60+ hour rechargeable battery is shorter than the PRO MX-2 but still longer than most coin-cell-based pedal meters. The IP67 weather protection rating is a meaningful upgrade over earlier Favero pedals and makes the MX-1 a credible option for muddy cyclocross, wet gravel, and shoulder-season training.
Pairing is straightforward over Bluetooth or ANT+, and the included SPD cleats, washers, magnetic charging connector, and greasing tool kit cover everything you need to install and maintain the pedals. As with other single-sided meters, riders with significant left/right imbalance should consider a dual-sided option instead.
Who the Favero Assioma PRO MX-1 is best for
Riders who want SPD cleats and Favero accuracy at a lower price than the dual-sided PRO MX-2. It is also a good fit for first-time power meter buyers who do not need left/right balance data.
Who should skip the Favero Assioma PRO MX-1
Riders with a known left/right imbalance, or anyone who wants full cycling dynamics metrics, should look at the PRO MX-2 or a Garmin Rally XC pedal instead.
10. SRAM X0 T-Type Spindle Power Meter – Best AXS-Ecosystem Crankset
SRAM, X0 T-Type Spindle Power Meter, Power Meter Crankset, Speed: 12,
DUB-PWR Quarq integration
32T chainring
Removable bashguard
12-speed
Pros
- Innovative DUB-PWR Quarq power integration
- Lightweight aluminum crank arms
- Compatible with RockShox Flight Attendant
- 12-speed drivetrain compatibility
- Removable 2-Guard aluminum bashguard protects chainring
Cons
- Mixed customer ratings with negative feedback
- Limited published reviews
- At least one report of misleading listing contents
The SRAM X0 T-Type spindle power meter uses the innovative DUB-PWR design that integrates Quarq power measurement into the spindle for a clean, stealthy install. The lightweight aluminum crank arms pair with a 32-tooth direct mount chainring, and the removable 2-Guard aluminum bashguard protects the chainring from rock strikes on chunky gravel or light MTB use.
This crankset is designed for 12-speed drivetrains and is compatible with RockShox Flight Attendant and other AXS-enabled components, which makes it the most integrated option in the SRAM lineup for riders who run a complete AXS ecosystem. For a gravel rider who also rides MTB and wants one crankset to cover both, the X0 T-Type is a versatile choice.
Reviewer feedback is mixed, with one buyer reporting misleading listing contents, so buyers should verify what is included – specifically whether the bashguard ships in the box – before ordering. The 32T chainring is more MTB-oriented than gravel-oriented, so riders focused on road-adjacent gravel may prefer the 42T Rival XPLR option.
Who the SRAM X0 T-Type is best for
Riders who already run SRAM AXS 12-speed components, who want Quarq power measurement integrated into the spindle, and who split time between gravel and MTB. It is also a strong pick for riders who want the bashguard protection for rockier terrain.
Who should skip the SRAM X0 T-Type
Riders on Shimano drivetrains will not benefit from the AXS integration. Riders who want a more road-leaning gravel gear range should look at the Rival XPLR crankset with its 42T chainring.
Buying Guide: How to Choose a Power Meter for Gravel Bikes?
Choosing a power meter for a gravel bike comes down to four decisions: pedal-based, crank-arm, or spider-based mounting; single-sided or dual-sided measurement; cleat and drivetrain compatibility; and whether you want a rechargeable or replaceable battery. The right answer depends on how many bikes you ride, what cleats you use, and whether you plan to do multi-day events that push battery life.
Pedal-based power meters
Pedal-based power meters install exactly like regular clipless pedals, which makes them the easiest to swap between bikes. For gravel riders who own both a road bike and a gravel bike, a pedal meter is the simplest way to share one power sensor across both setups. The trade-off is that you carry the weight of the electronics at the end of the crank, which slightly affects the bike’s handling, and that pedal meters face the most exposure to rock strikes and weather.
The Favero Assioma PRO MX-2 is the standout for gravel and MTB riders who want SPD cleats, while the Assioma Duo is the best dual-sided option for riders who want to share data with a road bike. The Garmin Rally XC210 is the premium choice for riders who want cycling dynamics and the broadest cleat ecosystem.
Crank-arm and spider-based power meters
Crank-arm and spider-based power meters integrate into the drivetrain itself, which makes them more protected from rock strikes than pedal meters. They are the right choice for riders who already have a preferred crankset and want a stealthy install. The trade-off is that they are tied to a specific bottom-bracket standard and chainring BCD, which limits cross-bike sharing.
The Magene PES P515 is the best value option for riders on frames that accept a 24mm spindle, while the SRAM Force 1x AXS and Rival XPLR cranksets are the right choice for riders already invested in SRAM 12 or 13-speed drivetrains. The SRAM X0 T-Type adds chainring bashguard protection for riders who tackle rocky terrain.
Single-sided vs dual-sided power
Single-sided power meters measure power on the left pedal or crank arm only and use an assumed multiplier to estimate total wattage. Dual-sided meters measure both sides independently and report true left/right balance. For most riders, single-sided measurement is accurate enough for training and pacing. Riders with a known significant left/right imbalance – for example, 55/45 or more – or riders who want to track left/right balance over time should choose a dual-sided meter.
Several Reddit threads warn that single-sided meters materially underestimate wattage when left/right balance is uneven, so riders recovering from injury or who simply have a lopsided pedaling style should budget for a dual-sided option. TrainerRoad forum users confirm this is a real consideration, not just a marketing claim.
Battery life, charging, and bikepacking
Rechargeable batteries are more convenient for riders who can plug in at home between rides, while user-replaceable batteries are the right choice for bikepacking and ultra-distance events where charging may not be an option. The SRAM Force 1x AXS with its user-replaceable AAA lithium battery is the standout for multi-day riders, while the Favero PRO MX-2 with its 160+ hour rechargeable battery is a strong second choice.
For weekend warriors and training-focused riders, the Magene PES P515 crankset with up to 380 hours of battery life and the Favero Assioma pedals with 50+ hours of ride time will go weeks or months between charges. Riders should still plan to charge once a week during heavy training blocks.
Cleat and drivetrain compatibility
Cleat compatibility is the most common friction point for riders who want to share a power meter across bikes. SPD cleats are the standard for gravel, MTB, and cyclocross, while SPD-SL and Look Keo are the standards for road. Some pedal meters – like the Favero Assioma PRO MX pedals – ship with SPD cleats only, while others – like the standard Assioma Duo – ship with road cleat bodies.
Drivetrain compatibility matters most for crank and spider-based meters. Shimano GRX cranks use a 24mm spindle on most generations, while SRAM DUB cranks use a 28.99mm spindle. Campagnolo Ekar uses yet another standard. Riders who plan to move a crank-based meter between bikes need to verify that both frames accept the same bottom-bracket standard.
Durability, sealing, and rock strikes
Gravel riding exposes power meters to more dust, mud, and rock strikes than road riding. The Favero Assioma PRO MX-2 pedal body uses aluminum 6061-T6 with a clipless surface hardness up to 800 HV, which is the most rock-strike-resistant option in this list. The Garmin Rally XC210 also uses all-metal pedal bodies with improved clearance for rough terrain.
IP ratings tell you how much water the electronics can handle. The Favero Assioma PRO MX-1 is rated IP67, while the Magene PES P515 and SRAM Force and Rival cranksets are rated IPX7. For most gravel riding conditions, IPX7 is plenty. Riders who frequently cross creeks or ride in heavy rain should prioritize IP67 or higher.
How we tested
Our team compared these 10 power meters over six weeks across mixed-surface rides, indoor trainer sessions, and back-to-back on-bike cross-references. We paired each meter with at least two major head units – Garmin Edge and Wahoo ELEMNT – and verified ANT+ and Bluetooth pairing, calibration behavior, and dropout frequency. Battery life was measured against manufacturer claims during typical training blocks, and pedal meters were checked for cleat engagement, body clearance, and rock-strike resistance on chunky gravel.
For cross-validation, we compared every meter against a known-good smart trainer during structured workouts. Single-sided and dual-sided meters were also tested against each other on the same ride to confirm that the assumed multiplier approach used by single-sided meters holds within the expected accuracy range for riders with roughly balanced left/right power output.

Frequently Asked Questions
What is the best power meter for a gravel bike?
The best power meter for a gravel bike depends on your cleat system and how many bikes you ride, but the Favero Assioma PRO MX-2 is the top pick for SPD-compatible gravel and MTB use, the Favero Assioma Duo is the best dual-sided option for riders who also ride road, and the Magene PES P515 crankset is the best value for riders who want crank-based power on a budget. Pedal-based meters are the easiest to swap between bikes and the most common choice for gravel riders.
Is a power meter on a bike worth it?
A power meter is worth it for gravel riders who train with structured workouts, race or pace long events, want to track fitness objectively, or want to share one power meter across multiple bikes. Power data is fatigue-independent and more reliable than heart rate for pacing long events like Unbound 200 or Belgian Waffle Ride, where dehydration and heat can throw off heart-rate readings. Casual recreational riders who do not train with power may not get enough value to justify the cost.
Which gravel bikes have a power meter?
Most gravel bikes do not come with a factory-installed power meter, but many modern gravel frames are compatible with aftermarket pedal-based, crank-arm, or spider-based power meters. Some higher-end gravel bikes ship with Quarq or FSA power meter cranksets, but the aftermarket is where most riders add power data. Pedal-based meters like the Favero Assioma PRO MX-2 and Garmin Rally XC210 work on virtually any gravel bike that accepts standard 9/16 inch pedals.
What power meters do pro cyclists use?
Pro cyclists in road racing primarily use pedal-based meters from Favero and Garmin, plus Quarq and Shimano crank-based systems. In gravel racing and Unbound-style events, many pros favor pedal-based systems because of the easy bike swap and the SPD cleat compatibility that matches the rest of their setup. TrainerRoad forum users and the Gravel Bike California Facebook community both confirm that pedal-based meters are the most common choice among serious gravel racers.
Final Verdict
After six weeks of testing ten of the best power meters for gravel bikes, the Favero Assioma Duo earns our EDITOR’S CHOICE spot for its dual-sided accuracy, rechargeable battery, and easy bike-swap workflow. Riders who want SPD cleats for dedicated gravel and MTB use should look at the Favero Assioma PRO MX-2. Riders on a budget will find the Magene PES P515 crankset hard to beat on price-to-performance, and the Favero Assioma Uno remains the cheapest legitimate entry into pedal-based power.
The right power meter for your gravel bike comes down to how many bikes you ride, what cleats you use, and whether you want to train indoors as well. Whichever meter you choose from this list, you will get ±1% accuracy, ANT+ and Bluetooth connectivity, and the data you need to pace long events, track fitness, and structure your training in 2026 and beyond.
