SPD power meter pedals for gravel: Favero, Garmin, Look and SRM compared

Disclosure: Pedal Brief may earn a commission if you buy through links on this page, at no extra cost to you. This version has no affiliate links. We have not tested these pedals ourselves. Every spec and price below comes from the brand's own pages unless we say otherwise, and each is linked. Full disclosures.

Who it's for: gravel riders who use two-bolt SPD shoes and want power data they can move between bikes, without changing their cleats or walking shoes.

This guide compares four SPD-compatible power meter pedals from Favero, Garmin, Look and SRM. There are other brands we have not covered. All four are rechargeable and all four come in single-sided and dual-sided versions. The real differences are battery life, how they charge, stack height, whether the sensor can move to road pedal bodies, and price.

A note on names. Favero's current model is the Assioma PRO MX-2, which is what "Assioma MX-2" now refers to on Favero's store. Garmin's current off-road pedals are the Rally XC110 and XC210, announced in September 2025. The older Rally XC100 and XC200 use coin-cell batteries, and we cover them separately below.

For how SPD, SPD-SL and the new SPD-SLR relate (bolt patterns and which cleats fit which pedals), see our Shimano SPD vs SPD-SL vs SPD-SLR explainer.

Battery and charging

Favero. Favero says the PRO line has "the longest battery life among pedal-based power meters, with up to 160 hours of use per charge". That figure came from a firmware update in February 2026, which DC Rainmaker reports raised the claim from 60 to 160 hours. Older Favero spec sheets still say "at least 60 hours", so update the firmware before judging the battery. Charging is magnetic, both pedals charge at the same time, and Favero claims "15 hrs in 15 m".

Garmin. The Rally 110/210 pedals are rechargeable, rated at up to 90 hours, and Garmin says a 15-minute charge gives up to 12 hours. Each pedal charges through its own clip and USB-C cable. The owner's manual recommends a USB-C port or adapter rated for 2 to 2.5 W, and no wall adapter comes in the box. On the single-sided XC110, only the left pedal needs charging. A Travel Mode switches the pedals off for transport.

Look. Look rates the X-Track Power at 60 hours in use, six months in sleep mode and more than 12 months in deep sleep, from a 140 mAh Li-Po battery in each axle. Both pedals charge together through a magnetic connector and USB-C cable. Look also claims "less than 20% capacity loss after 300 full cycles (approx. 10 years of use)".

SRM. SRM lists up to 30 hours of runtime from a 70 mAh lithium polymer battery, charged by a magnetic charger. That is the shortest runtime here by a wide margin. SRM's 2022 manual lists a micro-USB cable and adapter in the box, and says a full charge takes about three hours. We could not confirm whether current units ship with USB-C.

Older Garmin XC200/XC100. These are not rechargeable. Garmin's Rally specifications list user-replaceable batteries (one CR1/3N or two LR44/SR44 per pedal) and up to 120 hours with cycling dynamics. If you find a discounted XC200, you are buying into coin cells rather than a charger. Garmin does not state battery prices, so we have not estimated the running cost.

Cleat compatibility

All four use two-bolt SPD-style cleats, so your existing SPD shoes will work. The details differ:

If you ride road as well, Favero and Garmin both sell road pedal bodies for their off-road power pedals. Favero sells road bodies for the same spindle at $130 a pair (RS for Shimano SPD-SL cleats, RL for Look Keo) and says the swap needs no adapters or special tools. Favero lists the pair as "1x left pedal body" and "1x right pedal body", with no cleats listed. Garmin sells a Pedal Body Conversion Kit at $149.99 for RS (SPD-SL) and $249.99 for XC. The RK (Look Keo) version is listed but showed no price when we checked. Garmin lists the contents as "Two Rally™ RK/RS/XC pedal bodies (depending on the version selected), Cleats, Hardware, Documentation". Garmin also sells bundles pairing a dual road set with XC bodies. Look lists its Instrumented Power Axle at $450 per side as "Compatible with Keo Blade Power and X-Track Power", and its power accessories page lists Keo Blade Power bodies at $125 per side. The Look pages we checked do not describe how to move an axle from one body to another. SRM does not describe a road swap on its product pages. Prices checked 26 September 2026.

Single vs dual sided

Single-sided pedals measure one leg and double it. Dual-sided pedals measure both legs, which gives real left/right balance and more pedalling metrics.

If you only want training zones, single-sided is the cheaper route in all four ranges. If left/right balance matters to you, for example after an injury, buy dual from the start unless you have checked the upgrade price.

Running costs (brand-stated prices only)

The ongoing costs are cleats, plus chargers or cables if you lose them. What the brands list:

Weight and warranty

The brands state weight differently, so compare with care. Favero lists 199 g per pedal. Look lists 202 g per pedal, 404 g a pair and 455 g a pair with cleats. Garmin lists 436 g for the XC210 without saying whether that includes cleats. SRM's shop says 194 g and SRM USA says 172 g per pedal. Warranty is 2 years for Favero and SRM, per their shop pages, and "up to 3 years" for Look. We did not find Garmin's warranty term on the product page.

Which one fits

For road pedals, crank arm, spindle and spider meters, see our best-value power meters guide.

If you are building up a gravel bike at the same time, our gravel tire pressure guide and gravel tire clearance chart cover the other two questions that come up most.
