Pedal-based power meters eliminate the compatibility headaches that come with crank-based systems, and the SRM X-Power MTB brings that convenience to off-road riding with full Shimano SPD cleat compatibility. SRM houses all the electronics and rechargeable batteries inside the pedal spindle rather than in an external pod, which keeps the stack height at 10.5mm and the Q-factor at 54mm. Those numbers match a standard SPD pedal, so there's no change to your pedaling position when switching from conventional pedals. If you're running power on multiple bikes, the pedal format lets you swap your meter between them in minutes with just a pedal wrench.

The X-Power uses Look-supplied retention clips that accept standard 2-bolt SPD cleats, giving you the mud-shedding capability and walkability you need for gravel, cyclocross, and mountain bike applications. The enlarged pedal platform provides solid support under foot with a larger contact area for shoe tread blocks compared to earlier designs. Tension is adjustable to match your preferred release force, and if you damage a pedal body in a crash or rock strike, the modular system allows you to swap just the body without replacing the entire power meter spindle. That's a meaningful consideration given how often MTB pedals take hits on technical terrain.

Construction combines an anodized aluminum pedal body with a coated stainless steel spindle that resists corrosion from mud, water, and trail spray. Three internal bearings handle the rotation while high-quality sealing keeps moisture out of the electronics compartment. The magnetic charger connection sits behind the spindle threads where it stays protected from impacts, and SRM rates battery life at 30 hours per charge via the included USB cables. The internal battery does draw standby power at roughly 5 percent per day, so plan on charging every couple of weeks even if you're not riding frequently.... Read More
