The SRM X-Power Road pedals deliver class-leading power measurement accuracy, maximum flexibility, and seamless integration. The electronics are housed inside the pedal spindle, so the pedal's slim silhouette mirrors the Stack Height and Q-factor dimensions of a standard SPD-SL compatible pedal. And that means power measurement without the heft and height compromises that come with typical power pedals.

This is the dual-leg power measurement version of the pedals (they also come in single-leg versions). Some cranks (e.g., SRAM or 3T) are very thin and expose the pedal threads and end cap. If you use a crank with less than 13 mm of threading, please choose the Short Spindle version.
