Favero Assioma PRO MX-1

A rugged, SPD®-compatible power meter purpose-built for MTB and gravel. The PRO MX-1 measures power on the left pedal only and delivers Favero’s ±1% accuracy, advanced cycling metrics, and a low 11.2 mm stack height, ideal for technical trails and hot desert rides. Upgradeable anytime to dual-sided with the MX-UP kit.
