Show Description

Cyclists looking to make serious gains will appreciate the consistency and accuracy of this dual-sided power meter. Based on the latest Dura-Ace R9100 crankset, the Stages Dual-Sided power meter allows for independent measurment of a rider's left and right legs, measures pedal smoothness and, most importantly, helps you reach your goals.

This unit is as low-profile and lightweight as a power meter gets – 35g – with a minimalist housing and sleek front profile. You can expect wattage readings to be accurate within 1%. ANT+ and Bluetooth Smart compatibility makes it good to go with pretty much any major GPS or cycling computer on the planet. The compact, easy to source, coin cell battery's life is over 175 hours, and you can swap it out yourself.
