The Sigeyi power meter measures power from both legs, is accurate to +/- 1.0% and is lightweight at only 105 grams. In addition, it easily bolts up to your existing Easton crankset. Therefore, there is no need to buy new cranks or replace your bottom bracket.

GoRide (verified owner) –
Excellent customer service and advice on a Sigeyi PM for Easton EC90 SL cranks (Cinch system, the parktool BBT-22, 20-spline, is the right tool) on gravel bike, super easy install and setup. So far so good with this Sigeyi PM, has great features and is as accurate as claimed. Thanks PMC for the detailed advice and double checking compatibility for parts i ordered, they even pre-assembled and torqued it. Rare customer service in today’s market place.
