JT Nebekerwrote a review of Stages Cycling Gen 2 Shimano XTR M9020 Trail Single Leg Power Meter Crank Arm on September 21, 2018
Familiarity: I've used it several times
The most cost-effective solution to running a power meter on your mountain bike. It’s single leg, so you don’t get the specific Left/Right data, but for power-based training and understanding what’s happening during your race run, it works perfectly. Must have for the dataset heads.
