Stages Durace 9100 power meter

Non-Drive Side Powermeter Crank Arm
This is the single-sided Stages Power L (left-side) meter built on to a non-drive-side Shimano Dura-Ace R9100 crank arm and is compatible with all frames that fit Shimano Hollowtech II cranks. This new meter is founded on Stages Power technology, including Stages’ defining Active Temperature Compensation feature in a package that offers the most technical cyclist the data they crave. When combined with the Stages Performance Ecosystem of Stages Link and Dash, Stages Power L gives additional data that the most advanced cyclists need to bring out their best performance. The purchase of a Stages Power meter includes free lifetime access to Stages LINK for power meter management and firmware updates.
