Stages Left Side Power Meter Shimano DURA-ACE 9100

The single-sided Stages Power L (left-side) meter is 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.

THE SCIENCE OF STAGES
Stages power meter is: Downright miniature. Under 20g. Made from the same material as bullet proof glass. Simply put, the Stages Power meter sports the most advanced technology employed in the power meter category, all while being one of the easiest to maintain and simplest to use.
