Stages Power meter | XTR M980/985 Double

Availability: Ships 1-2 days

For mountain bike riders we offer a Stages Power meter available as a power meter only non-drive crank arm for existing Shimano M985 model (double) or M980 (triple/double) cranks. Riders looking to add power to their existing crank need only select the applicable XTR model and length to fit their needs.
The new Stages Power meter is slimmer, and up to 28-percent lower profile than our original meter. It's sleeker by way of a 17-percent reduction in frontal area, and we've also made it stronger. The new housing design increases the strength of the battery door and housing connection by 200-percent over the previous design.
