The Stages Power Dura-Ace Track is the power meter option for track riders who are looking to add power to their existing crank. The Stages Power is pre-assembled on Dura-Ace Track left crankarm. It replaces the existing left crankarm which makes installation pretty simple. Riders only need to select length as the Stages Power meter fits all Dura-Ace FC-7710 cranks.
Via ANT+ and Bluetooth Smart technologies the Stages Power is compatible with all ANT+ cycling computers as well as with the latest smartphone models.
