Stages Cycling Stages Power Meter Shimano Dura Ace 7900 - left Crank Arm
Details
For Dura-Ace 7900 riders we offer a Stages Power meter as a replacement for existing 7900 non-drive crank arms. Riders looking to add power to their existing crank need only select length, as the Stages Power meter (Dura-Ace 7900) fits all styles of 7900 crankset, including: compact and standard. For those riders looking to replace an entire existing crankset should look to the Shimano Dura-Ace 9000 model, which works with existing Dura-Ace 7900 mechanical and Di2 electronic 10-speed group sets; a CN-9000 chain is recommended.
