Product Description

For riders looking to add a complete power system to their existing frames, Stages Cycling offers the Shimano Dura-Ace 7900 crank arm. Measuring power from the non-drive side crank arm, Stages power meters allow riders to select either a standard (39/53-tooth), mid-compact (36/52t), or compact (34/50-tooth) crankset.

The Stages Power Shimano Dura-Ace 7900 model is cross-compatible with all Shimano Hollowtech II road models, from Tiagra to Dura-Ace 9000. The technology is the same that’s found on all Stages Power meters, and as used by Team Sky. It weighs only 8 grams more than the Stages Power Shimano Dura-Ace 9000 model, and is 22 grams less than the Stages Power Shimano Ultegra 6800 model (average weights/actual difference may vary).
