Stiff, forged and hollow-bored, the power2max by Rotor crank arms are the base for a power2max spider that keeps your Shimano Dura-Ace, Ultegra or 105 4-arm chainrings.

Compatibility & fit

Developed for the Shimano Hollowtech II bottom bracket standard; the 24mm steel spindle replaces current Shimano road cranks without special tools. Compatible bottom brackets: BB86, BB90, BSA68, ITA70, BB30, PF30, T47, BBRIGHT and Shimano Pressfit. Combine with a power2max 110 4-S or 4-SL power meter (not included) to keep Shimano Dura-Ace, Ultegra or 105 4-arm chainrings and their shifting. The distributor supplies these crank arms only with a power2max power meter, so order them together with your power meter spider. Our workshop can fit the cranks, bottom bracket and power meter as a separate service, not included in the price.

power2max parts and accessories are covered by the manufacturer's warranty against defects in materials and workmanship. For warranty support, return the product to Tune Cycles and we'll manage the claim with power2max's Australian distributor.
