Power2Max Crank Arms - ROTOR ALDHU-R 24 Crank Arms + 24mm Spindle

**ITEM MUST BE PURCHASED WITH POWER2MAX POWER METER**

The Rotor ALDHU-R 24 crank arms with 24mm steel axle allow compatibility for bikes with Shimano bottom bracket, and consists of the NG Powermeter Spider and the Rotor ALDHU-R 24 crankset with 24mm steel axle. 

When combined with a suitable Power2Max power meter, the Powermeter allows a Shimano-Ultegra or DuraAce user to upgrade to a completely dual-sided power measurement, while retaining the shifting benefits of their existing Shimano chainrings.

The Rotor ALDHU-R crank is compatible with the Shimano Hollowtech II bearing standard and makes a replacement of the bottom bracket unnecessary.
