Race Face Aeffect eMTB 170mm Crankarm Black

Strong Stuff. We made the Aeffect arms from net forged 6066 alloy because we knew they are going to have to stand up to big trail days and sick drops – ebike style.

Know Your Q-Factor. EBikes require wider Q-factors than regular bike so we adjusted Aeffect eBike crankarms to leave just the right amount of clearance for Bosch motors.

Three Is The Magic Number. To fit the more riders and more rides, these crankarms come in the three different length options, including 165mm.

The ebike army asked for it and Race Face delivered. Introducing our fan favorite Aeffect crankarms re-configured and optimized to fit the specific needs of ebike shredders everywhere. 

These cranks are designed for ebikes only.
