Race Face Aeffect R E-MTB Crankarm

Race Face responds to the growing demand for e-MTBs with the Aeffect E-MTB crank arm, specifically designed for the Bosch Gen4 drive system. This crank arm combines the robust design of the Aeffect R with the requirements of an e-MTB crank. The optimized 180 mm Q-factor provides ample clearance, ensuring perfect ergonomics and a riding feel similar to that of a standard Race Face MTB crank. With crank lengths of 160/165/170 mm, it offers increased ground clearance while pedaling, allowing for valuable millimeters of space and helping to prevent falls. Although the Aeffect R E-MTB is designed for rough rides under full load, it is one of the lightest e-MTB aluminum cranks on the market, weighing in at just 444 g.
