Aeffect R eMTB brings the burly, purpose-driven design of Aeffect R to light-assist and full-power e-bikes. They're built for rowdy, power-down riding, yet at 485g Race Face puts them among the lightest alloy eMTB cranks on the market.

Highlights

• 7050 aluminium arms built for the loads of full-power e-bikes
• 485g (165mm arms only)
• 160, 165 and 170mm lengths, trimmed for better rock and root clearance on the shorter sizes
• Smooth-pedalling ergonomics in an extra-burly eMTB build
• Lifetime Warranty, crashes included
• ETOR motor interface: for Fazua Ride 60 (not Fazua Ride 50)

Ground control

Dial in your fit with 160, 165 or 170mm arms. The shorter sizes are trimmed to length for better clearance over rocks and roots, so you clip fewer pedals on technical climbs.

Built for e-bike loads

Race Face builds Aeffect R eMTB for the compatibility constraints and higher forces of full-power e-bikes, and covers it with its Lifetime Warranty, crashes included.

Compatibility & fit

Race Face's Aeffect R eMTB crank-motor compatibility chart lists this ETOR version as compatible with Fazua Ride 60. It isn't compatible with Fazua Ride 50 and non-ETOR drive units.

Chainrings aren't included. Crank fitting is a separate workshop service at Tune Cycles; tell us your bike and drive unit and we'll confirm the right interface before you order.
