Race Face Aeffect E-Bike Crank Arms

Hearing the increasing popularity of e-bikes, Race Face has answered the call by modifying our rock solid Aeffect crank arm specifically for e-bike. With increased clearance, while optimizing Q-factor, and a redesigned spline interface to maximize strength. The new Aeffect E-bike Crank is the perfect upgrade for the more discerning e-bike rider.


  • Forged/CNC machined 6066 aluminum arms specfically for E-Bikes
  • Cinch system 24mm spindle, offering the same modular design as Cinch 30mm cranks, meaning a wider 24mm spindle can swapped out later for non-FatBike use

  • Interface (BB): Cinch-24mm
