Smooth-pedaling ergonomics in an extra-burly eMTB build.

Our Aeffect R eMTB cranks bring the burly, purpose-driven design of Aeffect R to the Bosch Gen4 drive system. While they are designed for rowdy, power-down riding, the 444g weight puts them among the lightest alloy eMTB cranks on the market. Pair with a Steel DM Bosch G4 ring for the perfect integrated styling.
