Upgrade or replace your e-bike crank arms with the Samox E3 BR Crank Arm Set. Engineered explicitly for Specialized full-power Turbo e-bikes, this crankset offers an exact match for the precise frame offsets and Q-factor requirements of Brose-powered motor systems.

Available in shorter 155mm, 160mm, and 165mm lengths, these arms are a highly sought-after geometry upgrade for e-mountain bikes (eMTBs) to drastically reduce pedal and crank strikes on technical, rocky climbs.

155mm: Maximum clearance to eliminate pedal strikes on highly technical, rocky terrain.
160mm: Great balance of technical ground clearance and standard pedaling leverage.
165mm: Traditional shorter configuration providing comfortable ergonomics and a natural cadence.
