We're bringing our World Cup proven technology to the eBike marketplace, with our e*spec Race Carbon Cranks.
In contrast to our Gen3 carbon cranks, the Q Factor, overall profile, and volume of our Gen4 cranks has been greatly reduced. Bosch®, Brose®, TQ®, Fazua® e*spec cranks have an 8mm self-extractor built in to both arms for easy removal of press-fit versions. Shimano EP8 Cranks are compatible with EP8, EP800, and E8000/7000 motor systems. E8000/7000 require adapter kit CSS30-114. They're designed with a lightweight single bolt spindle clamp and alloy preload caps, with crank boots for added impact resistance.
Available for Bosch Gen4 CX, Brose S Mag drive, Fazua Ride 50, TQ and Shimano EP8.
