E13 e*spec Race Carbon Crank, Bosch CX G4

We′re now 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. e*spec cranks have an 8mm self-extractor built in to both arms for easy removal.
