Forged aluminium

Prowheel forges the EB03 from AL6061-T6 aluminium and lists it in its Bosch e-bike range with a 27.5mm offset and a 188mm Q-factor.

Compatibility & fit

Prowheel lists the EB03 for Bosch Active Line and Performance Line CX drive units with an ISIS spindle interface. Check your drive unit and the length of your current arms before ordering. Each arm is a separate option, so order a left, a right or both. Fitting is a separate workshop service and isn't included; our Marrickville workshop can fit e-bike cranks for you.
