The AX-Lightness PELTON ROAD crank is forged aluminum crank with a shaft diameter of 30 mm, suitable for the bottom bracket standards of BSA, BB30, BB386, BB386evo and BBright.

The crank lengths are initially limited to 172.5 mm and 175 mm. Bottom bracket are not included. The battery life is 1,400 hours.
