Crank Arm Bolts are included.
These ENO bicycle Crank Arms are an integral part of the White Industries drive train systems.
They are machined out of billet aluminum, and use a rigid box shaped crank design, creating a crank that is extremely stiff and yet light weight. This box design allows power to be transferred directly into the bike crank arms rather than dissipated and lost as with a more flexible, less rigid crank design.
White Industries also feature the spline interface between the chain ring and the crank arm. A simple lock ring holds the ring in place making the cranks versatile for multiple gear ratios.
Please Note: These Crank Arms are only compatible with White Industries Chain Rings.
