The Crank Arm Bolts are included.
These VBC Road Cranks are an integral part of the White Industries Variable Bolt Circle (VBC) drive train systems. The VBC Road Crank is designed to sit close to the chain stays to transfer more direct power into each pedal stroke. 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.
These White Industries cranks 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.
The VBC (Variable Bolt Circle) crank set is designed as a traditional double ring crank set, and can also be paired with the single speed chain rings and set up as a single ring set. The innovative design of the outer ring includes a splined ring interfacing to the crank set, and the ring has an elongated five window design replacing the more traditional chain ring bolt circle. These windows are both unique and versatile, and allow the inner ring to self-center without being confined to a specific bolt circle. The chain rings are machined out of 7075, hard black anodized, and ramped and pinned for maximum shifting efficiency.
Please Note: These Cranks are only compatible with White Industries Chain Rings.
