The VBC (variable bolt circle), road crank set is both an elegant and durable addition to your road bike. The crank set is designed as a traditional double ring crank set, however, it can also be paired with one of White Industries single speed chain rings, and be set up as a 1x.
The crank is designed with a low Q factor, 150mm, that allows the arms to sit close to the chain stays, effectively giving you more direct power transfer with each pedal stroke. The outer ring is an innovative design, with a splined ring interfacing to the crank set. Engineered into the ring design is an elongated five window design that replaces the traditional chain ring bolt circle. The windows are ingeniously unique and versatile allowing the inner ring to self centre without being confined to a specific bolt circle.
The chain rings are machined out of 7075, hard black anodized, and are ramped and pinned for maximum shifting efficiency. In addition, the road crank arms can be mated to the ENO single speed rings for a 1x road bike option. Made in the USA.
