This chain ring is designed to be used as part of the White Industries Variable Bolt Circle (VBC) bicycle crankset. The VBC is a double rather than a triple ring crankset because a traditional triple tends to have a lot of unnecessary gear overlap. The VBC crank is cleaner and less complex and still gives the rider suitable gearing solutions. White Industries offers a large range of gearing options and the rings can be mixed and matched to whatever combination suits your bike and riding needs.
This outer ring has a unique design with a splined ring interfacing to the crank set. An elongated five-window design replaces the more traditional chain ring bolt circle, and these windows allow the inner ring to self center without being confined to a specific bolt circle.
All VBC chain rings are hard black anodized, ramped and pinned.
This chain ring is designed for use only with the White Industries VBC (variable bolt circle) crankset.
