White Industries VBC Outer MR30 Chainring 485-336

The outer VBC (Variable Bolt Circle) chainring is innovative in design.  This particular option has is for use with White Industries MR30 cranksets.  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-center without being confined to a specific bolt circle.

They are CNC machined out of 7075 aluminum, hard anodized black and are ramped and pinned for maximum shifting efficiency.

This chainring attaches directly to the crankarm. VBC inner chainring and chainring bolts are sold separately, allow you to customize your crankset to exacting standards!

All always, these White Industries bits and lovingly machined in Petaluma, California in good ol' the U.S of A.
