Description

These are the inner VBC (Variable Bolt Circle) chainrings and will fit either style of outer VBC rings for the M/A/R/G 30 cranks or ENO/Square Taper Road cranks.

When Doug saw the limitations presented by all the different bolt-circle diameters required to manufacture chainrings, he figured there had to be a better way. “Hey, how about no standard?”, and the VBC chainring system was born. VBC stands for “Variable Bolt Circle” and replaces several different bolt patterns with one simple, slotted outer chainring design that accepts a wide range of our inner VBC chainrings. The outer chainring mounts directly to the crank and serves as the mounting point for the inner chainring

. As bikes, drivetrains, and riding styles have changed in the last decade, the VBC system has found a following among riders tired of being told what gear ratios they should be using. Available in 39 “recommended” combinations, there’s no other system that allows this level of customization!
