The White Industries MR30 VBC Chainrings: VBC is an acronym for Variable Bolt Circle. The beauty of VBC rings is they allow you to set up various tooth configurations to get the gear ratio you desire. The outer ring is designed with a slotted section and the inner five bolt ring is self-centering, allowing more options when compared to traditional crank designs with set bolt circle requirements. White Industries recommend at least a ten tooth difference between the outer gear and the inner gear and a 20 tooth on the high end, but the maximum is 24 teeth. The VBC rings can be configured with an off road ratio and mated to your mountain bike uses the ENO crank arms, or, if you have a road frame, use the VBC road crank arms and configure a suitable ratio for road riding. It is Compatible with 9 10 and 11 speed. The VBC system is designed with the simple thought that not every person or place falls under the same gearing. With that thought in mind, White Industries have created a chainring system that allows you to customize your gearing to make sure you get the most enjoyable ride possible. Inner ring: 24- 38 even increments, Outer ring: 38-52 even increments. Recommended at least a 10 tooth differential between the inner and outer ring and a maximum difference of 24 teeth. VBC Bolts included with Double Rings. Made in the USA.
