White Industries VBC Chainrings

VBC17 Chainrings

 

The VBC17 is White Industries highly adaptable 2x chain ring set up for square taper cranks. VBC stands for Variable Bolt Circle which is what makes this chain ring design so unique. The Variable Bolt Circle is achieved by having slots on the outer chain ring so the bolts and ramps can slide along them allowing almost any VBC inner chain ring to attach to the outer ring (see the recommendations below). With an outer gear that ranges from 38-52 in even tooth increments, and an inner that ranges from 24-38 in even tooth increments, this chain ring set can be customized to whatever gear ratio works for you. Whether you are in the hills or riding the flats the VBC rings can be fitted to your perfect gear ratio’s
