VBC v2 Outer Chainrings

The White Industries V2 VBC Outer Chainring is a precision-machined chainring designed for Shimano and SRAM 2x road and gravel drivetrains. We machine, finish, and inspect every chainring in our Petaluma, California facility. As a result, the V2 VBC Outer Chainring delivers crisp shifting, exceptional durability, and premium American craftsmanship. The V2 VBC Outer Chainring is part of the White Industries Variable Bolt Circle (VBC) system. It is compatible with Shimano 9-12 speed drivetrains, including 105, Ultegra, GRX, and Dura-Ace, as well as SRAM 10-12 speed Apex, Rival, and Red groupsets. It works seamlessly with both mechanical and electronic shifting systems, making it an excellent choice for modern road and gravel bikes. The Variable Bolt Circle design provides unmatched gearing flexibility. Therefore, you can pair a single outer chainring with up to five different V2 inner chainring sizes. With as many as 33 possible gearing combinations, the VBC system allows you to fine-tune your drivetrain for racing, climbing, endurance rides, or mixed-surface adventures without replacing your entire chainring setup. The V2 Outer Chainring has been completely redesigned for improved shifting performance. It features optimized tooth profiles, revised shift ramp geometry, five precision shift pins, a replaceable chain catch pin, and recessed inner chainring bolts for improved chainstay clearance and a clean, integrated appearance. Together, these refinements deliver faster, smoother, and more reliable front shifting. The V2 VBC Outer Chainring remains backward compatible with all White Industries MR30 Series cranks and White Industries direct-mount square taper cranks. However, it is only compatible with V2 VBC Inner Chainrings. For proper installation, pair it with a V2 VBC Inner Chainring and the appropriate V2 hardware. Available in black and silver.
