Product Details

Released in April of 2025, our new v2 VBC (Variable Bolt Circle) 2x 12-speed compatible chainrings are compatible with Shimano and SRAM 9-12 speed 2x drivetrains. That includes Shimano 9-12 speed 105/Ultegra/GRX/Dura Ace and 10-12 speed SRAM Apex/Rival/Red, in either mechanical or electronic versions. They retain the Variable Bolt Circle feature that allows up to five different size inner rings to be mounted on the same outer ring, with 33 possible gear combinations across the range. And as we always strive for when designing new products, they are backwards compatible with all White Industries MR30 series cranks and White Industries direct mount square taper cranks.

V2 VBC 2x inner rings, outer rings, and hardware are completely redesigned and feature revised outer chainring tooth and shift ramp geometry, five shift pins, a replaceable chain catch pin, and recessed inner chainring bolts. And now you can get them in black and silver, not to mention seven different colors of chainring nuts so you can really tie the room together. To sum it all up: 9-speed to 12-speed compatibility, backwards compatibility with our cranks, more chainstay clearance, 33 gear combinations, and more color choices.

Our old 9-11 speed VBC 2x chainrings will now be referred to as “v1 VBC 2x chainrings” and will be discontinued as of April 22, 2025. Remaining stock will be available on our website until we run out, but we will continue stocking hardware for v1 VBC 2x chainrings indefinitely. So what do you do when you can’t get v1 rings anymore? Just get a v2 VBC 2x chainring set; they’ll work with whatever set up you already have.
