    v2 VBC 2x Chainring Sets

    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.

     

  • VBC v2 Outer Chainrings

    VBC v2 Outer Chainrings

    The V2 VBC (Variable Bolt Circle) outer chainring is designed for 2x 12-speed compatibility across Shimano and SRAM 9–12 speed drivetrains. That includes Shimano 105, Ultegra, GRX, and Dura-Ace (9–12 speed), as well as SRAM Apex, Rival, and Red (10–12 speed), in both mechanical and electronic configurations.

    The Variable Bolt Circle design allows up to five different inner ring sizes to be mounted to the same outer ring, offering flexible gearing without replacing your entire setup. Across the range, that provides up to 33 possible gear combinations depending on your pairing.

    The V2 outer ring has been completely redesigned with updated tooth profiles and revised shift ramp geometry for smoother front shifting. It features five integrated shift pins, a replaceable chain catch pin, and recessed inner chainring bolts for improved chainstay clearance and a clean interface.

    Like all V2 VBC components, it remains fully backwards compatible with White Industries MR30 series cranks and White Industries direct mount square taper cranks, however it is not compatible V1 inner rings. For a complete set you will need a V2 inner ring and hardware. 

    Available in black and silver.

    The V2 VBC (Variable Bolt Circle) inner chainring is designed for Shimano and SRAM 9–12 speed 2x drivetrains, including Shimano 105, Ultegra, GRX, and Dura-Ace (9–12 speed) and SRAM Apex, Rival, and Red (10–12 speed), in both mechanical and electronic configurations.

    As part of the VBC system, this inner ring mounts to a compatible VBC outer ring, allowing multiple inner ring sizes to be used with the same outer ring. The system supports up to five different inner ring sizes and offers as many as 33 possible gear combinations across the range.

    The V2 inner ring has been completely redesigned with updated tooth profiles and shift ramp geometry for improved shifting performance. It features refined machining details to work seamlessly with the V2 outer ring, including compatibility with five shift pins and a replaceable chain catch pin when paired as a complete set.

    Like all V2 VBC components, this inner chainring is backwards compatible with all White Industries MR30 series cranks and White Industries direct mount square taper cranks, however it is not compatible V1 outer rings. For a complete set you will need a V2 outer ring and hardware.

  • MR30 TSR 1x Chainrings

    MR30 TSR 1x Chainrings

    Product details

    TSR (Tall-Short-Ring) 1X chainrings are designed to work with 8-12 speed 1X drivetrain systems.  The tall/short tooth profile helps prevent the chain from falling off the ring when riding through rough terrain and is a must on 1x drivetrains, but is also compatible with singlespeed drivetrains. Made in our shop from 7075-T6 aluminum (48-52 tooth rings are 6061-T6).

     

  • VBC 2x Chainring Hardware Sets

    VBC 2x Chainring Hardware Sets

    These hardware sets are needed to mount VBC 2x chainrings to outer VBC 2x chainrings.  If you are purchasing a VBC chainring “set” the hardware is already included and the rings will be assembled together.  There are two types of VBC 2x chainrings, v1 for the older 9-11 speed rings, and v2 for the new 9-12 speed rings.  Refer to the tech docs below for information on how to identify which version rings you have and installation instructions.

    You would need a hardware set if:

    1. You are purchasing separate VBC 2x inner and outer rings
      1. You need this hardware to bolt the rings together
    2. You lost some of your hardware when working on your bike
    3. Some other odd reason we’re not aware of
  • M30 Mountain Cranks

    M30 Mountain Cranks

    Product description

    The best way to describe this model is, “It’s a White Industries mountain bike crank”.  Simple.  The M30 is a direct replacement for most mountain cranks from the big “S” companies, but with a lot more options: two crank arm colors, eight extractor cap colors, three 1x chainlines, a 2x chainring option, and seven crank arm lengths.  Like we said, options!  Check out the comprehensive information below for all the details you’ll need to help navigate to the correct set up for your bike.

     

  • A30 Adventure Cranks

    A30 Adventure Cranks

    Product description

    The A30 is part of our 30mm spindle line of cranks which also includes the M30, R30 and G30 models.  The “A” stands for adventure and the “30” is for the 30mm spindle.  Made here in our shop, the A30 draws on over 30 years of crank manufacturing experience with a focus on all the White Industries hallmarks; functionality, durability, and clean design.  The best way to describe this model is, “kind of odd and probably not going to fit your bike.”  So read all the info below before you purchase….

    The A30 combines our R30 road crank arms with our M30 mountain spindle to give you an odd mix of a mountain chainline with narrower crank arms that will not fit on a mountain bike.  So what bikes will this fit, and why would I need it?  There are some gravel frames out there (mostly custom made) with 73mm wide bottom bracket shells that require a longer spindle than the R30 or G30 crank has, but also have narrower chainstays that don’t need the wider crank arm stance of the M30 crank.   That’s where the A30 comes in.  Think of it as a mountain crank with a slimmer Q factor.  They come in two crank arm colors, eight extractor cap colors, three 1x chainlines, a 2x chainring option, and six crank arm lengths.  Check out the comprehensive information below for all the details you’ll need to help navigate to the correct set up for your bike.

    The R30 is part of our 30mm spindle line of cranks which also includes the M30, A30 and G30 models.  The “R” stands for road and the “30” is for the 30mm spindle.  Made here in Petaluma, the R30 draws on over 30 years of crank manufacturing experience with a focus on all the White Industries hallmarks; functionality, durability, and clean design.  The best way to describe this model is, “It’s a White Industries road bike crank”.  Simple.

    The R30 is a direct replacement for most road and gravel cranks from the big “S” companies, but with a lot more options: two crank arm colors, eight extractor cap colors, three 1x chainlines, a 2x chainring option, and six crank arm lengths.  Like we said, options!  Check out the comprehensive information below for all the details you’ll need to help navigate to the correct set up for your bike.
