{"id":1818931724354,"title":"White Industries Variable Bolt Circle (VBC) Double Chainring","handle":"white-industries-variable-bolt-circle-vbc-chainrings","description":"

VBC is an acronym for Variable Bolt Circle. It provides arguably the most flexible double chainring on the market with a huge range of chainring sizes from 24x38 all the way through to 38x52 ratios.

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.

We 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 on your mountain bike or a more traditional road set up.

Compatible with 9, 10 and 11 speed Drivetrains only.

Outer Ring: 38-52 even increments.
Inner Ring: 24- 38 even increments.
Color: Black Only.
Crank Type For Outer Ring Only: MR30 (also includes G30) or Square Taper (ENO or VBC).

** Please note, if you are buying a set of 2 x chainrings you need to select each size individually and add each to the basket separately. Plus you will need to also check the box to add chainring bolts. **
