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 the MG30 or R30 crankset and both 11 or 12sp cassettes (with the exception of new SRAM AXS 12sp which is not compatible). Also available for ENO / VBC Square Taper cranks.
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. **
