Offset
All sizes use a 0mm offset.
The 46/32T has a 2mm inner offset, which becomes 0mm once the two included spacers are installed with the chainring.
Important Notice
Decorative bolt sets fit STONE 2X chainrings only and cannot be used with other brands.
46T / 32T cannot use decorative bolts, because the 32T chainring uses a built-in female bolt structure.
If you choose a chainring larger than 54T or smaller than 48T, you may need a front derailleur extender to adjust the derailleur height.
