Surly Stainless Steel Inner Chainrings for customizing a Mr. Whirly Offset Double (MWOD) crankset.
  • Bolts directly to an outer MWOD chainring using a specialy designed secondary bolt circle
  • MWOD inner and outer chainring combo bolts directly to the 58mm BCD mounting holes on Mr. Whirly cranks
  • Converts the Mr. Whirly crankset into an offset mountain double crank which allows for extra wide rear tire and rim combinations while avoiding chain-on-tire rub, e.g., 4.7" tires on 82mm or 100mm rims
