Chainring Set 20/33T MWOD (CR5884)

Increase your tire footprint by going MWOD. Truly a Surly original.
  • The two rings are bolted to each other; the combo then bolts directly to the 58mm bolt circle on Mr. Whirly cranks (hardware included)
  • 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
  • Smaller rings are stainless steel; bigger rings are aluminum
  • Granny and middle rings are repositioned to the outer two spots on the crank. This increases tire clearance at the chain without increasing Q-Factor or sacrificing the essential lower gears
  • MWOD = Mr. Whirly Offset Double
