Increase your tire footprint by going MWOD. Truly a Surly original.
MWOD = Mr. Whirly Offset Double
These chainrings convert your Mr. Whirly crankset into an offset mountain double crank, allowing you to run extra wide rear tire and rim combinations (4.7" tires on 100mm rims, for example, or 82mm rims on your Pugsley) while avoiding chain-on-tire rub
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
The two rings are bolted to each other; the combo then bolts directly to the 58mm bolt circle on Mr. Whirly cranks (hardware included)
