Surly Aluminum Chainring 33t MWOD Outer. Surly aluminum outer chainrings for customizing a Mr. Whirly Offset Double (MWOD) crankset.
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
Outer chainrings bolt directly to MWOD inner rings with 4 chainring bolts
Inner BCD (for mounting to granny ring) is proprietary; outer BCD (for bashguard) is 104mm
