Surly's Mr. Whirly Offset Double Crankset is designed specifically for bikes running very large tires and rims, such as Surly's Moonlander and/or Pugsley. The offset ensures that the chain will never rub on the tire. Mr. Whirly is made of forged and machined 7075 aluminum, is 9-speed compatible and comes with 22- and 36-tooth 5-bolt/5-arm chainrings. It also has a bash guard and comes with a precision English-thread sealed-bearing bottom bracket (fits 100mm-wide frame bottom brackets), so this trick crankset is ready for installation.
