Surly Mr. Whirly Offset Double Crankset for Moonlander 170mm 22/36t with Bottom Bracket
The Mr. Whirly Offset Double (MWOD) ditches the large chainring and moves the granny and middle rings to the outer two positions, increasing tire clearance at the chain without increasing Q factor or sacrificing the low gears.

  • This is a complete crankset, assembled; comes with spindle, bearings, bashguard, and all essential parts for installation
  • MWOD chainrings are available separately for converting existing Mr. Whirly cranksets
  • Pugsley version comes with appropriate bottom bracket spindle for Pugsley frames; Moonlander version includes correct spindle for Moonlander frames
  • For 9-speed drivetrains
  • MWOD cranksets are ideal for the Surly Moonlander or for a Pugsley using 82mm rims; in both of these scenarios it helps to use a purpose-designed offset crank to solve the problem of chain-on-tire rub in the lowest gears; no other drivetrain modifications are necessary
