Surly

Mr. Whirly Spindle for 100mm BB Shells - Moonlander

This part holds the key to success in mating your Surly Moonlader frame with the Surly Mr Whirly crankset. The Moonlader is designed to be used with a crank that has a 28mm lateral offset to accomidate the massive 4.7 inch Big Fat Larry tires to roll through mud, sand and snow.

This spindle along with the MWOD (Mr Whrily Off Set Double) chainring will be required to upgrade your Mr Whrily to be used on the Moonlander.

• Fits 100mm Shell Frames
• Includes necessary spacers
• Will not work on the Pugsley or Mukluk because they are designed around a 17.5mm offset.
• Fits Moonlander and other Fat Bikes using 28mm offset "standard"
• Surly Mr Whrily spline will not work with other cranks.
• Spindle is made of 100% CroMo
