2012 Surly MWOD (Mr. Whirly Offset Double) Cranks
New from Surly Bikes for 2012 are cranks called MWOD (Mr. Whirly Offset Double), which is designed to tackle the dilemma of bikes with massively oversized tires having chains rubbing on the tires. A new spindle, which is longer than the existing Pugsley spec spindle, will also be used.
While the MWOD utilizes the Mr. Whirly arms on hand, the middle ring shifts to its place after the big ring is dropped. In essence, the granny ring mounts directly up to the spider mounting holes. The middle ring connects to the granny ring afterwards.
For riders who have bikes with very big tires, the 2012 Surly MWOD (Mr. Whirly Offset Double) Cranks are a great help. Aside from being rearranged, the rings are exclusively designed by Surly. Tooth options include 20/32 and 22/36. It will be available in black.
