Mr Whirly Crank Set Pugsley
Mr Whirly Crank Set for the Pugsley
Here's how it works. Mr. Whirly spiders are available in 3 common bolt circle diameters (94mm, 104mm, & 110mm) and are interchangeable, as they all connect via the 58mm BCD granny ring holes of the drive side arm. The spindles are CroMoly and are available in two lengths. One is for 68 and 73mm BB shells and the other is for 100mm shells, such as on the Pugsley. The arms and spiders are forged from 7075-T6 aluminum. The whole thing spins on outboard-style bearings. You can get Mr. Whirly as an armset or as a complete crank.
Forged 7075 Alloy,
Inc 100mm BB Axle, BB cups and 94BCD Spider.
