I want to do this, can someone tell me what size Whirly I need for the KM BB shell?
Go buy a Pizza
you'll need the 68/73mm spindle
Cool Thanks !
Then I suppose I get the Single Speed version and add my 31T Ring? I cant seem to find an image of the inside of the Single Speed Drive side !?!?
you'll need to add longer chainring bolts as well as the 31t ring, then you'll have an awesome dingle setup.
