Default Re: Cranbrook, Chain shake/flap/slap

i've done a few crane brooks and i know what you mean by, the sproket is up against the spokes, on the crane brook to get the sprocket lined up with the engine sprocket you leave out the outter rubber and just use the inside piece, that puts the sprocket up against the spokes. but now theres not enough clearance for the 2.125 tire and the chain will rub and jump all around, a smaller 1.75 tire works much better when only running the one rag joint. you may also need to bend the coaster brake arm to clear the sprocket bolt heads.
