Hi, so here we go. A few years ago I bought a basket case XS2. It literally came in boxes. The seller had said that the front rim had been bent in an accident and he had included a replacement as well as the original disc that was on the bike. Well the original disc is the floating type and the rim he found to replace the bent one has the disc attached. Because the "floater" had a hollow shaft that ran through the right fork leg with the axle running through that, I'm sure a spacer or the shaft itself would need to be used if I could make the 73 work. Has anyone replaced their 72 rim with a later model wheel? It's either make it work, get new fork legs, or find a new wheel and hope there is no play where the rotor fingers meet the hub.
