Hello, all. I'm not a wheelbuilder, so help me out here -- I recently purchased a used set of shimano-freehub Ligero Model 1s with a powertap sl hub. I also bought a campy freehub replacement from cycleops. The freehub instructions say to toss the aluminum washer/spacer when switching to campy, and indicate that one of the two steel washers goes in a slightly different location on the campy setup than when running a shim/sram setup. I believe I did the transplant correctly, but the wheel is now significantly left of center when looking at it dead-on from behind when in the dropouts, and further the rear derr. shifts into the spokes when on the big rear cog. Sounds like dish problem, right? But my concern is maybe I screwed up on the assembly. Or both perhaps. So does anyone know off hand if you normally are required to redish a wheel when switching from a shim to campy freehub on a powertap sl setup? Thanks much.
