Hi guys,
I built up a wheel around an old Sachs hub this winter. The cassette had been used before, but still looked good with no obvious changes in tooth shape. Anyhow, since this one is from way before shifting ramps and all that I figured I'd flip the sprockets over to be really certain that it would work well with the new chain I was putting on.
Well, it isn't. In the stand it runs as smooth as you'd ever wish for, but when I try riding it I get skipping on both smallest AND largest sprocket, and I just can't figure out why.
Teeth definitely appear symmetrical, the flipped-over side hasn't been run before, there are no stiff links in the chain, I'm not cross-chaining, so what's wrong with it?
Could a faulty chain length affect BOTH smallest and largets cog performance while leaving the middle unaffected?
Can worn tension and jockey pulleys have anything to do with it?
