    a rear cluster FYI

    For weeks now I have had a skip in two gears on my five speed rear cluster (vintage ride) when I was on the middle cog or the smallest cog it would skip or jump when I applied pressure to the peddles.

    I examined the cogs closely and could find not one thing wrong, nothing worn or broken and I assumed it was a bent RD but a friend of mine had a NOS rear cluster so I put it on yesterday and rode 50 miles today and it is like a new bike..easy to shift and no skip at all.
    I can"t explain it but I guess it can happen.

    I'll guess the skipping started right after you installed a new chain.

    Used cogs can skip with a new chain even if they have no visable wear. By the time the cogs are noticably hooked or deformed they are way beyond hopeless.

    BTW, some older 5-speed freewheels had cogs that could be flipped over on the ratcheting body and that presented a new, unworn face to a new chian. You could get double the use from them.

    When replacing a freewheel/cassette, you should also replace the chain. An old chain will cause premature wear to the new cluster. If it works at all that is.
    How do you keep an idiot in suspense?
