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.
