I just had my first tune up on my bike. It has Record 9 sp. and it is a 52cm Serotta. The chain was
worn, so I got a new 9 sp Campy chain and a new 9 sp Ti Cassette. (12x23). It was having problems in
the top 4 gears, so I also had the shifter rebuilt. (I did not get new gears in the shifter -
springs and one other part). It is still having problems in the top 3 or 4 cogs. Problems like going
up (in number of teeth), it clicks and makes all kinds of noise. It is like it wants to go 1 1/2
steps per click of the lever. If I tap the thumb shifter lever gently, the noise goes away. I took
it back to the shop, and am now trying a Dura-Ace chain. Still has the same problem. The gruppo was
purchased used with around 1k miles on it, and I have since put 2500 or 3000 miles on it. I put 2000
since last March.
Anyone have such an odd problem? Anyone have any tips? Going down (in number of teeth) is smooth and
never misses. Going up or down multiple clicks also works excellently, never misses. What about the
Derailleur itself? are there parts I should replace or look into?
