|My 2001 10sp Chorus groupo (rear derailer) is shifting very poorly on both the up and down shifts..ie misshifting and ghost shifting. I have lubed and adjusted the cables and lubed the derailer. The mechanic at the bike shop said it sounded like my shifter needs to be rebuild, which involves replacing these lil springs which are inside the shifter. He said its kind of a yearly maintance thing you do on Campy stuff. The cost is around $70 which I dont mind paying.. But I do enjoy wrenching on my own rig and if this is a yearly maintaince thing I like to learn to do it myself. The guy at the bike store did not reccomend me do it because there are lots of lil part and its kinda hard. |
What do you guys think. Anyone do this procedure? How hard is it. Whats the process?

|Not hard at all. I just re-built a chorus and a daytona.
- Go to brandford bike to order the parts. Tim will tell you what you need. ($70 seems very high)
- download the schematic from the campy web site service manual for your model year.
- dis-assemble on a clean flat bench and line up all the parts so that it will be easier to re-install in the correct order after cleaning, greasing, & replacing the worn stuff.
- the only thing that approaches difficut is the winding of the spring when you put the shifter back together. I used a small flat bladed screw driver and twisted the spring into place.
Also, unless you ride 10,000 miles a year these things should not need re-built every year. I don't know what the service life is but I'd ride them again until they get sloppy once more.

|Thanks for the info. I'm gona try it myself :-) Oh and I really like that campyonly.com website. I was able to find not only rebuild instruction on line but also a part list.

|It is sort of a pain, but if you like wrenching you will enjoy it. I did it and I'd do it again.
I have to question the yearly maintanance regimen though.
