I'm posting this here because I think there's more familiarity with the "older" Campy brifters here than other subforums.

My '97 Bianchi Trofeo came stock with eight speed Mirage brifters. The right brifter has developed an issue where it shifts the RD fine from the smallest to the second-largest cog and back, but needs to be double-tapped to make it onto the largest cog. It also needs to be double-tapped to get centered on the second-largest cog from the largest cog. The cassette is a 13-26 Miche.

My LBS guy has taken apart and reassembled Shimano brifters, but has never had the occasion to take down a Campy one. He has in his memory that it should just require a G spring and a couple of other parts, but he's not sure, and is honest enough to admit it. He's going to check around, and asked me to do so as well. He's got a 2000 QBP catalog with the parts schematic, so we can check to make sure we have the nomenclature correct.

Is his analysis and proposed fix correct? If so, are the parts available? Alternately, is the brifter FUBAR?

Thanks!

There is a guy on the paceline forum. His name is peter vecchio, and he goes by the name oldpotatoe. I think he is supposed to be expert in rebuilding ergos.

Aren't those '97 Trofeo's great! I have since sold mine - only bike I ever bought new. The 8 spd Mirage brifters worked flawlessly for me for years except for a small vibration. Have you tried any kind of degreaser/lube to make sure there's just not something gummed up in there.

The rebuild requires 2 new G-springs (right-hand specific) and about 30 minutes if you've done it before. Or about 2 hours and a fair amount of stress for the first time. The older levers, which you have, are a lot easier to put back together than the later levers that have the coiled helper spring.

You may want to install fresh hoods while you're at it.

These levers, as far as I can tell, have no limits on their lifespan. I have a set of Veloce levers about the same age as yours. 4th rebuild and good as new.

BTW: Campy levers are far easier to repair than Shimano levers.

Chuck,

The symptoms you describe are similar to those of worn/sloppy wheels and worn/loose derailleur pivots.
