Changing Campy double to triple.................?(5 posts)

Changing Campy double to triple.................?davet
May 17, 2002 6:45 PM
You guys have helped me out before, so here's another one. My wife is buying a bike with outfitted with Campy Record 8-speed double. She REALLY needs a triple. I know ZERO about Campy. (I have a feeling that I'm going to learn real fast) So my question is; what will it take to change her bike from a double to a triple? And with Campy 8-speed, can I mix the various qualites like Chorus and Daytona to achive what she needs? Thanks, Dave

Yes, you can change from a double to a triple, you just need to buy some parts. They would be the crankset, bottom bracket, front derailleur, rear derailleur, chain and cassette--depending on if you wanted a easier gearing that is. Your shifters will work on a triple already, they were set up with enough adjustment. You may have trouble finding an 8spd rear or front derailleur. I do know that a 9spd will work just fine. As for mixing qualities of Chorus and Daytona, They only make on triple group, called Racing Triple and it is basically Daytona level stuff. It works great. Just make sure you have a skilled mechanic work on it if you aren't. Other than that, Ride happy!

Your first mistake was buying a long-outdated 8 speed group. You'll have to buy so many parts, that it would be better to just get a new Centaur triple 9 speed groupo and start over.

The 8-speed rear hub won't accept a 9 speed cassette and it's not cost effective to change the cassette body. Better to get a Centaur hub and rebuild the wheel.

If you can bail out of this "deal" then run as fast as you away from it!

A C10 double with a 13X29 cassette will handle just about any hill.

you need a triple crank and matching BB.Triple front derailer.use your double rear derailer,but due to lack of wrap capacity you will likely only be able to to use the 4 or 5 largest cogs when in the small ring,no big deal as the granny is a bailout.Pretty sure your front will shift a triple. different parts groups mix ok,but be aware that in 2001, campy changed shifter pull/derailer throw ratios,so the new shifters and rear derailers are not compatible with the old.Being 8 speed makes it a little tougher,but not so bad as some would imply.www.branfordbike.com and the QBP catalogue have alot of info on campy parts compatibility.
