Ultegra triple problem(5 posts)

Ultegra triple problemThierry

I just bought a 2002 model of the Trek 2300. It comes with Ultegra triple and that's one of the reasons why I bought this one. However the front derailleur doesn't work well: it jumps from the largest to the smallest ring without stopping on the middle ring. So far my LBS has not been competent enough to fix it. They say it is due to cable tension which they adjusted but that didn't fix anything. What shall I check?

Ihave an Ultegra triple and have never had that problem. My suggestion: find a competent LBS and
a competent mechanic. In the meantime, maybe grz or someone else who knows what he's talking
about can comment. Good luck.

that comes with the Ultegra front derailleur has a troubleshooting list with specific suggestions for specific problems.
I have it at home and I'll try and post the correct info. to you.
Sounds like your LBS tech's are pretty simple minded! Did they sell you the bike?

STI triples can be a bear to set up.

My experience has been that the problem is usually how the front derailleur is mounted on the seat tube. If your LBS has had difficulty in getting the bike to shift properly, chances are everything has been moved all over.

My advice: Go back to the default setting. Disconnect the cable completely. Make sure the outer cage is parallel to the big chain ring and just misses the big chain ring by a few millimeters when you shift. Without the cable attached, the chain should just miss the inner cage when the rear is in the big cog.

One last thing. If they have been jacking around with it that much, the shift cable is probably buggered beyond recognition. Get them to put on a new one.
