Adjustment for STI Front Triple?(5 posts)

Adjustment for STI Front Triple?BardamuG
Apr 9, 2002 3:37 PM
Anyone know if there is any other way to adjust a triple front derailleur other than cable length? I have Shimano 105, and the problem that I'm having is that when I shift from the small ring to the middle, I have to shift past the catch on the lever to get the chain onto the ring. Then I have to release the shift lever one click so that the chain doesn't rub on the derailleur cage. No matter what kind of adjustment I make to the cable length, I can't avoid this. So I am wondering if there is any way to adjust the throw on the lever? And on a related question: what is that little roller attached to the cable housing of the shifters and how does it work?

Thanks for your help.

The shifting problem you have described seems to be common to all triples, at least that I am aware of, and it's the very reason I don't like triples. They take too long to shift and then there's all that trimming nonsense. Sorry, I wish I could help you, I've spent a lot of time trying to make my wife's triple shift better, and it's never good enough. I'll eat worms before I buy another triple.

Yea the Ultegra triple front der, does the same.
Triple is nice, but the shifting is sloppy no matter what you do to it.
Maybe the DuraAce triple is nicer ??

If you're going to have a triple I think the Dura-Ace with the 39 middle ring is probably the best, but I think they should offer a smaller big ring, most of us don't need a 53, a 51 would make a nice option.

After posting this message I've given it some more thought and think that perhaps drivetrain wear might have something to do with the problem. When I bought the bike, it shifted beautifully. Now, I have about 7,000 miles on the drive train, which may put enough slop in the chain so that it won't mount the middle ring. Still a problem, but if I replace that stuff, hopefully it will improve.
