New bike, 105 components, derailer rubs and shift s poorlyJRF
Sep 3, 2002 6:15 PM
I just purchased a Kline Quantum, sweet ride but there were some gears that wouldn't work (mostly hi/low adjustments) and the front derailure rubbed on some gears. This is a triple crank set up. I tried to adjust but had no luck fixing the problem. I have had mountian bikes for years and always did my own wrenching on it. However I have failed misreably at adjusting this bike. Is this normal for triples? Any insight would be great. I think I am taking it back to the LBS for them to deal with it. Love to here your thoughts.

It should be fine in all except for the 2 or 3 most extreme chain angles. You should stay away from those, as always. If it is rubbing more often than that, it does need adjustment and should be performing better.

Too add to the above replies: most road bikes have shorter chainstays than most MTB's, this causes more drastic chain angles and makes road triples a bit more finicky to adjust. If you just bought the bike, take it back to the shop and have them tinker with it.

Go back to the default position before you start adjusting. Disconnect the shift cable. Make sure the front derailleur is properly mounted on the seat tube. Make sure that the low gear limit screw is right. Then make sure that your shifter is in the lowest position, reconnect the shift cable, and concentrate on the cable tension.

When you get it right, you will have one shift position for the granny, TWO for the middle ring, and one for the big ring.

Good luck.
