Setting up a campy triple FD

Hello people,

I need some help in setting up/adjusting a campy triple FD. The bike has:

1. a Centaur crankset with 50x40x30 and a QS Race Triple 10 Speed FD
2. the shifter is QS Veloce.

I have no issues with shifting between the outer and middle rings, up or down. However, I do have problems shifting from middle to inner, but not the other way. I have read up on the campy site as well general bike mechanic books and to the best of my ability ensured that barrel adjustment as well the limit screws are set. On the stand the shifting (middle to inner) is fine, there is a slight hesitation, say just over one pedal revolution. The problem really manifests itself when I on a hill. I have tried to shift without loading the pedals too much but that has no effect. I can 'force' the shift if I change the rear gears so that I am either in the largest or second largest ring of the cog-set (13-29). Appreciate any advice; is it just technique on my part or some other adjustment?

Thanks.

If the derailleur low limit was set correctly, with the chain on the inner chainring and the largest cassette cog, then it sounds as if you have too much tension on the cable (front derailleur).
It's best to set the low limit screw with the cable detached. Then with the shift tab all the way down and all of the cable out of the shifter, attach the cable with no slack and no tension. Add tension only if necessary to shift to the largest chainring.

I have the same setup except with a 53-42-30, and no problems at all.
The only thing I can think of is that depending on the diameter of your seat tube, there are different dimension FD's and BB's recommended. Have you checked that?

Thank you

Based on the advice, did some adjustments on the FD and voila the commute this morning was very smooth:

1. I checked the cable tension and with the chain on the inner ring and large rear cog, the cable was quite tight. I loosened it and basically took up the slack.
2. Also adjusted the H and L limits - initially I thought they were okay, but, I think a little more tweaking was required.

Anyhow with the cable tension set appropriately and the limits also adjusted, the shifting is very smooth.

Thanks again.
