Campy 9spd crank and ft der shifting problems w 10 spd rear der

[Alan]

I am trying to use a 2001 era (about) racing triple crank which is 9
spd on a 10 spd setup in the back and a 9 spd triple f der. I am
having problems shifting the ft der. Campy says on their web site
that the spacing is different between the 9 spd crank and 10. Can I
get different chainring bolts to fix the spacing problem? If so let
me know what I need.

Do you think the 9 spd ft der is causing problems with this setup?
Per campy again they say this will not work.

It would be easier to get a f der than a new crank.

Thanks so much. I appreciate the help.

What Campy tells you is beside the point for your 9 spd cranks. If you
had a 10 spd crank, you could buy shims to pad out the space between
the chainwheels
for use with 9 spd chain, because yes, there is a tiny reduction in
the distance between the crankarms for 10 speeds.

If you have a problem, it may be narrower spacing between the cage
halves of the rear der.. A pair of very, very thin washers can take
care of that.

Sorry I meant to make it clear that this is a 10 spd setup w a KMC 10
spd chain and the back shifts fine. Problems are on the front der and/
or crank.

Perhaps you could describe the shifting "problems" with the front
derailleur and crankset?

And are all the components involved in serviceable condition?

I've been using my C-Record crank (officially 8speed I suppose) with
8, 9 & 10speed drivetrains without any problems. I don't think the
crank is the problem - I'd check to make sure the FD is setup
correctly.

The crank is not the problem. Unless your left lever is QS it should
function well. With a QS lever it may require extreme effort or a new
front changer.
What sort of 'problems'??
