Shimano 9-sp chain ring compatible with 10 speed Campy?

[Steve Karpik]

A rider that I coach owns a Shimano Octalink style SRM crank set. She
is being sponsored by a team that will provide 10-speed Campy equipped
bikes. We're thinking of taking out the Campy bb and replacing it with
a Shimano Octalink bb so she can use her SRM. Will the Campy 10-speed
chain and front derailleur be OK with the 9-speed Shimano chain rings
mounted on the SRM crank?

There's no way that she can afford to buy a new SRM that has the Campy
bolt circle. Any suggestions.

Thanks for all advice.

Yes, w/o probelm and w/o any modification.

The left/front ERGO is such that you can use any front der/crank combo and the
10s chain will mesh just fine with shimano rings.

they mesh fine, being as they're the same pitch & all, and they /do/
work, but the pickups on the 9s don't work as well on the 10s chain as
they do on the 9s chain. the two chains are very different in design -
the 9s having bulges in the outer plates specifically /for/ pickup.

the chain'll work, but it won't shift as cleanly as if she had the
shimano 10s chain ring - different pickup config on the 9s ring
"prefers" 9s chain.

the campy shifter will shift anything.

The side plates of Shimano 10 and Wipperman 10 are flat. In the
limited playing I've done, the flat plates don't pickup as quickly on
the shift assists of any ring.

Using a Campy system and Shimano 9 chain, I can shift up to big rings
with just bevels and no ramps or pins. With the flat sideplate, I
need a more pronounced shift pin and ramp. The rings I've used are
FSA from the Compact crankset, SR/Maes from years ago, Shimano HG, and
2002 Stronglight.

The cheapo IRD 10 chain has worked the best for me among the 10 speed
chains. I have no experience with Campy chain. I always use a
removable link.
