I have two bikes w. Campy shifters. I use Shimano-
compatible rear wheels almost all the time. I am
considering upgrading to compact cranks, but only if I can
use 10-speed cassettes. Can I put 10-speed Shimano
cassettes on my Shimano-compatible rear wheels and shift
them well using my Campy shifters?
What I have: 1999 Athena 9-speed shifters (late '99, fully
compatible with everything since). Will need to be upgraded.
2004 Centaur 10-speed shifters
FWIW, I am happy to report that running 9-speed Shimano
cassettes with the above always worked well. (Of course,
running Campy worked too.)
Thanks.
Kirby.
Campagnolo 9-speed center-to-center 4.55 mm, cog thickness 1.75 mm, and spacer thickness 2.8 mm
Shimano 9-speed center to center 4.34 mm, cog thickness 1.78 mm, and spacer thickness 2.56 mm
Campagnolo 10-speed 4.12 mm, 1.75 mm, 2.42 mm
Shimano 10-speed 3.95 mm, 1.6 mm, 2.35 mm
I think that the same "sloppiness" tolerance will be there with the requirement for reduction of ~0.2 mm rear derailer movement for each increment on Dura Ace 10 cassette. I always wondered how it worked with the indexing differences, stop positions, and cumulative errors. I am to Anal Retentive to try it at this time, but I certainly have seen the 9 speed swap working on many bicycles.
I would start the experiment with a DURA ACE 10 speed chain, just because it is slightly narrower on the outside.... however lateral chain width and lateral chain flexibility are both considerations.
