S Cassette on C drivetrain

[velozoom]

I've heard vague rumours that it is possible to run a Shimano 10 Cassette on a Campy 10 drivetrain with little to no problem. I have all S components/wheels now and want to switch but I can't afford all new wheels or +$100/ea conversion cassettes.

I am aware of the JTek shiftmate but its ugliness is making me hope there is a simpler solution.

So my questions-

A) will a S cassette work with C shifters/rear der?

B) HOW well will it work? i.e.- will it skip annoyingly or not shift at certain times?

C) if it won't work out of the box, are there other tricks or tweaks other than the shiftmate?

Thanks

I have this problem too. 5 Shimano bikes and I just got a Campy CF Cervelo Soloist Team from ebay. I'll be using an American Classic conversion cassette for Shimano to Campy and it only costs $70 from Lickbike?

I'll also be experimenting riding my campy on the shimano and the shimano on my campy. But that'll happen after I get my Cervelo on Monday.

It won't work out of the box because the Shimano cogs are spaced closer together AND you MUST use the narrower Shimano 10-speed-compatible chain with the Shimano 10-speed cassette (do you have the chain, too?).

Based on MY (singular?) observation that it appears that you can substitute a Shimano 10-speed rear derailleur (a very brief workstand test, only) for a Campagnolo rear derailleur AND (follow me, now) because the indexing of the 9-speed Shimano can be simulated by using Shimano's alternate anchor position (at 9 o'clock), THEN if you were to anchor the rear derailleur cable at 3 o'clock (aka, the hubbub.com alternate anchor position), then it should (no promises) result in a 10-speed Campagnolo shifter approximating the indexing for a Shimano 10-speed cassette.

That is, you should be able to make the Campagnolo ERGO 10-speed shifter index to Shimano's 10-speed cassette by using the hubbub.com alternate anchor position.

Some day, I'll get around to picking up a 10-speed Shimano cassette to verify this OR you can give it a try ...

You can just put a Wheels Manufacturing Shimano-to-Campagonlo 10-speed cassette on your rear wheel UNLESS it has a 7800 hub AND use the standard rear derailleur anchoring. As noted, American Classic is the name of the other brand of Shimano-to-Campagnolo cassette.

My Wheels Manufacturing 10-speed cassette began life as an Ultegra cassette ... I think there is/was a Dura Ace version. The rear of the Shimano spider is milled out (about 3-or-4 mm) to allow the cassette to sit closer the centerline ... the loose spacers are thinner, and the lockring is milled.

So, you can theoretically MAY be able to just get a set of 10-speed Campagnolo shifters ... and fiddle with the hubbub.com anchoring ... OR, get the shifters and a Wheels Manufacturing or American Classic Shimano-to-Campagnolo cassette if you want to use a 9-speed chain (a SRAM 89R chain was a common substitute for Campagnolo's 10-speed chain).

Hope that made sense!

Thanks for the replies but, sorry alfeng , I'm still a bit confused. The hubbub.com articles appears to describe how to run a 9-spd cassette on a 10spd drivetrain. My goal would be to use a 10spd Campy drivetrain (shifters, front der, and rear der) with a Shimano 10 spd cassette.......

The KEY thing for you to be aware of is that there is a THIRD place where you can anchor the rear derailleur cable (i.e., at 3 o'clock).

The hubbub.com anchor position with the Campagnolo ERGO shifters + a 10-speed Shimano rear derailleur -- OR, by my reckoning, a Campagnolo rear derailleur -- should (but, may not!) provide you with indexing suitable for a Shimano 10-speed cassette.

That is, the hubbub.com anchoring position results in the rear derailleur moving a SMALLER amount ... and, by my reckoning, it is the amount to allow the 10-speed Shimano (or, Campagnolo) rear derailleur move the appropriate amount when mated to a 10-speed ERGO shifter to index to a Shimano 10-speed cassette IF THAT IS WHAT YOU ARE "STUCK" USING for the time being -- when the 10-speed Shimano cassette + ~3 chains wear out, you can get an American Classic or Wheels Manufacturing cassette for your Shimano wheel IF your wheel has a non-7800 hyper-splined (to coin a term!) Shimano-compatible freehub.

Utilizing the hubbub.com anchoring position to force a mating between a Campagnolo 10-speed shifter + 10-speed Shimano cassette is an on-paper & workstand-only supposition & testing & extrapolation that I have done with everything BUT a 10-speed Shimano cassette, and it may not be viable on the road with your specfic components -- or, as they say, your results may vary -- but, I don't see why it wouldn't work.

BTW. The anchor "washer" on the (i.e., MY) Campy rear derailleur is less "happy" about being rotated into the hubbub.com position; but, since you had indicated, originally, that you had the Shimano drivetrain, there is NO need to buy the Campy derailleurs.

You know, Shimano STI shifters still have what I refer to as a Lance-premium which means that you will get 2x-to-3x more for a USED set of STI shifters as the replacement cost of a NEW pair of Ergo shifters (unless you opt for Chorus or Record, that is).

Hope that makes sense, now ...

I agree with JTE83's reco of a conversion cassette if you don't want the ugliness of a jtek. I currently run (on one of my bikes) Record 10s drivetrain using Easton Vista SLs w/ shimano splines (they dont make camply splines) and use an American Classic conversion sprocket. Before the eastons I was using a Record 10s rear cassette and to my surprise the AC somehow shifts smoother than the stock Campy. I think maybe its the way the AC sprockets are coated or finished and they never seem to get dirty.
