10 speed Campagnolo cassette issues

[Rhythm Thief]

I've fitted a ten speed Miche cassette to a Campagnolo freehub previously used with 9 speed. Everything I read on the web tells me it should fit, but when the lock ring is torqued down there's maybe 1mm of play in the cog stack. Is a spacer required?

 

[fossyant]

Yes is the answer. There is no other way it will do up without a spacer. Ebay/Amazon is full of kits with various thickness spacers for not much money if you don't have spares.

Yeah, you need a 1mm spacer behind the cassette. A 9-speed freehub body is just a hair shorter than a 10-speed one. That spacer will take up the slack and lock everything down tight.

Strange things , I'm using all brands 9 and 10 speed cassettes on Campagnolo freehubs for appr. 15 years now and NEVER needed spacers...

This is the opposite of what the TS expierienced....

There can be differences between hub manufacturers - it's pretty standard on Shimano/SRAM fit, but if a cassette is too short, you'll need a spacer.

Don't deny that, but I as hardcore Campagnolo user am a bit surprised because it does n't match my expierience...

Your experience is unusual. Most wheels need that spacer because the Campagnolo freehub body is longer. Your specific wheels must be a rare exception where the fit is perfect without it.

 

[Keezx]

Sorry, but I 'm assuming that you NEVER ever fitted a Campagnolo 9/10/11 speed cassette on a standard 9/10/11Campagnolo freehub, because needing spacers doesn'n make any sense...
Shimano, yes.

 

[fossyant]

It's a Miche cassette...

 

[fossyant]

And is it a Campag genuine hub. I get differences on Shimano compatible hubs, not any cassettes of any make. Use spacers to sort that.

 

[Keezx]

As you should, but ithat's irrelevant for the TS.
Miche cassettes ARE different from Campagnolo's but definately not a few mm narrower...still a mystery.

In the end, it didn't need a spacer. I tried a different lock ring with a deeper thread and everything worked fine.

Beat me to it and glad you got sorted but I was going to add..I once removed and refitted my Veloce cassette (done it many other times) but on this occasion, some ot perhaps all the sprockets were slack despite the lockring being tight.
I shortly realised the last sprocket wasn't sitting on the splines as I tightened up the locking, so clamping it AGAINST the freehub instead on ON it. Undid it all, refitted, fine.

Perhaps what happened to yours without you realising it ?

Yeah, could well be. I'd previously had the cassette fitted and had done a reasonably long ride on it, and I'm pretty sure I'd have noticed any loose sprockets!

 

[Keezx]

Well it seems my expierience, in not needing spacers, was spot-on....
