Changing Mavic freehub bodies

marge602

Hi folks

I've been a BikeRadar user for about six months, and felt i should join the forum, since i'm on a few forums for other interests i have.

My road bike has a set of Aksiums on, and i'm considering upgrading them to some Kysriums. The roadie has Campagnolo, and my winter bike has Shimano. If i buy the new wheels with a Shimano freehub, can i swap it over and use the Aksiums on my winter bike?

Also, my road bike is 9 speed Campag(it's a good few years old) and my winter bike 8 speed Shimano(it was cheap!) All the new wheels i've been looking at are 10/11speed. How does this affect my plans?

Thanks

Marge

i.e.
- currently your road bike has Aksiums, with 9sp Campag
- you want to put Ksyriums on it
- you want to put the Aksiums on your Winter bike, which has 8sp Shimano
- so you're considering buying Shimano-hub Ksyriums, taking the Shimano-fit freehub from them and putting it onto the Aksiums, putting the Campag-fit freehub off the Aksiums onto the Ksyriums
- that it ?

I don't see a problem.
Both Aksiums and Ksyriums use the Mavic FTSL hub system, where there's a CD10 freehub for Campag and a M10 for Shimano, which are interchangeable.

I wouldn't worry about 9sp Campag vs 10/11sp : your existing freehub on the Aksiums works fine with your 9sp Campag, so will work just the same on the Ksyriums.
You need to get the Ksyriums with the Shimano-fit M10 freehub, which will work with 8/9/10sp Shimano

What you do need though, is a Mavic spacer which should come with the M10 wheels.
The M10 freehub is not Shimano per-se, it's Mavic. It has Shimano splines so a Shimano or SRAM cassette goes on it, but Mavic also make a Shimano-splined but Campag-spaced cassette which will fit on it : this is wider than a Shimano cassette, so to fit Shimano onto it you need this spacer on the hub before the cassette is fitted : without it, you can't tighten the locknut enough and the cassette wobbles loosely on the hub.
As I say, if buying these wheels new it should come with it and this is the only spacer you would need if using Shimano 8sp.

Yes you can, I did exactly what you want to do, without any problems, (although the bike shop did it for a 10er and half an hour)

Spot on! It's not that i'm blind to other makes of wheels, but i could kill two birds with one stone, make both my bikes faster and lighter and get a few quid back from selling the current winter wheels on. Thanks for the sound advice.
