Converting campy cassette carrier to shimano?(9 posts)

Is it possible to change the cassette carrier on a set of campy electrons to shimano? If so, how is it done and what parts are needed?

On some hubs you can switch the freehub body. I know you can with Zipps and Ksyriums, and probably the Electrons. I'd email someone at Branford Bike or Campy Only, if you don't get a definitive response here.

Yes, you can buy shimano splined body. nmSpunout

why not just run a conversion cassette? nmrussw19

First, they are heavier. The American Classic one I tried weighed about 220 grams, and was a modified Ultegra cassette. I didn't buy 1200 gram wheels to put a 220 gram cassette on.

Fit problems. The big cog gets dangerously close to the spokes, or at least gets the RD cage close, and there may not be much bite for the lockring.

The conversion cassettes don't re-space all the cogs, just the front and rear of the connected cogs, not in between, so some shifting is compromised.

It would not fit on my Velomax hub. No way.

It could be cheaper to replace the freehub body. I think it was less than $100 for a Ksyrium, and the conversion cassette is more than that. Of course, you'll still need a cassette.

Conversion cassettes are not available in all the normal cog combinations. You are limited.

Good reply... Thanks Doug!

I did know the cassette was heavier, but I didn't know it wouldn't fit Velomax hubs.

However, I was under the impression we were talking about converting a Campy hub to run a Shimano drivetrain. Wheels Manufacturing makes a cassette that is splined to fit the Campy body, but spaced for Shimano 9 speed. Or even easier, couldn't you just change the spacers?

I think we are making this harder than it has to be.. and I don't think you have to change out the freehub body.

You're a bit confused. Wheels manufacturing does not make a campy splined cassette for shimano 9 speed. They make a shimano splined cassette for campy 9 speed (and 10 speed).

Spacers can't be changed on todays cassettes. The cogs are riveted together (in groups of 2 or 3 cogs) on aluminum carriers that have no removable spacers.

If you want to run a shimano drivetrain on a campy wheel, the smart way is to change the cassette body to a shimano compatible model that campy manufactures.

Unless I am reading the Quality webpage wrong... Wheels Manufacturing Shift Kit 7 is a spacer kit to convert Campy 9 speed cogs to fit Shimano 9 speed spacing. That does go on the premis of individual cogs, but it can be done. It lists the Start Cassette as Campy 9 speed (I interpret that to mean a Campy 9 Freehub body) the Shifter-Derailleur as Shimano 9 (Shimano shifting) and the End Cassette as 9 Speed Shimano Compatible (meaning spaced for shimano shifting) I could be wrong, but I can call Quality on monday for an explaination.

But yes you are right, it needs indiv. cogs, but I like that anyways, as I live in a flat area and don't wear full cassettes, but more likely only 1 or 2 cogs. You can order the kit for $16.00 wholesale, and indiv. Campy cogs are around $7 to $10 each wholesale... the exception is the 11A-1P up front it may cost more, but you only replace the cogs you wear, so long term, it saves money. Also to go with a new body you need that and a cassette. That is gonna be way more. If I am reading the parts catalog right, the Record version of a Shimano HG freehub body is $85 and the Chorus version is $58 (both prices wholesale, not retail) so I have to wonder what the best route really is. Oh yeah, and a Dura-Ace cassette is $50 wholesale, so it gets exspensive...

I am not saying any of you guys are wrong, I am just trying to let you all in on another way to do this that may end up quite a bit cheaper and easier in the long run.

now you're making sense.C-40

Yes you can use a campy 9 loose cog cassette with thinner spacers between all cogs except the smallest, which has the spacer built into the cog. Wheels Manufacturing may machine the smallest cog to reduce the spacing. A spacer is also needed to make up the difference in the total stack length, which is shorter with the shimano spacing.

If the user wants the lightest DuraAce cassette, then changing cassette bodies is the way to go.
