Campagnolo Zondas Cassette installation (shimano freehub)

irishbuzz

Hi All,

These specific wheels seem to be quite topical at the moment so I thought posting this may help other as well as myself.

I'm currently installing a 10 speed cassette on the wheel. In the packaging Compagnolo have included an 'adaptor spacer'. According to the instructions this needs to be put the freehub before the rest of the cassette if you are planning on using a Shimano 9s/10s cassette rather than 11 speed.

However I notice that the first piece of the cassette that is to be installed is also another spacer which Shimano recommends "If using a special 10-speed freewheel a spacer is not required".

I'm a little confused by this. My question is are these 2 spacers actually the same thing? Do I need to use both or just one or the other?

Just one spacer required. I didn't get a spacer with my Zondas so had to buy one. SOME (older?) cassettes appear to have the spacer built on to the innermost sprocket unit, but you possibly dont have this type. In any case, the 10s Shimano freehub will not accommodate two spacers and still tighten up with the locknut.......Note too that the cassette needs 40nM of torque.

Thanks for the reply

Are you sure about this and if so which one should be used?

Comparing the two 'spacers' they differ quite a lot.

On the LEFT is the Compagnolo adaptor and RIGHT is the primary spacer that was included with the cassette.

The Campy is much deeper and has some outward facing indents as well as inner slots (including a large slot) in it





Here you can see better the indents and slots within the campy adaptor. The inscription reads "USE ONLY 9s / 10s"



Here are the instructions that were included for the campy adaptor.

hmmm....that does not look familiar compared to what I faced last year. I'd guess that profiled Campag-supplied ring is the same depth as the 'standard' 1mm spacer inside in the recess, and therefore it mates up to the inside edge of the innermost sprocket while still only spacing it 1mm out from the freehub.

TBH, I think you need to verify with where you purchased, or perhaps someone will be along here shortly to put you right.....

Note too that the cassette needs 40nM of torque.

If not using a torque wrench, that's a pretty decent squeeze?

I'd use the Campag spacer, since it's the one made specifically for that hub.

I'd agree. Maybe I'm wrong but I don't think it would be crucial either way as long as the cassette has no lateral movement when the locknut is tightened?

Yes I think I'm leaning towards the idea of just using the Compag spacer and leaving off the extra Shimano spacer. The indents on the Compag surely indicate that it doesn't expect a spacer to come next so will go with that tonight and let folks know how I get on.

I don't have a torque wrench so I'm just going to go with a pretty decent squeeze alright.

You should fit both, the Campag' one first and then the Shimano one, the cut outs are to allow for cassettes that either have small bolt heads or rivets protruding on the inside that are holding the sprockets together, sometimes found on 8 and 9 speed cassettes.

Haha, just when I was finishing up. Oh well gives me a chance to have a go with a chain whip

Cassette is on now and I've put on the tires and tubes. Just have to wait til Monday now when I'll be reunited with my bike and I'll put it all together.

Thanks for all the help guys.

Hi

Is that for definite that the 1mm spacer that comes with the Shimano cassette goes on after the one supplied with the wheel from Campagnolo, or is it just an opinion.

Well I've been running them that way since and it's been all good Dubflier

I have these same wheels, but installed only campy spacer for 10s cassette. No issues. Remarkable wheels, at least for me. These use loose bearings, hence some looking after is required. Worth checking the rear wheel for wobble (while mounted) and tighten if required after about 500km.

Enjoy!

Hi irishbuzz

I assume that is with the 1mm shimano spacer washer fitted as well as the campy on too.

Exactly yes
