Campag cassette

[Jonathan Schneider]

I've just experienced trying to replace one of these new fangled
cassettes and failed.

My two and a bit year old Dawes Giro 400 has a well worn Campag Xenon
set so I ordered what I thought would be a compatible 12/23 9spd
Veloce Exadrive cassette, there being a choice of that or Mirage or
£ lots more. Even a sales enquiry to the retailer gave me confidence
that it would fit. Or should I have specified a lot more than just
Xenon ?

But the splines on the bike have on spline with a central groove in a
ridge if that description makes any sense.

The new cassette however is obviously meant to go where there is one
asymetrical spline. Is that the Exadrive in its name ?

What do I need to do apart from throw a tantrum ?

Cheers,

Jon

Start filing?

I'm not familiar with Campy cassettes but a little googling leads me
to think that Campy cassetes comes in three flavours; really old equal
splined, EXA and Ultra.

It's a shame you didn't take the old cassette off first and look at
the spline pattern and then make the call. But how were you to know
Campy had changed sometime in the recent past? I'd say you are not
alone in this, the majority of sites don't seem to emphasise the
incomatibility of EXA and Ultra.

Mr. Retailer should take back the unused cassete and send you a new
one that does fit. They ought to know that there are different
flavoured splines and should have asked you if you were certain what
flavour you wanted when you made the call since you were asking if it
would fit.

Not to me at the moment.

I don't understand. All Campag 9-speed cassettes are interchangeable.

What make is the hub? I'm wondering if you have a non Campag hub with a non
Campag cassette.

EXA Drive and Ultra Drive is to do with the tooth profile, nothing to do
with the splines at all. They both fit on the same hubs.

Can you take a picture of one of the sprockets? Feel free to email it to me
if you can't put it on the web. Pics of the hub (without cassette) would be
good as well.

*All* Campag 9/10-speed freehubs have one asymmetrical (L-shaped) spline,
and all Campag 9 and 10-speed cassettes have the corresponding asymmetrical
spline tab.

See
http://www.campagnolo.com/pics/MIR_Hub_rear.jpg

Some other brands of cassettes, and Campag 8-speed cassettes and hubs, don't
have the asymmetrical spline.

I once had a Campag sprocket that didn't quite fit because it wasn't quite
made right -- needed a bit of filing -- but I guess you've got a more
serious incompatibility than that.

That's 8-speed.

EXA and UltraDrive is to do with the teeth not the splines. See

Actually there have been two variations on the Campag 9/10-speed freehub
design, but they both take all Campag 9/10-speed cassettes.

New cassette does but as the picture doesn't show all that well does
not correspond to my hub and old cassette (pictured half-cleaned).

Apart from the L-shaped tooth thing the new cassette seems to be meant
for a hub of a slightly smaller diameter.

Think I'll ask the shop and/or Dawes what I have.

Nah. Their one's all shiny.

Those sprocket and hub splines look too shallow to be Campag 9-speed, to me.

Are the sprockets marked "Campagnolo"?

I'm suspecting that isn't a Camopag hub.

Applied a little elbow grease to the hub (why on earth didn't I much
earlier) to reveal Miche Team Box C0504. Their website doesn't say
much but does have contact details for a UK rep who I have emailed.

It looks an awful lot like the one on my bike. Which I know is Shimano,
but didn't know until today is therefore incompatible. So, can I be the
second member of the "shiny new campag cassette and nowhere to fit it"
club? :-(

Mind you, after the nice man at Bikefix this afternoon pointed out how
much play there was in it (the hub) anyway, I'm thinking "excuse to buy
new wheel"

But Shimano hubs have twelve splines. Mine has eight or nine including
the extra one. I think I need to take another happy pill at this point.

As Miche cassettes aren't brought into the country (only the track stuff is) the only place to get a replacement cassette was from Dawes where the warranty guy had some in his big pot of spares.

Marten,

Thank you thank you. That's the first bit of information that makes
sense !

If this is correct maybe I should exercise some consumer rights and
generally stir as this state of affairs is clearly unreasonable.

I guess a good solution (though I don't have time nor should I and
have only done the course) would be to get a Campag hub and rebuild
the wheel.
