Hi,

How can I tell if a set of Cosmic Experts are compatible
with Campy Chorus 8 speed? Are those wheels appropriate
for a heavy rider(~215 lbs)?

Thanks in advance.

I had a set of these wheels and really loved them. I sold
them to a guy 'cuz I just had to raise money for a set of
Velomax Javelins which didn't end up being near as good as
the Mavic Cosmic Experts. As for the campy compatibility, I
couldn't say. They came out in the era of 8-speed, but
you'd have to know if they have a campy or shimano freehub
I suppose.

As for handling a 215 lb. rider ... as old as those wheels
would be by now ... I don't think I'd try it. Also, those
wheels have a psi restriction. I believe they're only rated
to 110 psi. I didn't realize that until I started running a
set of tires at 125 and developed little cracks in the rim.
I had to replace the rim and settle for running tires at 110
... which was fine for my purposes at the time.

No and IMHO no. Although you could conceivably put on a
Shimano cassette and use the Wheels Manufacturing spacers to
convert it to Campy spacing. As a rider of similar weight, I
had two rim failures with these wheels in under 1000 miles
each (actually, under 500 miles). Mavic squirmed out of
warranty replacement as is their standard strategy.

That's Mavic [censored] to avoid warranty claims. The rims
crack several mm up the sidewall from the spoke holes
because of the design of the "wedges" that hold the spoke
nipples. Inflation pressure is not the culprit- and if it
was, such a limit would render these wheels at rather a
disadvantage for their intended purpose: racing and time
trialling. TTers like to pump those tires to 120 to 150 psi
in an effort to reduce rolling resistance. Any wheel
designed for this purpose should be able to withstand those
pressures.
