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.
