Any thoughts on the Shimano carbon wheelset? How does it compare to the Rolf Prima Elan, American Classic 350, or Campy Shamal?
Thanks.

Shimano's wheels are superb. Stiffness is probably the strongest suit of the high end Shimano wheels. Roulanes-Artistans' wheel tests have put the tubular Shimano wheels near the top of the charts in terms of stiffness. Long term durability with the high end Shimano wheelsets have been pretty favorable in recent years.
The 7850-24 CL hasn't been on the market for more than a few months and not a lot of people have ridden them as they have been very scarce in the states. But you can probably expect a very durable wheel with superb hubs that's pretty close to its advertised weight.
How does it compare to other wheels?
I can first and foremost tell you that American Classic product is not worth spending your money on. There are so many reports of failures, poor customer service and other poor experiences with American Classic product over the years your money is better spent elsewhere.American Classic is light and cheap but its not strong. Not even made in America either(although that doesn't matter, but its some false advertising on their part).
Campy makes superb wheels with absolutely no downsides other than cost and angering the cycling Gods if you mix them with a Shimano drivetrain.
Rolf Makes good wheels and the company has a great reputation. I don't think their paired spoking offers any benefits other than looking cool.
I'd rather have the loose ball setup in the Record or Dura-Ace hubs than the sealed bearings in the Rolf wheels.
That's my two cents.

Shimano warns of puncture prone Dura-ace
Mark Sutton Oct 8 2008, 11:06am
DURA-ACE clincher tyre wheels WH-7850-C24-CL and WH-7850- C50-CL affected
Shimano has found that there is a greater likelihood of a puncture in DURA-ACE clincher tyre wheels WH-7850-C24-CL and WH-7850-C50-CL. This is due to the surface texture of the rim in combination with the use of spoke-hole plugs.
The phenomenon can be very easily eliminated by replacing the spoke-hole plugs with genuine 18 mm high pressure Shimano rim tape.
At the website http://cycle.shimano-eu.com an instruction can be found about replacing the spoke-hole plugs by rim tape.
All Shimano clincher wheel sets will be delivered with Shimano
rim tape as of now. Dealers are instructed to supply Shimano rim tape free of charge to consumers affected by the problem, for which a refund will be available from Madison who have been sent replacement stock.

i have the 7850 sls. for me these are on the nice bike and are everyday wheels on that bike, im not interested in race only wheels. the sls have a different, all aluminum rim. i enjoy these wheels alot. i kinda wanted to get the cls for the carbon bling factor and the 100+/- gram savings, but the sls came with my bike.
i love them, stiff and strong, truing a slightly difficult, but i only had to true mine after a break in period. the tubeless which the cls lack(?) is really nice, make them feel like a carbon wheel. the freehub is really quiet.
i really like the wheel offerings from shimano,

actually theyre aluminum alloy rims, they have scandium in them yes. alloys with scandium have by weight .1 to .5% scandium.Dr_John said:
calling the rims on the 7850 sls a 'scandium rim' to me would be like calling an aluminum alloy frame with trace amounts of zinc in it a zinc frame.
it is nice and cool from a marketing ploy, but not true.
scadium oxide costs about $1,500 a pound (via wikipedia)

As the poster above stated they are aluminum. Almost all aluminum used in the world is doped with various metals such as copper, zinc, magnesium, vanadium , manganese, silicon and occasionally titanium and niobium.Dr_John said:
These elements are present in very minute quantities in the aluminum.
Scandium is just a marketing buzzword for a high quality aluminum alloy.
I just got the Shimano 7850-C-24-CL Wheelset upgraded from 7850.All I can say is hell ya!!!! Thease wheels ROCK! Stiff ,Light at 1390g. Im 195lbs and ride very rough roads and have no probloms with my old 7850 or my new 7850-c. Im going to use stans yellow tape and put some tubeless tires on like my 7850s.
I also just bought a set of WH-7850-C24-CL. Build quality is very high. Bearings are superb, they roll silky smooth - better than anything else I've tried. Regarding Rolf, I've use them for a number of years. Rolf hubs are good, but wheel and spoke durability is not so good, at least for my 83kg weight.
Next up, the tubeless version. I'm saving up already.

Dr John,
I always appreciate your comments.
Any idea when Shimano might release them? I've had a 2008.5 Tarmac Pro w/ the Roval Fusee SL wheels since the end of July and will probably ride it recreationally for fitness (I like the rush!) 5000 miles / yr. After being off the bike for 20 years, I'm working to get stronger in the rolling hills of San Luis Obispo County (CA).
Any ideas as to what I might gain?

No idea. I'm not even sure they're a reality, but it seems like their next logical step. It took quite a bit of time from the announcement of the C-24-CL's to their general availability, so I'd guess they're a long way off.
I'm a climber, and I love the ride of the tubeless 7850-SL's I have, so a C-24-CL tubeless would be the dream wheel for me. All you'd really gain is tubeless capabilities.
7850 c24 CL VS 7850 SL
hi.
can someone compare for me:
-7850 c24 cl
-7850 SL (tubeless).
who rode these 2 , and could compare it regarding comfort ?
i doubt, that the SL rim is as comfy as the c24... can u feel this or not?
i want to ride tubeless.. c24 could be "stan-taped"

Just bought the c24-cl's. Haven't picked them up yet, but am expecting good things. Here's what one very helpful shop tech said when I asked why they seemed relatively unavailable in the U.S...
"That’s possibly the single most underated wheel in all of cycling, and the only reason they don’t sell is because the morons at Shimano couldn’t market their way out of a wet paper bag.
They’re light as hell, and laterally they’re stiff as a set of Mavic Ksyriums. BUT BUT BUT they ride like a pair of traditional handbuilts: silky smooth. I say buy a pair, and beat them to death. You’ll absolutely love them, and like me – wonder why EVERYONE isn’t riding them.
Don’t sweat the rim tape thing – just grab some Velox and you’re good to go."
My LBS also suggested that they don't have to market here in the U.S. like they do in Europe. Here, they rely on their good name. There, they have Campy etc. to compete with.
