|Which wheelset would you prefer for sport touring, training, century, etc. use?
PS -- The "upgrade" to the Cosmos will run me $130, if that makes a difference in the analysis.

|I'd take the Chorus/Open Pro over the Cosmos, especially considering they're that much cheaper. Keep in mind, the Cosmos don't come with an ED10 freehub- so you'll have to use some weird cassette to make it work with Campy10.
Regardless of the cassette situation, the Chorus/OP is just a better wheelset than the Cosmos- all the way around. The Open Pro is a better rim than the Cosmos has, and the Chorus hubs, particularly the rear, are equivilent if not an improvement.
|so what the diff. in rims apart from spoke count? nm||naff geezer|

|The Open Pro rim is made out of Maxtal (an 'exotic' 6000 series aluminum), which, depending on who you believe, is either 30% stronger than the same rim made with standard aluminum, or is a fancy marketing term.
But, for those older in the audience, Maxtal is the difference between the old Reflex clincher rim and the Open Pro rim. And the Open Pro has proved stronger and more successful than the Reflex was. The Cosmos effectively uses a lower spoke count Reflex rim.

|I believe that the Mavic hub in the Cosmos and "Elite" wheels uses a Taiwanese freehub body instead of the higher quality Mavic freehub body. That would make Cosmos the rough equivalent of low-end Rolftragers or Ritchey wheels; you'd be paying more and ending up with partially Brand X hubs to boot.|
|I think it's French,||TJeanloz|

|I don't think it's a Taiwanese freehub, but it is certainly not top Mavic quality. The bearings are all the same (Mavic really only uses one bearing design) but the freehub weighs a ton. Regardless of where it is made, it is sub-par when compared to Campy Chorus.|

|I train on Open Pro's with Chorus hubs and I love 'em. They're reasonably strong and light and they're also easy maintanence. It's certainly easier to replace a spoke on traditional wheels than it is on a "wheel system"! For the type of riding you're describing I'd say save your money and then have some fun finding some other cool little upgrade to spend your money on!!|

|I have no experiemce with Cosmos but I use the Chorus/OP combo. I'm hardly a lightweight as I'm on the far side of 200lb and find these wheels to hold up fine and roll really smooth.|

|I have a set of Cosmos and love them. I belive the Cosmo rim is pretty much an OP. The sealed bearing are great and have a smooth roll to them. Also the straight pull hub design makes it very hard to break a spoke. Im not sure how they work with Campy parts. And Im not sure if the price difference is worth the money, but I think they are a great wheelset.|

|I have a pair of Open Pros with chorus hubs. Ran into the back of a car while doing about 18 mph. My Bianchi chomoly frame was bent both on the top tube and down tube. Toast.
My front Open Pro, which took the full force of the impact, was still true.
They were built by Sdeals in England. They're not Nucleons or Zims or the-last-gram-fastest wheels, but as a general purpose set of wheels, they are hard to beat.
|wow - you did the the ultimate "test"||PdxMark|

|Hope you were OK. I must admit, though, that as a wheel durbility "test," your post gave me chuckle... Buckled frame and the wheel not only survives, but remains true...
I ride the same wheels, with just 2000-3000 miles on them. I like them alot, but can't add anything approaching your testimonial...
The closest is I was driving back from a ride with a couple friends, our bikes on the roof, mine in a rack with a down-tube gripper. Driving along the freeway, I looked out the side window to see my handlebars out the side window... The downtube gripper had slipped, and my bike fell over, being held just by the straps around the rims. Wheels remained true...
The dumb part was that I carefully reset the bike in the rack when we stopped, and it fell over AGAIN!!!... wheels still true... bike came inside the minivan after that...
no experience with cosmos rims

|chorus w/OP is a good choice for your riding needs-- besides that gives you $130 towards a "gaudy" but beautiful cobalt blue, kelly green/tropical yellow swirl paint job...*S*|

|i have used both -found the cosmos wheelset
gave a harsh ride especially the front
with the chorus/op you can choose spoke patterns
to suit the type of rides your aiming to do

|here in the uk cosmos kick off around
£130(sometimes less) whereas op/chorus
would cost at least £150

|Go with the OP and upgrade to Record hubs. The grease ports are worth every penny, even if they did not have smoother bearings.|
|even better than both of those||CT1|

|Get the Chorus hubs with Aerohead 2 rims and Revos all around except the drive side. I've built a bunch of these and they are very sweet.
FWIW: I've also owned Chorus + open pro wheelsets and they work fine. I just don't think they're any better than the Aeroheads and their more expensive.
Oh, My CT1 is built and it's got a pretty awesome ride. Probably the best handling and riding bike I've ever been on. Maybe even better than my LOOK ..... which is saying a lot. I'd post a review but the shithead kids would post crap all over it so why bother. If you want my honest comments just email me.
