OK, i'm doing a comparison between some deep"ish" carbon wheels.
Must be clincher with alloy braking surface and 40/50mm deep.

1/ Anyone know the difference between Simano Dura ace WH 7850 C50 and 7900 C50's (apart from the price!))

2/ Shortlist is

Zipp 404
Cosmic Carbone SL (noisy and just a carbon fairing on a standard wheel?)
Dura ace 7850 C50 or 7900 C50 (See above).

Any views considering the price differences?

on your other point, think the 7850 are newer as they are the only ones on the shimano site and they have the trendy red anno nipples, but otherwise seem to be the latest duraace???

google wheelsmith, they have even the enve which look great as well

i had the same issue as you and eventually plumped for the planet-x carbon rim tubulars instead! I worked out that @ 1296g the pair and £500 i could put my principles aside and go tubular (i do these things to myself every so often, they usually work out OK and that is how i made the jump to carbon frames as well...)

i still agree in principle, clincher is the way forward, and my head tells me alloy is better, and TBH the zipps seem to be the best incarnation of this, but the price begs belief, and they are still not coming in at 1296g

i will ride these with continental competitions this week, cannot wait TBH now I have my apprehensions aside (the best part of an extra grand in my pocket helped!)

What happens if you get a puncture on your tubular though? I want to be self sufficient on the road which is why i want to stick with clinchers. Like the idea of 1296g wheelset but doubt i am going to get that with clincher rims

I'm looking at medium depth rims too. Dura-ace 7900 C50 are the latest model and are a bit lighter than Dura-ace 7850 C59. About 150 grams lighter.

If you want an aluminium braking surface the DA 7900's are the way to go, unless you can afford/justify Zipp 404's.

My shortlist includes the DA 7900's, Reynolds Assaults, Williams System 58, American Classic 420 aeros.

Hadn't thought about American classics or williams system so will have a look. Have now shortlisted following my post to the DA's or 2nd hand zipps.I did look at the Reynols assault but seem to be a few reviews around about broken spokes and even some rim problems so i have binned them from my shortlist. So 2nd hand zipp's or DA 7900 c50's. just need to find the cheapest and compare against the £1100 or so for mint 2nd hand zipps
Anyone know the cheapest place for the DA's 7900 c50?
