Are there any decent time trial wheels that are not tubulars? everything I have looked at seem to be tubular. Campagnolo Bora/Ghibli, Rolf Carbons......

I don't know if they are the kind of quality as the wheels you have listed, but they are offered on a clincher rim. Also, if you're looking at Campy Bora's, the Shamal rim is nearly the same profile and offers the same aerodynamics. It is available in a clincher option. Check out Mavic also. The Cosmic Carbone is available in a clincher rim.

Good luck!!

My appologies as I have just looked at the specs of the Bora vs. Shamal. The Bora rim is 50mm deep, while the Shamal is 38mm deep, so there may be a significant enough difference in aerodynamics between them.

If you can get your hands on an older 12 spoked Shamal (silver rim) it is 50mm deep as oppossed to the newer black rimmed model.

Take a look at their website:

http://www.hedcycling.com

However, it does appear the site may be outdated, as they discuss the introduction of a 1999 9-speed campy splined cassette body on their disk hub. Who knows, but the site also offers direct purchasing of their products.

I bought some wheels direct from HED. Give them a call at the number listed on the site and ask what they have (I don't think the "HED shed" has changed in quite a while). Nice folks to deal with. I ended up with a HED3 front and a HED DEEP rear, both clinchers. I think the total cost was right around $600. I may upgrade to a disk in the near future. When I do, I'll go back to HED.
Question about your HED 3 front wheel . . .Andy

I am looking at a HED 3 for my TT bike. How does it handle in gusty cross winds? Our time trial course is flat as a pancake on the edge of a lake so it's more often windy than not. I have a disc wheel on the rear.
Not too bad.Lazy

I've been moved over a few inches a couple times when I was caught by a surprise gust, but nothing serious. Overall, I'm pretty happy with it. No complaints.

The Hed wheels look good, I e-mailed them and asked about a H£ front and rear but they don't cater for Campy 10 speed.....such a shame....

... both HED and ZIPP make nice aero clinchers as well as tubulars.

... both companies are small enough to be generally accessable directly by the consumer... a nice touch in this day and age.

HED wins on costs, giving up a bit in weight... ZIPP's are lightweight but will cost a bit more.

There are other smaller aero wheel designs/makers out there, but these are the only one's I have any experience with.

Be the bike.
you WANT Tubular TT wheelsstr8dum

The entire point of TT wheels are to get narrow tires (20mm or less) and pump them up to 150+ psi.
Cant do that with clinchers.
also you can ride a flat tubular to finish the TT whereas you can't for a clincher

Also, if they are TT wheels, dont bother with anything besides a disc in the rear.

There are many clinchers available in 20mm and narrower that can be pumped to 150 psi/10 bar. Last time I checked, if you flat in a TT (unless it is only 50-100 meters from the line) your time is in the toilet anyway, so the supposed ability to ride a flat tire is not worth much. This isn't a rant against tubulars - just to point out that, as in all other cases, the differences between clinchers and tubulars is not that large. No reason to make unreasonable and unsupported statements.

I'd say the biggest difference between tubulars and clinchers right now is the wheels available for each. There are some very lightweight carbon wheels that are just not available in clincher, or at least are a bit heavier in clincher. If you want the (arguably) fastest wheels, you gotta go tubular.

And, yes, the difference is fairly small.

Set of Lew wheels @ $1,100 will knock you back a bit, for example.

Surely you only want a disc rear on a flat course? alot of my TT courses are rolling which I deliberatly go for as I do better on rolling courses than the flat courses. I'm small and light but probably not ever so powerful! I was thinking more of tri spokes or a trispoke front and deep section rear (like a HED deep 90). Also, clinchers like Conti GP supersonics pump to 145 psi, that's plenty hard enough!
