Clinchers for time trials?

What're some good clincher tires for time trialing? I have
Specialized composite wheels on my TT bike.

Advisory was at: <hedcycling.com> Google for recent thread
here. A Conti tire I have (sorry, in the middle of a move
here) was a good fit; i.e., smaller bead than other tires,
seemed to fit better into the small bead recess in my
Specialized Tri Spoke. Another tire's bead (one mentioned in
the advisory) was so much bigger that only about half of the
bead fit into the Specialized rim. I'm guessing this has
something to do with blowoffs especially at *excessive*
pressures. (Flame suit on). Anything over 120lbs. (Goggles
up, air on). --TP

I'm considering the Continental Supersonic and Vittoria
Ultra Speed. Are there others?

I've heard a smooth tire is better than one with a tread
pattern. I've also heard a feather edge transition between
the tread and sidewall helps aerodynamics. Makes sense to
me; is there any data to back this up?

You want the lightest, most flexible carcass you can find. I
like Specialized Turbo folding tyres, but the particular
type that I've stocked up on is no longer made.

Thanks!

I'm on the Conti's (GP Supersonic, 700x20) and I don't think
they're holding me back :-)

Michelin Pro Race Iron Man. I have had great results with
this tire.

Cycling Plus reported that the Vredestein track clincher was
the best rolling tire for TTs, according to their test
procedures. Avocet makes a 23 mm TT specific tire with very
supple casings and really thin rubber.

A tread pattern is just for looks and has no benefit for
riding on paved roads. Some of Greenspeed's rolling
resistance test results, as posted on their Website, suggest
to me that some tread patterns can increase the flexibility
of the tread and help reduce rolling resistance somewhat. At
least that's the only reason I can think of for some tires
with thick-ish rubber having good results (other than
measurement error).

It's only useful if you need that 0.0025 seconds for
victory, your position on the bike is as optimized as it can
possibly be, and you are already trained to your absolute
maximum potential. Otherwise you're splitting hairs that are
of no account.
