Tubular recommendations for TT bike ?

Lou D'Amelio said:

Hi - invested in disc (Zipp) and Hed-Trispoke tubulars for TT bike
this season. New to tubulars as I have used clinchers for everything
else the past 15 years. Although I'm generally familiar with the
respected lines, what do folks recommend for time-trialing ? Most of
my TT's will be 15 - 40 k on average to good roads, dry conditions. I
weigh about 170 lbs and am more of a masher than a spinner; so-so bike
handler. Bike is a Cervelo P2SL. I'm willing to give up a few grams
for puncture-proofing so not looking at the ultralite 150 gram tires
out there. From what I read, 22 mm profile actually more aero thasn 19
mm as they match rim better. Any thoughts welcome. Thanks in advance
for replies.

I think the Veloflex Criterium is a very nice tire. 22 wide, not as
delicate as the narrower Veloflex Record.

From everything I've read, using hard shellac track glue will make
them even faster, but I'm using Tufo Extreme tape with mine. I'm not
experienced enough to do a good glue job.

I suspect that tape is even worse than road glue in terms of rolling
resistance, and guing tubulars with road glue is easy. Just follow a
good set of instructions and you'll be fine the first time:.

Yes, it is. But for most of us, the difference is trivial. I use the
tape myself but I'm a heathen. I prefer Velox tape to tufo tape. If
you ride down hot mountain curves in the Summer at 75mph you can
potentially roll a tie.

For the OP, hard glue is the best.

Only if you brake.

....and achieve such speed in the first place, something not possible
on public roads, as has been discussed here often. In addition, tires
generally roll by going flat from heavy braking rather than cornering.
I experienced, that having ridden tubulars for about 30 years with
fast descenders, one of whom rode a spare tire that was not glued, as
we discovered later while mounting a new tire.

Depends on what you are riding. Ride something like the following (and
yes, the Coyote is ridden on open public roads) and 120 kph (75 mph) is
all to easily attained: <http://www.rotatorrecumbent.com/images/coyote.jpg>.

How steep a grade does it take to get a tubular tired three wheel
streamliner up to 75mph and how does it take "hot mountain curves?"

Poetic license on my part - You could potentially roll that tire at a
mere 65mph!

My point was actually that you have to hit some extremes to roll a
tire. I've never had an issue with using tape and I like the
flexibility when it comes to mounting a new tire on the road.

The Coyote is a bicycle, not a trike.

As for cornering, about as well as a normal bicycle that weighs 45 pounds.

I have found roads in Central Illinois and Southwestern Wisconsin where
I can exceed 50-mph on an un-faired lowracer with a relatively upright
seat. A fully faired bicycle would be much faster. In places like
Colorado with relatively long, straight descents, exceeding 75 mph on a
public road would not be difficult.

The Coyote body is made from the same molds as the Gold Rush that Fred
Markham pedaled to 65 mph in flat, no wind conditions.
