I've been reading some of the tubie vs. clincher discussion going on here, and I'm tempted to try them out if I can find a set of cheap wheels. I've only ridden on clinchers, and had a question:
All of the tubulars I've been able to find info on are < 23 mm, usually 21 or 22 mm. I am about 220 to 225 lbs and ride on 25 mm clinchers. Am I too big to ride on tubies? Should tubie width not be compared to clincher width?
I started out on 23 mm tires inflated to about 120 psi, and once in a while someone would tell me my back tire was going flat. So I moved up to 25 mm @ 120 psi, and those comments stopped. I also like the ride better.

Moderately ample 25mm tubs have virtually disappeared. There are nice 27mm Paris Roubaix but not much in between.
(A true 27mm tub won't clear some modern race bikes under the caliper.)

I answer-A decent 23mm tubie will work fine. I am 'almost' your weight and ride them every dry day.
Use about 110psi and go enjoy how nice the ride is and also, you won't be called a 'girly-man' for using clinchers.

If you just want to try them, nice tub wheels turn up at swap meets cheaply this time of year.
I see one of the problems with tubulars hasn't been mentioned here but most rims have a semicircular contour on which the tubular tire rests. The radius of this contour should match the tire size fairly accurately or the tire will walk more than one might expect. The rims of the 1960's and before of Fiamme, Nisi, Martano, Mavic and others were a compromise in having a smaller radius in the center and a relatively broad curl toward the outside.
A 23mm tire seated best on Fiamme rims while the 25mm road tires, Campionato del Mundo and Speciale Corsa sat a bit high on the edges of the main radius. This is one of the reasons they wore out from beneath and why adhesion was not even as good as the glue should have offered.
So what are the current rims offering as a seat radius? I'm sure this problem has not disappeared.

I have 2000 Lemond Tourmalet with Sora brakes. I'm guessing 27mm would be kind of close. I have 25 mm Conti GP 4 seasons on right now, and it looks like there is about .25 inch clearance between the tire and the calipers. On the front, it looks like the fork is the limiting factor, it is closer than the brake calipers.

Around here, that's a hangin' offense.
