Bottomless CL Day!
Sick deals back to back all day long.
Nice job CL. Trying to get me to spend my money!!!!! Sombrio, Royal...doing good with the clothing.
I need a paperweight for my desk!
To all 28= 700c normal tubies
The 26 are 650c (tri,womens, etc)
Tubular Tires ("Sew-ups")
Tubular tires are mainly used for racing. A tubular tire has no beads; instead, the two edges of the carcass are sewn together (hence the term "sew-up") with the inner tube inside. Tubulars fit only on special rims, where they are held on by cement.
Tubulars existed in 6 different sizes, but only two of them are readily available these days.
* Full-sized tubulars fit rims of the same diameter as 622 mm (700c) clinchers. This size is sometimes referred to as "28 inch" or "700". It is also, confusingly, sometimes referred to as "27 inch." The "27 inch" designation is inaccurate and obsolete, but you'll sometimes run into it in older printed material.
In clincher tires, there is a real difference between "700c" and "27 inch" sizes, but for tubulars this is a false distinction. Whenever you see mention of "27 inch tubulars" the writer is actually referring to standard full-sized tubulars, as used on most racing bikes.
* "26 inch" or "650" tubulars are smaller, mainly used on time-trial or motorpacing track bikes.
* "24 inch", "22 inch" "20 inch" and "18 inch" tubulars are sizes formerly used for children's racing bikes, but pretty much extinct these days.
Tubulars are also sometimes called "sew-ups" or "tubs" (British usage.)
If you want to sound like an ignorant yahoo, call them "tubies" or "tubeless tires."
The above from Sheldon Brown.
To reduce both air resistance and rolling resistance on the road, tires are lightweight, narrow, and have a thin, smooth tread. They are inflated to a high pressure, typically around 8 bar (820kPa/120psi); track racing tires can be inflated up to c.14 bar. Until recently, most racing bikes used "tubular/single/sew-up" tires which have no beads: they are sewn around the tube and glued to the rim. These tires provide an advantage in weight (lacking the relatively heavy wire bead), rolling resistance, grip and pinch flat protection, but their greatest advantage lies in the ability to use a very lightweight simple box-section rim, rather than the U-shaped clincher rim. A U-shaped clincher rim must use relatively heavier gauge to prevent the tire pressure from spreading the inherently weak U shape and allowing the tire to come off the rim. Advances in tire technology, however, have seen the far more practical (due to greater ease of changeability) clincher (beaded) tire close the gap. Some manufacturers create Tubular-Clincher tires, where the tires are sewn around the tubes and have a bead, but there is some debate as to the effectiveness of a tubular-clincher tire. Proponents believe that it has all the advantages of a tubular tire made to fit a clincher rim, but critics argue that the design includes disadvantages inherent to both systems---the rim weight is still high, the tire is more expensive than a standard clincher tire, and repairing a puncture on a tubular clincher is as inconvenient as it is with a standard tubular tire. However, a particular benefit of the tubular-clincher design is that the risk of pinch flats is very low (like the tubular tire), yet it allows the use of the more popular clincher wheel.

are actually 650's not 26" (maybe the measurements are the same?) Check Conti's website for further confusion. Appearantly there is a 28 size as well. (Maybe this is 700c?)
Well, check it CL! http://www.conti-online.com/generator/www/de/en/continental/bicycle/themes/race/competition/competition_en.html
I see the 26" and wonder if that would be close enough to qualify as a 650c tubular. Hummm... too cool (rich) for my blood, regardless.
At least I hope not as I would ream out the MTB'er rollin with these racing slicks! I'd say they are probably 700c X 19 or 22.
Really though, these should be replaced by good clinchers, as not all that many people run tubulars with the advantages of modern clinchers.
oh...you were asking for men's not about the women's...
If you're asking about the Pearl Izumi Select women's shorts, I have these with green accents instead of orange and they are way comfy. I use them for mountain biking. I can't tell if these have a drawstring or not- mine do and I like that.
These look like nice shorts, any chance of putting some mens up there?
i guess they just don't exsist
I wonder if these Sombrio gloves will give me both protection AND the tactile feeling I'm looking for? Is it like wearing nothing at all? It also looks rather fragile for a "freeride" glove. Sometimes you need extra protection when you're running up in those nasty skanky.. uh.. drops you know?
