Tubulars mount on different rims than clinchers, so you can't swap them. Many manufacturers use the term 'open' to mean 'clincher'. There is no such thing as an 'open tubular'.
Tubulars also are mounted on '700' rims, but some manufacturers still call the size '28 inch', an old-fashioned standard. When a tubular specifies a width, it is usually accurate.
Tubulars are a self-contained tire, including a tube. Most (aside from Tufos) are sewn together, all mount with glue to the rim.

Oh, boy, where did you grasp all these wrong ideas? I don't blame you since you are new.
OK, fellow students, seeker of knowledge, today we are going to talk a little about road biek tires:
There are two types of tires: clincher and tubular. The two are not compatible, each require rims designed just for its type.
The tubulars are basically a closed tube, they are the old type of tires, today used only for racing bikes. You need to glue them the the rim for mounting, and if you have a puncure, you need a new tire: rip off the old, scratch the rim clean, then glue the new one on it. Really costly, pain in the butt to mount. Some racers still like them saying they roll better, and you can still ride even when you have a puncture.
Clinchers are what majority of people use now, they are more like a cover to wrap tubes inside, if you have a flat, all you need to is just put a new tube is in, cheaper and faster. The clinchers have improve tremedously over the years, now many pros are using them now, so they can pretty much match tubulars in performance. I see no reason for a newbie to fall in love with tubulars
As for sizing, do not worry about width, just remember the number 23c. There are two different size of wheels: 700 and 650. The number refers to the diameter of the wheels in centimeters. 700 is found on all road bikes, 650 is for triathlon bikes only. (For people who wants to correct me here, I don't consider them time trial bikes).
So now, go home, buy a pair of 700*23c as assignment for today. I'll check your work in next class.

hahahaha....THATA WHERE U ALL ARE WRONG!!!!

THERE IS SUCH A THING AS OPEN TUBULAR....it is really a tubular that can be used on a clincher.....prpoerties similar to tubular but with bead for mounting!!!

check www.guerciottishop.com....under tyre tech and u know wat i mean....guess all of u need remedial lessons!!

Where did you come up with the idea that changing a flat clicher is faster than a tubular? Have you actually had any experience riding tubulars?

I only ask because changing a tubular on the side of the road is hands down faster than changing a clicher and I've never ever heard anybody claim otherwise. Additionally, I've also never heard of anybody scraping the old glue off of a rim after a puncture? Why would you do that? Just glue the new tire on (your spare should be a tire that already has glue on it). The only time you need to clean the rim is when it is brand new and you are gluing it for the first time.

Here's a really good reason for a newbie to fall in love with tubulars: If you blowout a clincher while moving at a high rate of speed, you are probably going to hit the pavement. If you do the same with a tubular, it will not deflate instantly like a clincher usually does and since you can ride on a flat tubular, you have a chance of staying upright.

No, tubulars are STILL used by THOUSANDS of road bike riders, not just racers.
When you have a puncture with a tubular, unless you are made of money, you eventually FIX the d@mn thing. Yes, it's a pain at first, but anybody CAN patch a tubular in 20 minutes, once they learn how to sew them back together.
Scatch the rim clean? What planet are YOU on? When you have a puncture on the road, you put a PRE-Glued tire on, to replace the flat one.
Of course, you wouldn't know, since you obviously don't ride tubulars. Please leave the advice to those that actually do.
P.S. There are many small-frame road bikes that use 650 rims, not only triathalon bikes. 700 rims are actually 622 mm in diameter, and I belive that 650 rims are 597mm. Notice, the measurement is millimeters, not centimeters. Three more things that you got wrong, Mr. Know-it-all!

Wow! wheels the about the size of 2 story building!
Wonder what the gear sizing would be...
