When you have a flat they are much faster to fix. Just rip the flat
off the rim and stick on another from the collection you have strapped
under the seat :-)

Have you ever fixed a tubular on the side of the road? Or even in the shop at home? No one just rips off the flat tubular and quickly sticks the new one on the rim. Does not happen that way in the real world. Maybe in fantasy land. Tubulars are glued on very well. It takes a lot of pulling and prying to get a little bit of the tire off the rim. Then a lot of strength to slowly pull the rest of the tire off the rim. Several minutes of work or more. Then to put the new one on, you better pray it is well stretched on an old rim. You start at one side and slowly work it onto the rim with old glue. Slowly pulling it on. Then the last few inches you strain and stress until maybe hopefully you get it on. Then you spend several more minutes trying to get the tire somewhat straight on the rim. The old glue does not allow the tire to be moved very easily. Keep living in your fantasy world.

I can change the tube in my clincher tire in less time than he changed the tire on that rim (not counting the time he stopped to explain) and when pumped up I don't have to worry aboutthe tire rolling off the rim in a hard turn like you do with an unglued tubular.

The great thing about being able to change a tube on a clincher tire is that when it's done you have the SAME ability to ride the bike as you did when you left for the ride.
