Since I discovered that a tubular tire will fit on a clincher rim I often carry a spare tubular in case a clincher gets ruined. I also carry a spare tubular when on an organized ride so that I can give it to anyone who needs a tire.

When I rode the bike with the tubular tire on the clincher rim to the bike shop the guys working there were quite surprised that it was able to be done.

Someone on these forums said that one should watch for chafing of the tubular tire by the rim of a clincher wheel if riding a tubular tire for any great distance. I've never had any problems with the distances I've used.

This using a tubular tire on a clincher rim came about one day when I went to ride my bicycle and discovered a very large bulge in the tire due to having it a wide gap in the road the day before and severely damaging the clincher tire on it. That tire was ready to blow so in desperation I tried putting an old spare tubular tire i had here on it. It worked and I was able to ride to the bike shop and get a new tire.

Cheers
