"What the heck is a "rigid tubular?" I was just poking around the Bikeinn site and quite a number of the tubular tires listed are described as "rigid." For example:

I have no idea what a rigid tubular might be and would like to be relieved of my ignorance."

My unverified conclusion when researching this a while back was that this is a description for a wired on clincher which takes a tube as opposed to a folding clincher or a tubeless clincher tire. I believe many discounter/surplus/ebay/amazon sellers' descriptions cannot be relied upon, particularly with respect to the word "tubular." I also note that the spelling of "tyre" suggests a non American seller whose definition/understanding of "tubular" may vary from that of an American. In any event, I decided not to take a chance.
