I also tend to doubt that 1-G cornering forces are going to be held by the little rubber bead features; seems flimsy. Give me glue, tape, or real beads.

It is a tubular, but it's not a very good tubular. If you get some for free, fine. But it's not something one should spend money on in general. better would be to just get set up for a real tubular, or get the latest Michelin clincher race tires in your preferred size.
