Specialized "turbo" series clinchers can be folded like tubulars, since
the bead is reinforced with a Kevlar cord, rather than a metal wire.

Also, I believe the word "clincher" is actually out of date;  real clinchers
(I think) didn't have any kind of wire in the bead, but the rubber was
shaped around the bottom into a notch with mated with a complementary
cross-section on the rim.  Beaded tires were the next evolutionary step.
