it's not common nowdays, but 27 years ago, most good bikes came equipped with tubulars. Once good clinchers were available (i.e. 90 psi and 1 1/8" width), a lot of folks decided to build up a set of 27" clinchers to supplement or replace the 700C tubulars that came on the bike. The clinchers weren't as nice as a good sew-up, but were a whole lot easier to patch.
