Tubular tires, often called sew-ups in the U.S. or a "Single" in Australia, is a tire made by sewing a cloth casing around an inner tube. This tire is then glued onto a concave rim.

Countless bar fights have been started over the advantages of tubulars versus clincher tires. We believe nothing rides as well as a hand-made bike fitted with tubular tires mounted on a traditional small cross-section sew-up rim.

But, this wonderful ride comes at a cost. Sew-ups are difficult to repair. The rim strip, which is glued to the tire, must be pulled away, the stitching near the puncture undone, and the tube patched. Then the tire has to be re-sewn and the rim strip re-glued. Plus, modern "Open Tubulars"—clinchers fabricated with all the techniques that make a tubular nice to ride—approach sew-ups in ride quality.

Plus, clinchers are much cheaper.

But, as we said, nothing rides as beautifully as a fine bike with wheels made by a skilled wheel-builder mounted with hand-made tubular tires.
