Open Tubular (Clincher)

An open tubular is constructed using the same casing and tread materials and process as a tubular, but instead of sewing the casing together (closed), the sides of the tubular casing are folded around aramid fibre cords to produce beads. This ‘open’ design performs like a tubular, yet conveniently mounts like a standard clincher tyre. 

If combined with a Latex inner tube the ride becomes even closer to that of a tubular, offering excellent traction and cornering, low rolling resistance and shock absorption.
