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.
In 2003 Challengetech created its own brand “Challenge”. Challenge, as the word says, wants to point out how difficult and exciting it is to keep the tradition of high quality products, created with obstinacy, with the steady research of special materials and through handcrafted processes. Since the 2000s, Challengetech has being producing tubulars for other brands, thanks to the constant use of these products in the professional cycling.
