Challenge Pista 700x23c Open Tubular Track Tyre Black/White

What's the point in training until you drop if you're going to be losing efficiency and speed in your tyres? Ride quality is paramount, and no other tyre offers the supple, responsive traction of a Challenge Open Tubular. To be more precise, no other tyre eliminates barriers in achieving your maximum speed and potential like the Challenge Pista SC Series Tyre. Both strong and light it can achieve amazing things on wood and cement tracks. When speed is key and you have no time to think, Pista is definitely the tubular to rely on.
Intended for Track racing and featuring a Corespun cotton casing it has become a favourite of world-class athletes due to the light and supple material that maximizes their comfort, control and performance. For compatibility with ETRTO standard clincher bead rims the tyre includes a lightweight Aramid bead. The extremely high value of threads per inch (320 TPI) that Corespun cotton can guarantee makes this tyre extremely light and capable of superior performances. It can be installed on a rim for clinchers with inner tube and is best suited to road racing.
What is an Open Tubular?The Open Tubular is constructed using the same process, casing and tread materials as a standard tubular. The difference is that 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. An open tubular can be installed on a rim for clinchers with inner tube.
