Challenge Grifo Pro 700x33c Open Tubular Cyclocross Tyre Black/Brown

The Challenge Grifo Open Tubular/Clincher is the best-selling tyre of the Cyclocross line. With low rolling resistance on dry pack plus great grip and cornering when necessary it's a true all-rounder. This tyre combines an extremely high value of TPI (300) with a really low weight (373g) to make it an ideal product for professional riders. The great thing about this hand-made tubular cross tyre is that being an open tubular it can be installed on a rim for clinchers with inner tube without having to fuss with rim glues and time-consuming clean-ups' afterwards. Whether you're a Pro or just a hard core enthusiast, Grifo is the tyre you need.

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.
