Continental Grand Prix 4000 Tubular Tire

The Continental Grand Prix 4000 Tubular is for those wanting the ride quality and handling of a tubular with the technical advancements of the Grand Prix 4000 series tires. The unique seamless casing design improves the rim seating, uniformity, and offers less rolling resistance. The tread pattern and compound are identical to the Conti 4000 S clincher tire.

The casing is wrapped 4 times using tightly woven 240 tpi poly-cotton fabric. It offers a very firm but resilient ride. Since there are no seams it glues to the rim surface with ease and with no hops and inconsistencies.

The tread is made from Conti's Black Chili compound. It is derived directly from Moto GP racing and offers lots of high end technology. It is essentially a blend of natural and synthetic rubbers. The natural rubber is mixed with 'nano' sized soot particles, who's surface properties are optimized to deform around surface objects and inconsistencies in the road for better grip. These small particles also form a tighter bond with each other improving compound strength for improved longevity and shear strength. Thanks to these polymers and carbon fillers, the Black Chili ends up being some of the strongest and most durable tread available as well as having the least amount of rolling resistance. The fillers also greatly reduce flatting.

Under the tread, Conti has placed a strip of Vectran which adds to the already out standing puncture resistance. It is essentially a protective belt made of super strong and extremely lightweight and pliant material. Small wear levels indicators have been molded into the tread to measure wear.

    A fantastic tire for a number of differing conditions. I have ridden this tire in Roubaix-style routes, newly chip-sealed roads, on hard crit courses, and long training rides. They are grippy and fast. However, they do wear FAST. You get a great cornering tire with superb grippiness, but expect to get between 500-700 miles off the tire. As a further note, Conti tires in general are somewhat difficult to mount. So, i suggest a lengthy "cure" period of inflation at high psi prior to mounting on the rim (if you have the time).
