Continental's Grand Prix 4000 S Tubular is destined for greatness. The seamless casing makes it easy to glue the tire to the rim, and this race-worthy tire has all the suppleness and incredible road feel you expect from a handmade German tubular. This sew-up also boasts Continental's Black Chili compound and Vectran Breaker Belt, so you get increased puncture protection as well as superior traction and handling.
Vectran Breaker is a synthetic fiber modeled after spider silk. Processed into a multi-strand thread, it's light, flexible, and protects against cuts, without increasing rollling resistance.
Tubular tires are compatible with tubular rims and are installed with glue or a special adhesive tape. Tubular tires will not work on clincher rims (the standard rim type). If you have any questions about compatibility or mounting, please contact us for details.
