Continental builds its 4000 S II Tubular Tires with a puncture-resistant Vectran yarn casing. Vectran is a sort of super cotton, made from liquid crystal polymers 240tpi for a supple road feel that doesn't wilt under duress.
The 4000 S II may be mass-produced tires, but the legendary Black Chili Compound means they grab the road like a boutique model made by artisanal French craftsmen sewing tires in their backyard.
The casing is also seamless, which makes for a ride uniformity and impeccable tire seating that tires from those craftsmen simply can't match.
- Updated Black Chili rubber compound for low-rolling resistance and sensational grip and long life
- Vectran breaker belt under tread provides unsurpassed puncture protection
- Reflex tires have a reflective sidewall for increased visibility at night
