Mark Cavendish sprints on them, Tim Don trusts them in World Cup Triathlons and Nicole Cooke is also a fan. The latest Competition tubular features Conti's Black Chili compound, which increases grip whilst lowering rolling resistance without affecting wear - truly phenomenal! One layer of the cut resistant Vectran under the tread instead of the previous two nylon breakers reduces weight and improves rolling resistance and rolling comfort. The German manufacturing process of the Competition hasn't changed. As previously, the worlds best pros only trust the handmade production of Continental's seamstress team and their production staff in Korbach.
