The Tempo II is Continental's basic offering in a high-performance tubular track or TT event tire. The durable and fast Black Chili rubber compound ensures that the Tempo II has exceptionally low rolling resistance with phenomenal grip in wet or dry circumstances, across the entire rubber surface. Along with proprietary synthetic and natural rubber compounds, the secret to the properties of Black Chili comes from special nanometric carbon soot particles, which are optimized in shape and surface properties for each tire.
