Black Beauty - the completely black Cambium C15 All Weather, made from natural rubber with a weather-resistant nylon cover, is the sporty version of the Cambium series. Its construction is based on the principle of a hammock, providing excellent cushioning properties. The C15 All Weather offers immediate comfort and a relaxed riding experience without a break-in period. The Cambium Carved version of the C15 All Weather features a relief opening that reduces pressure in the seating area and enhances comfort on longer rides. The additional flexibility absorbs shocks and vibrations from the road exceptionally well.
