The Service Course SL-Carbon seat post is designed to be more shock-absorbing than the comfort seat posts available on the market while still passing our rigorous internal MTB strength test. The integrated flex in the lightweight carbon tube ensures comfort for the rider in any terrain. A better seating position means better performance, and when the saddle is not in the correct position, energy is wasted with every pedal stroke. The secure two-bolt clamp allows for easy micro-adjustment of the saddle position, and the head has been redesigned for maximum accessibility of the screw head. With options for 0 mm and 20 mm offset, it is possible for almost any rider to find the perfect position, and the clamp works with all types of saddle rails.
