Fixed bike seatposts

ZIPP Service Course SL seatpost, 20mm Setback, 27.2mm diameter, 400mm length, with matte black logos. The Service Course SL carbon seatpost is specially designed for more shock absorption than the "comfort" seatposts on the market, while still meeting Zipp's rigorous internal MTB component durability test. Flex built into the carbon tube with a low weight allows the rider to enjoy a comfortable ride on any terrain. A better position on the bike means more performance, and when your saddle is out of position, you lose energy with every pedal stroke. The secure two-bolt lock allows for easy micro-adjustment of the saddle position, and the "head" of the seatpost has been redesigned for the easiest possible access to the bolts. With an offer of 0 and 20 mm offsets (shifting the center of the saddle back in relation to the axis of the seat post) the ideal position is now reachable for almost all riders and the lock is compatible with all types of saddle skids.
