Carbon Seat Post Range

Make additional weight savings with a carbon seat post upgrade from Sigma Sports. Beyond this advantage, carbon also helps to absorb vibrations from the road lending itself to a more comfortable ride. 

With premium seat post brands such as Zipp, Specialized, Cannondale and ENVE available, it is possible to replace your old seat post with an upgraded lighweight, carbon alternative. If you have any doubts about which seat post might be best, check out our buyers guide.
