The Ultimate USE Alien Range is one of the lightest seatpost ranges on the market, and the Alien Carbon is the lightest in the range. Intelligent design and high grade materials ensure that the Alien Carbon is tough, durable yet still lightweight. Ultimate USE’s new Alien Cyclops Clamping System uses a larger 3mm hex key single bolt central to the clamp design to make saddle adjustment faster and easier.

Used by world-class athletes and amateurs alike, the alien was created for the fastest and toughest riders on the planet.
