The USE Alien seat post is ultimate lightweight seat post designed for the performance rider. Utilizes the latest aluminum and manufacturing techniques. The Alien has continually evolved with the latest being the Alien Cyclops. Using a larger (3mm hex key) single bolt central to the clamp design, the Alien Cyclops makes adjustment easier and faster. The new Cyclops design is stronger than ever and is even 5g lighter. The Alien Cyclops has a unique one-key release mechanism that makes re-adjustment as simple as a turn of the hex key.
