Alien Aluminium Rigid Seatpost
The USE Alien seat post remains market leader! 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 Alien Cyclops has a unique one-key release mechanism that makes re-adjustment as simple as a turn of the hex key.
