Alien Aluminium


The Alien Seatpost range is one of the lightest on the market and the Alien Aluminium is the most affordable. 7000 series aluminium keeps the weight down with a choice of colours to coordinate your bike. The Alien clamping system 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. It has been used by World-class athletes, at World Cups and by amateurs alike. It was developed for the fastest, toughest riders on the planet.

*Supplied with standard 7x7mm clamp. Other size clamps to fit oval carbon rails are available. Please see the saddle manufacturers measurement, if the rails are wrapped please check the measurements are still valid.
