USE Alien Carbon Seatpost 400mm x 27.2mm

The Alien Seatpost range is one of the lightest on the market and the Alien Carbon is the lightest in the range. Intelligent design and high grade materials ensure that the weight is as low as possible while maintaining durability and long lifespan. 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 was developed for the fastest, toughest riders on the planet. It was selected to adapt Laurne Jalabert’s bike in the Tour de France to assist him in winning the King of the Mountains jersey.

10mm layback.

PLEASE NOTE - Clamp fitted is for standard 7 x 7mm round rails. Clamps to fit different sized rails are available on our accessories page but NOT for 9 x 7mm rails.
