A tough construction using high-quality carbon fibre, the USE Alien Carbon Seatpost weighs just 140 grams and makes every effort to pare back the design of this essential component.

With a single bolt clamp design offering a minimal and fuss-free mounting to 7x7mm rails, this seatpost is setback at 10mm for greater comfort and vibration damping on the road.

USE Alien Carbon Seatpost

Strong and light, the USE Alien Carbon Seatpost is an elite option for weight-conscious riders looking to shave critical grams from their setup. Made from high-quality carbon fibre and weighing a claimed 140 grams in a 300mm edition, this seatpost is available in 27.2mm or 31.6mm diameters.

A 10mm setback offering greater comfort and vertical compliance, the Alien Carbon retains its lateral stiffness for peak performance rides. Implementing a single bolt clamp design for simple and ultra-lightweight fastening, a net weight of 140 grams assures you of fantastic climbing performance and a substantial reduction in weight over more conventional designs.
