The Pro Atherton DH Seatpost - 250mm was developed in conjunction with World Championship-winning and World Cup race winners Gee, Rachel and Dan Atherton and boasts an In-line design and laser etched logo graphics. Designed to perform in the most extreme environments, this solid yet lightweight downhill seatpost uses a 3D forged shaft and CNC machined head constructed from 7050 alloy. The 7050 alloy is made by a two-stage heat treatment process resulting in a light but strong component with excellent resistance to stress-corrosion and cracking.
