TPW Titanium Seatpost – for Brompton
The TPW Titanium Seatpost is a precision-crafted upgrade for Brompton riders who want to reduce weight and enhance ride comfort. Made from high-quality Ti-3AL-2.5V titanium and CNC-machined for accuracy, it replaces the standard steel seat pillar while saving an impressive 110 g. The result is a smoother ride, reduced overall bike weight, and a cleaner aesthetic.
Available in both Standard (550 mm) and Extended (600 mm) lengths, this seatpost offers the same fit and function as Brompton’s originals but with the strength, flexibility, and vibration-damping qualities of titanium. It’s a direct-fit replacement compatible with Brompton’s Pentaclip saddle clamp and folding system.
