Brompton Extended Seatpost
The Brompton Extended Seatpost raises the saddle an additional 60mm, creating a slightly larger folded package, but a much more comfortable ride for our taller friends. Ideal for riders with an inside leg measurement between 33" and 35", it offers additional saddle adjustment without affecting the bike’s fold or compact size.
Crafted from high-quality steel and finished to match Brompton’s signature look, this seatpost is a direct fit for all models. Measuring 23.2" (590 mm) in length and 1.25" (31.8 mm) in diameter, it gives taller riders a more comfortable riding position and the same reliable performance expected from every Brompton component.
