Color & Lenght

The stock seatpost works. But it's heavy, it rusts, and it's not exactly exciting.

This titanium seatpost is a direct replacement — same fit, same function, but made from grade 9 titanium alloy. It's lighter, stronger, and won't corrode. And unlike most titanium upgrades, it comes in five finishes including rainbow and gold, so it can be as subtle or as eye-catching as you like.

How it works

Direct swap for your stock Brompton seatpost. Remove the old one, slide this in, set your saddle height, tighten the clamp. The diameter is 31.8mm — the standard size for Brompton. Three lengths available to suit different rider heights: 535mm, 550mm, and 580mm.

Key features

  • Grade 9 titanium alloy — stronger than steel, lighter than aluminium, and completely corrosion-resistant
  • Five finishes — natural, matte black, sandblasting grey, gold, and rainbow. All applied using anodising or surface treatment, not paint
  • Three lengths — 535mm, 550mm, and 580mm to suit your saddle height preference
  • 31.8mm diameter — direct fit for all standard Brompton models
  • Lightweight — noticeably lighter than the stock steel post

Which length do I need?

Most riders use 550mm or 580mm. If you're taller or ride with your saddle high, go for 580mm. If you're unsure, send us a message with your height and we'll help you pick the right one.
