Brompton standard length seat post - silver

This is the standard length Brompton seatpost - made of steel

Length: 53.5cm / 21 inches

The Brompton seat post is available in 3 lengths and two colours

  • Standard length - for riders up to 33 inch inside leg (this one)
  • Extended length - for riders up to 35 inch inside leg - 6cm longer
  • Telescopic - for taller riders
  • Silver
  • Black

(In the early days of Brompton they used a titanium seatpost, then later there was also an aluminium seatpost available - these have now been discontinued - titanium due to supply issues and aluminium due to long term quality issues - the coating discoloured over time)

The Brompton seatpost has a 31.6 mm diameter through most of its length (with a flange at one end to stop it raising too far and a narrower end for the saddle to attach to)

The seatpost is installed on the Brompton from underneath (the flange at the bottom stops the seatpost being raised too far)

Remember: Never lubricate the seatpost
