Brompton extended length seat post
The extended length Brompton seatpost is designed for the slightly taller rider (as a guide, with an inside leg 33 to 35 inches) - this seatpost gives up to 6cm extra saddle height than the standard Brompton seat pillar

PLEASE NOTE: The saddle will sit 60mm higher when the bike is in its folded position. This is due to the extra 60mm length on top of the seatpost.

Replacing the standard seatpost with this longer one is one of the easiest DIY Brompton jobs, and involves the following steps:

Remove the Pentaclip / saddle from the existing seatpost (you can leave the saddle attached to the Pentaclip) using an allen key
Release the seatpost clamp
Slide the old seatpost out (downwards) of the frame
Insert the new seatpost into (upwards) the frame
Fix the pentaclip / saddle to the new seatpost (Torque should be 15Nm for the Pentaclip)
Colour: silver
Dameter: 31.8mm

Remember! Never lubricate your Brompton seatpost
