Brompton black extended length seat post - steel

(Note: Picture shows telescopic - for colour purposes only)

This extended length seat post is 60mm longer than the standard length

Brompton BLACK edition extended length seatpost - as supplied on the Brompton BLACK limited edition range and available to the after-market since 2016 and a standard colour since 2022

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 post

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

Compatibility:

The Brompton seat post is one of the only components compatible across all models / ranges and is compatible with the following:

  • B75 / A Line (came as standard with a silver extended length seat post)
  • C Line
  • G Line (used this black extended length seat post as standard on the medium size bike)
  • P Line
  • T Line (though as standard it came with a lighter carbon / steel seat post)

Installation:

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: Black
Dameter: 31.8mm  

Remember! Never lubricate your Brompton seat post

Not compact

Be aware that the extended seatpost makes you folded bike less compact - the extra 60mm means the saddle sits 60mm higher in the folded position, which is the difference between it siting between seats on a train and it not...

If you value the compactness of the brompton (And why have one otherwise), then go with the (More expensive) telescopic post, this adds closer to 30mm, but allows the seat to be easily removed if you do end up wanting to hide the bike in a tight spot.

Brilliant Bikes were great with a swapover, so top marks for them
