I recommend this product
Holds my seat up!
Some confusion over the incompatible 2012 design vs the 2017 design, but customer service was helpful & got me sorted out with minimal fuss.

Brompton Telescopic Seat Pillar Sleeve / Insert - Reamed
15 Mar 2021
Dear All,
On my last purchase, I received the wrong reference, my telescopic seat come from a 2019 Brompton. Can you confirm the correct part number for me?
Thank you in advance
This is the correct item for that seatpost; please email us a photo if you have received something different to pictured.

Is this for the main frame?

I have a tele seatpost and need to change the main frame sleeve, is this the correct one to go for?
This is for the telescopic seatpost, NOT the mainframe. SJS Cycles part number : 31199 is for the mainframe.

What is the internal diameter of this?
23 Aug 2019
Hi, struggling to find it on the internet but I?m sure I read the internal diameter of this (and that of the upper telescopic part) is 26.6mm. Is this correct please?
I have a standard one I am cutting down to convert to telescopic.
Hi there,

I have just measured this and it looks as though it is approximately 28mm.

Why can't I order from Indonesia

Hi SJS Cycles,

I am looking for the Brompton Telescopic Seat Pillar Sleeve / Insert. So far I can only find it in your shop.

However it seems I cannot place an order from my country Indonesia. Can you please explain why? Is there any way so I can make order for the item?

Thank you very much,
Unfortunately we are unable to ship Brompton parts to Indonesia in line with Brompton Selling Regulations.
