ConsCost (but cheaper than some other options)
ProsLightweight, good quality
Seems like a well-made product and appears as advertised. Replaces the original standard length seatpost while shaving a couple of hundred grams off the overall weight of the bike. The mechanism used to attach the saddle is a little more fiddly than the Pentaclip, but is still relatively easy to attach the saddle and adjust the position. Some claim that titanium seatposts offer a more flexible ride/increased comfort. Personally I can't tell the difference in this respect.

Lovely. I merged it with USE Evo91 Clamp Kit to provide better support. However this might be overengineering (I am German...).
Questions & Answers (11)
how does the length of this compare with the extended and the telescopic seat post?
18 Jul 2019
The two lengths sit in line with the standard and extended from Brompton.

Why is this seatpost 520mm long when a Brompton seatpost is 530mm long?
12 Jul 2019
Because this does not use the pentaclip system so the set up is altered, the set length is about the same though.

Can I use this with a Brooks B17 saddle?
22 Jun 2019
Yes, this would be fine!

Hi, Is that seat post provided with a bung to avoid direct contact with the ground ? Thanks
15 Jun 2019
No bung is provided, but the bottom is flared so you can fit the OE Brompton one.

Thanks - 17/06/19
Is there anything extra needed when ordering this, like bushings etc. ?
16 Feb 2019
This comes ready to fit and use, with all the parts required.

Is this seatpost made in the UK?
25 Aug 2018
The seat post is not made in the UK, Jtek are a UK based company though.

Is this suitable for a saddle with carbon rails?
04 Jul 2018
It's hard to see how narrow the clamps are - do you think this would be suitable for a saddle with carbon rails?
We do not recommend this clamp style with carbon rails.

Titanium grade?
05 Nov 2017
Is this grade 5 or 9?

These seat posts are made from 3Al-2.5V seamless titanium tubing.

30 Jul 2017
Is this seat post flexi (in a good way) like most Ti ones are? or stiff like Alu/Steel? Thanks!
Hi, Yes it is flexible like other Titanium posts. Thanks
