I use my telescopic seat post for pulling the Brompton. I lock the front by having the outer seatpost down, and then I pull up the inner one with the saddle in order pull the bike by the saddle. If I had done this with a normal seatpost the front would have unlocked.
Most important is that you end up with a seat post that, after pulling it out to its stop when unfolding the bike, is immediately at the correct height. The telescopic is perfect for that: adjust the telescopic part once, and only slide the main part up and down when (un)folding the bike. But if a standard or extended seat post happens to have a correct length for you, I would go for this lighter and less expensive option. Note that the pentaclip allows for some seat height adjustment too!
I have a Brompton with this telescopic post, and agree with all your points made. One I would add, is if locking the bike down outside, removing the saddle and also having the removable pedals like you have. Makes the bike nearly impossible to ride away on and steal. I will add also that I have the Tern Tour and I find that to be a better bike for TOURING than the Brompton. But in an URBAN environment, nothing beats a Brompton.
I do not have a telescoping seatpost yet. I just take the seat off and I also have removable pedals. Fits very nicely in the overhead of most planes. I have been asked several times if it is a bike & I tell them yes. I do use the Brompton bike cover. Never had any problems. I take it with me almost every time I travel.
While I'm only 6' (1.83m) tall, I got the extended seat post on my Brompton. Unfortunately it is just a little bit too short even when it's maxed out -- thanks to my long feet -- so I'll be looking into getting a telescoping one. Thanks for the advice on flying with one. Although I do have an airline-legal case designed for a Dahon, I'd like to get away from biking to/from the airport with a suitcase on my rear rack...
I almost never recommend the telescopic post to anybody whose height does not demand it, if in doubt by making certain that the pentaclip on the extended post just can't get the saddle high enough. The telescopic costs almost $100, is palpably much heavier than the single piece posts, is stiffer to support those super-tall riders (=less comfortable and more prone to slippage because more flexible posts apply less leverage to the gripper shim), and makes saddle theft a quick-release affair as well. To your points: 1. A bunch of wrenches and tools? One turn of a hex key loosens saddle enough to remove. With the money you save you can buy a nifty Brompton Toolkit so that wrench will always be handy, and still save weight. Even with an extended seatpost, once the saddle is gone the height of the post protruding out of the frame does not exceed that of the stem clamp, so the smallest compartment that the bike can fit into is no bigger than with the top of the telescopic post gone, clubbing zombies. 2. No contest that removing saddle helps with Jedi Mind Trick, but see above: 1 turn of a hex key removes saddle. If you remove top section of telescopic, you now have a larger item than just a saddle to stash elsewhere. Is that a seatpost in your pocket? 3. It's also easier to scratch your belly than your knee, but if it itches, you're not going to make a fuss about the extra reach. 4. Can't argue that. Keep up the great work. It's good to see it keep rolling from a new spot closer to fish. Do you favor telescopic rods too? :-)
Good counterpoints. Now i'm torn. I need to think ahead about what kind of seat post accessories I plan to use, as it'll all come down to that. I want to pull a Burley Travoy trailer, and the hitch goes on the seatpost. If the hitch won't fit the standard post then I'll have to get the telescopic one.
This is super helpful, thank you. I'm in the market for my first Brompton and was leaning towards the extended post before watching this video, but it sold me on the telescopic. Then I read your comment and it addressed a few concerns I'd had about the telescopic post, so now I'm back to Team Extended. One follow-on to your point #2: Not only is the removed seat "bigger" with a telescopic (since it'll have the smaller post attached to it), but I have to imagine that post will also be filthy - or at the very least, partially covered in anti-seize lube. (Or do people not apply that to Brompton seatposts?)
Path Less Pedaled hi there. In the UK you can just go on on the carradice website and order standard or large,but carradice and brompton stuff must be easier to get over here as they are a couple of the few British brands that are still manufactured here. Unfortunately that is reflected in the price!
I have a question, have you ever replaced the shim for the seat post due to wear? My seat post seems to be slipping a little, like maybe half an inch. I just have the standard seat post.
Another reason and actually why I bought it on last Brompton purchase - you can wheel the folded bike easier if you also get the rack and buy some bigger diameter roller wheels. ruclips.net/video/7aE2UkX_Afo/видео.html

@@vigorousera No lube for Brompton seatposts, ever.
you can get Carradice sqr seat post mounts for larger diameter seat posts.
You can but it’s usually a special order for shops in the US and not something many shops carry.

Fantastic tip!!! Do you still have and use your Bromptons? Looking to buy soon and was debating which post. Solved!
I have a H6L telescopic. Nice... Just a little heavier then regular extension post. But how you can fly with it?? Any way, it's more then 8 kg...
Hi, just asking whether the upper Brompton telescopic Seatpost can fit the Redshift Shockstop suspension (Dia. 27.2 mm) ?
Cool to know！Thank you for sharing！ Do you have the link to purchase the telescopic post？ 🙏
Very useful, I subscribed.

Love the green Brompton. Could you please tell me what color Brompton calls it. Thanks
British racing green
Nice info thank you...
All the 'dead air' at the end of the vid. Forgot to cut the audio track? :)
A few inches makes all the difference in the world. 👍👍
😂 did not even notice that remark.
