Thanks for highlighting that Brompton toolkit tyre lever/wrench cameo in 4:03! I had forgotten it was part of the kit and was despairing about a slipping seat post today. Quarter-turn advice did the trick.

Sitting at my desk during lunch break, next thing you know I've got my toolkit out, cleaner, paper towel, click-slide-tweak and I'm ready to go! I have my Pentaclip upside down to get an extra 2cm height and it's like I've got stronger legs, so slipping down again was frustrating. Thanks for the easy to follow tips.

Thankyou, l’ve often wondered about the seat post. I clean my bike regularly after use and before winter storage, it gets a super clean and oil. So in the spring it rides like a dream. Your video answers many questions l previously had about seat posts. I love my Brompton which l’ve rode over 5 years, a sheer joy. Best wishes to you and your viewers. ☺️👌🌈

I just tighten the screw and hope that works. I'll find out on my next ride, because my seat has been slipping since I purchased it, so it's definitely not due to being dirty. Thanks for the tutorial👍

One solution is carbon paste. I now have a carbon seat post installed so it's essential but I had metal ones before and they were often prone to slippage. Park Tool carbon paste makes all seat posts rock solid in your Brompton. Disclaimer..I rarely fold my bike up completely, usually having the seat post up at all times. For those doing daily folds this might not work so well.

The quick release lever mechanism also needs cleaning and lubrication now and then. If the excenter axle gets dirty it will develop scars and wear out. The whole assembly can be disassembled if you are a little handy, using a mandrel and a hex wrench to drive the axle out of the plastic handle. I rescued mine and now it works perfectly. More details on request.

@@stephanmaier5634 First remove the whole quick release assembly from the bike frame. Take careful notice how the parts are located, in particular the spring coil. It may help to take a close up photo for later reference before proceeding. I removed the excenter axle from the plastic lever by holding the side with the hex shape on top of a 13 mm hex socket, and then pushed it out using a 4.5 mm drill bit and a mallet. This is just one way of doing it, but I think it is a good idea to support the plastic material carefully so it doesn't break. The excenter and the bolt should cleaned and greased with a high quality sticky grease that stays in place. The working of the lever will be a magnitude smoother after this service. On the other hand, a new lever is quite cheep and if the parts are too worn it would be a better idea to replace it, and keep the old parts as spares.

I’ve just got a brand new Brompton and struggling with a slipping seatpost. I’ve cleaned (even though it was clean anyway) and followed instructions to tighten up so it’s a bit firmer but it’s still slipping and I’m hesitant to tighten anymore for fear of going too far. Any tips? It’s really frustrating and dropping a good inch over a mile of riding.

finally they are addressing the issue, my first brompton had same issue and couldn't be fixed when I sent my bike to brompton junction in covent garden in london. I gave up with customer service I ended up selling the bike. I then purchased second one with same issues. I took it to same shop for maintenance, they changed frame sleeve but problem didn't go away. Long story short I have returned the bike for full refund which I am still waiting. Now I am going back to normal road bikes. I think these bikes are no longer made for quality rather for quantity. I doubt that I will be buying brompton in the near future. Update: I’ve got my full refund now. Well, I ended up buying the third bike so far so good no slipping issues.

After about some years with this issue I found out that, by grinding the bottom of the seat post with a coarse sandpaper, thus augmenting the grip where it finds the sleeve once the latch is closed, works superbly. It is very simple to do that!

There is something called 'carbon assembler paste'. For non carbon bikes there is something else, like official grease for your seatpost. Counterintuitively, the grease is supposed to help your seatpost grip and stay in place by 30 percent.

@@100toeface I don't think that could have helped since my two unlucky bikes were made poorly because frame was made a bit wider for seat post to clamp firmly. I've given brompton third attempt. My third brompton seems fine no more slipping issues and I don't have to over tightening the nut.

could you just drill a hole through the seat post for a pin?
@BrookValentine
Жыл бұрын
I've often thought about this... but not through the seat post, as I'd be worried about it bending at the hole. Rather, I've thought about in the frame, halfway between crank and top tube, so the pin would go UNDER the end of the seat post. The I thought "this only works for those who extend their seat post fully". Maybe a mod I can do... if I'm brave enough! (but cleaning and tweaking is working so far)

I weight around 205 pounds facing seatpost slipping down problem. It slides down like 1 centimeter in few miles and few inches in like 15 miles. Is it normal for a heavy rider like me?? my seatpost and the internal thing inside the frame is clean. I also tighten up the clamp. Seriously, is it about my weight? Is there anyone facing a seatpost slipping? How do you solve it? Really do appreciate it in advance.

Mine's electric, my second Brompton. Bike tracks around my home have many bumps, which don't help with slipping. My thought is that the factory torque is great - for an unridden bike, and that after a run in period we should all readjust the nut. Pulled my seat post out during a lunch break after watching this and was surprised at the gunk on the post. Metho and paper towel, tweak nut, rock solid again... for now.
