brompton

Crosspost from reddit. So I bought a second hand brompton and I'm excited to use it. However there are some things I noticed I need to pay attention to and was hoping you all can share your experience. First off, is it normal that the brake levers are pointing quite at a low angle? I tried to...

My son has given me his older Brompton (about 2010 I think) to fettle and sell for him. It is a British racing green S2L which seems fine - I've sorted the front wheel bearings and fixed the sticking front caliper so the bike now rides well. I've sourced a better (Brompton) saddle as his was...

I'm half-considering buying a Brompton. My current bikes are recumbents, but I also have an old F-frame Moulton and a TSR fixie. I once had a short ride on a Birdy (not sure which vintage) and it seemed very nice, although the steering seemed a bit odd on the one I tried. I'd quite like a...

My brother bought a Brompton a few years ago. It took him ages to decide on the spec, but he eventually ordered it, and it turned up at the dealer's a few weeks later. He tried to persuade me to buy one at the time, but I wasn't sure it was the bike for me. I eventually ended up buying a...

All true, in good condition. The Sach 3 speed internal hub gave up a while back.

Many people – here & on other forums – have posted on their Brompton modifications, which I have found very useful, especially the fitting of a front changer. So in case of use / interest to anyone, here is some information on my Brompton mods. The bike 1999 T5 Brompton. In yellow – at the time...

Hi - An update for all those here who helped advise - After many lock down months i've got the basics in place for a cycle round Hyde Park London....:tongue: This is an H-type superlite conversion btw.. 1. The pinstripe is protected by just applied frame protector which is why it looks a bit...

L3 or similar, something that's all there and is structurally intact (no rusted-out rear frames) but needs a good overhaul. Probably needs a rear hinge job, the gears are playing up and the wheels are shot. Anyone got anything? I just fancy doing another one up this summer.

Brompton is auctioning some bikes with special paintwork via a New York auction house. The blurb says shipping anywhere in the world is covered. Guide prices are from $1,000. Little time left on the auction, but curiously the few bikes I've checked are showing 'no bids'. A thousand bucks...

I've got a six-month-old six-speed and have noticed a slight side to side play in the rear wheel. I don't notice it while cycling only when I have the bike in a stand. Is this normal, or do I need to get it checked out? Both real axel nuts are really tight by the way so it's not that.

Hi all, My custom Brompton is sadly for sale. The build thread is over in the projects section here. A brief summary of the spec is as follows: 2005 Brompton frame, customised heavily with v-brake bosses added to improve braking over standard Brommies and the rear triangle cold set to accept a...

I am selling my Brompton as I just haven’t ridden it nearly as much as I thought I would. Money going towards my garden refurb project! https://www.ebay.co.uk/itm/Brompton-S6L-Turkish-Green-/324601028359?_trksid=p2349624.m46890.l49286...

Hi I want to replace my Brompton 2019+ folding bike crankset from the silver to black. The transmission remains the same. 1. Is changing the Brompton 2019+ crank drive exactly the same as changing other generic bicycle cranks ? 2. What is the name of the special tool which appears to be needed...

To help fund my new bike sadly I had to sell my B. I was astounded by the response I received so much so I thought I would mention it here. I thought it might be popular and that people were paying silly money for them but I have been really surprised. I thought I would stick in a buy it now...

New to Brompton. Been watching the maintenance videos after being caught out with a front wheel puncture in the middle of nowhere, and not even a pump in my bag! Front wheel was easy and quickly sorted, but watching the vid on the rear wheel removal and re-installation looks really complex and...

Hi all, we collected a new 2021 Brompton M6R Black Edition a couple of weeks ago. Was in the garage earlier and noticed something on the floor - it’s some of the paint! It’s come off the rear of the seatpost clamp - in fact it looks like some more is about to come off! Bike has been ridden 3...

Hi all does anyone know if an ergon saddle will fit on a brompton I am looking at the sfc3 I have always used a Brooks saddle on my touring bikes but just can not get a comfortable position with it on the brompton The saddle that came with the brompton there standard saddle is a thing of pure...

The bb on my pre 2013 Brompton is on its way. Is there a 3ed party BB that fits? Don’t want to change the existing chain set

Brand new black 50T chainring with black chain guard, removed from a new Brompton Black Edition bike (zero miles ridden). Fits all Brompton spider cranksets (2013 onwards). If you’re upgrading from a 44T chainring, I have the 2 extra links you’ll need to add to the chain - I can include these...

I now have an opportunity to apply for the C2W scheme and fancy a 2 speed no frills S2 model (without front block or mudguards etc. What smaller dealers do folks recommend? Warlands in Oxford seems to be one, are there others? Is it true that Bromptons are rare as hen's teeth? There's no bike...

Good evening all. The old Sachs hub on my Brommie seems to of come to the end of it's life. The 13 tooth cog also. If I got a 3 speed wheel from flebay with a SA internal hub would I need a different trigger for it, or would the present Torpedo one have the capacity to work the SA gearing ?

Hello Everybody, RE: FAG, Germany, BSA.AA, 1.37"x, 24Tpi-, RH (This is what is stamped on the plastic cover) I have a Brompton T5 and want to remove the plastic covers (see picture below) that hold the bottom bracket. I'm not sure but think the correct tool to do so would be a Park BBT-4, is...

I’ve decided to thin my collection out. So I’m selling my fully restored and updated 1995 Mk2 Brompton. It started off as a T3 but is now in M3L spec with later 2009 onwards brakes and all the bits you would expect from a later bike. I’ve lavished a small fortune on this bike, it wants for...

It looks likely that I'll have a new job from May/June this year, which is about 10 miles/15k away from here. It's a flat and generally traffic free 15k so I'm likely to cycle commute, but I would like an option for when I have to take the train on rainy or snowy days when I need to look...

Walking up to hospital to meet wife today and take her some lunch. In the window at Leisure Lakes bikes where 2 Bromptons. A S6L superlight in House red and a Tempest blue one folded. Very surprised as never had stock on website for months and months and little stock anywhere in country. Think...

Hi all, I am planning on having a bike frame built through a third party and have considered using a brompton hub or aftermarket. You will as ask why? I like the simplicity of 2 or 3 speed bikes without investing heavily on expensive setups. Unfortunately, the market likes to push toward more...

What is the optimum order to change gear ? Should I just change from 2/1 to 1/3 in one go ? or go from 2/2 to 1/2 and then 1/1 ?

Good morning / afternoon / evening readers 😊 So, I'm back with my 2019 B75 Brompton, and need to give it a lil TLC before I jump back onto it (hoping it'll be by the weekend) I neeD to buy the following - wheres the best to buy? - the sticker which protects the frame from the chain (is there a...

My neighbour has a Brompton and the bottom bracket has given up. Can someone advise what he needs to replace it with? I think I have the relevant tools, but if it looks like the one in the picture can someone advise what tool do I need for it? There only appear to be two different models...
