Brompton owners

Oh cool, what did you think? Haven’t seen anything in the media about it which is surprising

I think it's one of those well-known secrets? People in the industry have been talking about it for a while.

It's nice. Would I be tempted? Yes.

Both were with non Brompton internal geared hubs hence on the heavier side, love the disc brakes, didn't mind the additional weight and it was super comfy.

Proper adventure bike? No.

Bike I could have a weekend to myself going anywhere I'll like? Yes.

As much as I would have loved to sneaked a few photos, I didn't, you'll just have to take my words for it.

Nice! Randomly my friend saw it unbranded outside a cafe in summer 2022, wondered why they still haven’t released it yet

Thank you, with the 18" kinetics i was thinking the fold wouldn't be much bigger. for me it's the day to day bike, i don't have a house with a space to store a bike outside or space for more than my roadie inside so a the brompton is perfect but i'd go larger (with the same ease of fold) if it made life over what passes for a road surface in the UK safer/more comfy. I'm. not a daily commuter so less fussed about the weight. The kinetics with disc and hub looks very utilitarian. Interesting to see that g-line concept

I think you should do it. Personally if I were to do it again I'd get the version with more clearance rather than larger diameter wheels.

Gearing wise, I went with Sturmey 3 speed disc hub, works perfectly, I use all 3 gears.

I will defo consider the G-line. The Brompton is incredibly versatile as we know. I still sometimes commute down or crossing the marches in East London, which is often quicker, quieter and the more scenic choice. Yeah I know Bromptons get mugged and the canal paths there are notorious, but I'd still like it to be that bit more more capable to deal with rougher terrain.

New Brompton has arrived which is very exciting. Now to start messing around with upgrading it. Its a 6 speed with a 50t chainring. I live in a hilly area, will take the bike touring so was planning to reduce the front chainring. I have some black 165mm spa cranks with a 44 or 40t chainring I am planning to test fit to see how they affect chain line and fold. I was initially going to go 44 but the 40/gives me a nice 65" ish gear . I don't mind being fairly spinny and mostly ride low geared single speeds.

Has anyone else changed gear ratios, got any thoughts on this?

Also @hoke I got a t-bag from eBay cheap cheers!

Sort've. I did my own, ghetto, light-as-the-carbon-one chainset hack. Ended up with an FSA Megaevo BB (the one Brompton uses on the carbon fibre chainset), FSA/Cannondale Si Cranks with the 119mm spindle swapped in, and a 50t SRAM CX1 chainring for better chain retention.

I then changed to the 12/16 sprocket combo on the rear. This gave me an ever so slightly higher top end gear than I had before, and a lower bottom gear (54t chainring with the 13/16 sprockets.

Kudos, any picture of the crankset you planning to put on the bike?

Take a look at Ben’s Instagram page. There’s some good photos he’s posted showing the size differences folded up between the two. It sounds like though that it’s mostly for east of storage in which case a slightly larger footprint sounds fine. I was just cautious as when taking it on the train the 16” fits well into the end of carriage luggage bays and wasn’t sure how the 18” would fit here

Care to share how cheap?

Got a good condition T-Bag for £60

The steerer and rear triangle on my frame is black and all the components are silver. I'm going to slowly switch components to black where poss. I have a pair of these

In 165mm black with a nice bike punx chainring. I've got a 44t and a 40t. I think I'll go straight to the 40t (which I think needs 96 chain links)
I'll do a test fit and see how it compares to stock.

Here's a bad pic of the bike. It was on sale so not my first choice of colour but it's fine.
Got black bars, did saddle, new block and chain set to fit this weekend. I also need to figure out how the gears adjust as the bike came with the rear hub cable disconnected.

Cheers, don’t know if this is any different to the eBay ones but might go for it too as I’m needing a 165 on my Brompton due to my short as legs and rather get shorter cranks than spacers in the seatpost.

In terms of quality I have been running these cranks on all my bikes now for the last few years no probs. Lots of options. In terms of brompton fit I will find out this weekend if bb needs changing to work.

Imo the key elements that make Bromptons hard to beat are: 1. Speed/Ease of fold, 2. Folded footprint, and the big one... 3. Wheelability when folded.

What I'm hearing from your post is that none of those are really relevant to your use and something that's quick to fold with bigger wheels like the Tern Link would be more suitable.

The Brompton BB is a JIS square taper with a 119mm spindle length. The width is important to clear the folded form. A quick glance at your link, and it looks like you'll be okay?

Nice score!

Good tip, he should put those on the main site. The 20" MTB version is very compact.

Got a 42t front chainring on mine, with the six speed ratio i think it's the best compromise i could have asked for.

Nice. All black looks good. I have a 41t tooth chainring I'll try.
This says 44t chainring requires a 98 link chain and 39t requires 96links:

So you know what chain length you are running with 42t?

Nice.. I think that frame colour goes well with silver. Probably less parts and less expensive route than going all/mostly black.
