Living in Marseille, I was lacking more granny speeds.
Especially since I installed a 56t chainring. So I converted my 4spds TLine into a 12 speeds.

Now I can climb the one tallest hill in Marseille I live atop of without lifting my butt! And go real fast when I’m in a pinch.

The bike is heavier but it’s worth it for me.

Thanks for the update Shu. Really glad the T Line's going strong. How I wish mine was squeak free ;) Hope you and the family have a great summer.

I agree with all the statements you've made. For me 4 gears is perfect for NYC. I had the 6 Speed Superlight and I found I only used mainly 2 gears so for me the 4 Speed is perfect. My frame has some scratches here and there, made some mods, but i think that if something happened to this bike I would buy another without question. For me it was a big upgrade from the 6 Speed Superlight. They feel like 2 completely different bikes. The Superlight plods along but the T just wants to go!

Love this bike. I'm coming up to 2 years on my T-Line too and it's holding up great. Couple of observations from discussions with other T-Line owners. I've never had problems with gears slipping myself but others who've gone with after market tensioners or derailleurs like you have faced issues. Creaking is generally a problem for heavier riders and yes, tightening and greasing eliminates plus do remember to apply grease on the inner surface of the hinge clamps. I've changed to a 56T chainring and 11, 13, 17, 21 (11, 13 stock) cogs and the resulting wider gear ratios on both ends has been the best upgrade by far. I'm still running the stock tensioner & derailleur which is almost bomb-proof.

Everytime i watch one of your Brompton videos i also want to have a t-line :)
I also like your honest and simple made video format and your cruising videos.
Thank you and greetings from Germany!

Thanks for the video, I hope you and family are doing well. Hello from Atlanta. By the way I still love my T Brompton

The Praxis BB and cranks are super sweet. I have em on my B75.

Have had my T line one year love it. Stays in my trunk I still laugh every time I lift it out the car as it is so light.

Went out to find a shop that stocked Brompton's in Sunningdale, UK and found that it had a T line in stock, so now I am a proud new owner of this and a Superlight that I keep in Spain. Also, I have three Moultons. No such thing as too many bikes.

I have a superlight in flame lacquer, and had a TSR 9 by moulton. I sold my TSR 9 when the t-line 12-speed came out and bought the TLine 12s.. It was a hefty purchase, but it is an absolutely gorgeous piece of engineering and I'm glad I bought it!

[fishbert]

That chainring looks absolutely massive

[SouthSideChiTown]

About that plug for pedal storage that keeps coming undone, maybe you could insert a tiny neodymium magnet inside it that would actively hold it in while you're riding.

Shu in da' hoouussse! Was looking forward to this update to see how the T-Line was aging and, like you, it's aging beautifully like a fine wine. It looks practically brand-new and the few scratches and patina it does have shows how much the bike has been loved. The T-Line is terrific and your channel has been instrumental into me getting a T-Line also. Can't wait to see how the rest of the bike is holding up. It's crazy that your carbon chainring looks to be doing great too. Since your build, are there any other chainrings or parts that you would swap out for the parts you have now? I like your idea of the 12-speed but I love the single chainring more. Would perhaps get a couple of more cogs in the back for higher gears or, perhaps, get a Rohloff speedhub. I'm not convinced either way. Your 4-speed is a minimalist masterpiece... alright alright.

BFT..I forgot the handlebar length after cut. I may want to do it, could you tell me 🥸

[seductive_Octopus]

Is it already 2 years. 😮
Man, I feel old now.

[csadams]

Curious your thoughts on Hummingbird folding bike. Has a belt drive option which is nice, doesn't fold as compact tho. Carbon instead of Ti.

[finncarlbomholtsrensen]

As an owner of a now much former than 2019 Superlight, now below 9 kilo, with mudguards (( What's left of the original bike) I'm a Rainy Dane), I would be scared of mud and water coming down on the crank and ball bearings in front, from the strange holes. I like the new and replaceable hinges, but I don't use it daily, as now 76, so it isn't a problem for me. And I have 6 gears, of which some are so low that I didn't know for what use I had them, till I met a serpentine road and had to walk on top! Finn. Denmark

thanks for the video....when you do next T-Line video for parts can you please add the chainring too....just needed to know if the chainring is the spider kind...its a five bolts so you can change the chainring with any kind of road bike chainring size....i got a 75T on my C-Line...on earlier videos on T-Line i think they have a different kind of chainring

[richmck]

Man, love your eyeglasses. And the long carbon fibre seat post. Where are they from?
And you must have been one of the first people to have a T Line, as I live in London and it was hard to get this version then.
In the end, after trying it at a trade fair, I went for the P Line in speckled Black with 4 speeds due to the price. Love it!

I also noticed a crackling sound from the front fork upwards as well when i go over bumpy cobbled streets like you have in The Big Apple. I am in Europe and Brompton say we should all avoid these kinds of streets!

Abraço, muito cara essa linha t nova
