    Confirmed. Water does collect at the BB area. I actually saw a vid where someone was taking out the BB and water poured out 😅
    The original design is better and cleaner for aero. I think they shouldn’t have worry about those few grams making water an issue and having a slower bike that creates “dirty air”

      IMO having all titanium will sacrifice ride quality. Titans such a harsh ride, that having carbon fork and seatpost is way more comfortable.
      I bought a competitor all titanium bike and endedup changing the seat post for that reason. It was my first titanium bike and I just didn’t realize that issue. Big regret.
      Anyway the Brompton is a great bike, but 16” wheels don’t work for me. It they ever make a 20” wheel, well then we’re talking.

    Brompton wrote back to me regarding the water in the top frame. I'm sure they are aware this letter will go public as I message them coming from this channel. In short there is no need to worry. If there are any issues they will sort it out. The bottom bracket is sealed internally. I would suggest T-Line owners to stuff a plastic bag in the top tube during a downpour anyway:
    Hello [DrJames]
    Thank you for contacting us here, at the Brompton factory and for your interest in our brand new T Line model.
    To the best of my knowledge, corrosion can occur when metal is in contact with water(from the road, would hasten the process). Your concern that corrodible materials could lead to rapid degradation, and the effect that may have on the structural integrity of the bike is understandable.
    In raising this with our design team, I have been advised that the T Line's mainframe has been tested in our test shop, for thousands of hours of continuous exposure to damp road conditions. The bicycle with this same characteristics has been ridden over many miles of test rides, for the same reasons. We do believe that the bikes frame should not present a usage difficulty arising from water corrosion, regardless of the new design (hole between mainframe and front frame).
    If however, owners may encounter component issues, when they are putting their T line through its paces, we shall certainly act to remedy any such issues for owners. For how the bike is conceived, I confirm there is no possibility for water to penetrate within the mainframe and to reach the bottom bracket, as it is sealed internally.
    Please note that you will get 3 free services for your T Line, which will be performed at the Junction Store of collection. meaning, if there is any issue with the bike, our mechanics will be more than happy to assist the end-users fully...
    ...I hope this helps to clarify. Should you have any further questions, please don’t hesitate to get in touch.
    Kind Regards,
    Marco

    The T-Line shows clearly, that the original Brompton is really hard to optimize.
    One thing that can be optimized is the poor drive train of all Bromptons: It should have an internal geared hub of high quality that fit in the small 112 mm spacing of the rear triangel. That could be a customized Shimano 11 Gear hub or (just a dream) a customized Rohloff.
    Is a Belt better than a Chain? - I think yes, but I do not know if it is folding as good as a Chain ...
    The left Pedal: The original folding pedal still is the best compromise, even though it has the problem, that ist must be unfolded when the bike is unfolded because the pedal cannot pass the rear triangel. I have used some version of quick release pedals and it is very inconvenient (and "dirty", because the mechanism needs some lubrication) to stow the pedal especially in everyday situations (the video could not have shown it any better).
    Also a "no go" for everyday usage is the lack of lighting. SON offers the perfect dynamo hub for the Brompton and the cabling should be as integral as possible. LED-front and rear light weigh just few grams.
    There is no need for a rear carrier, and it is really good, that Brompton included the front carrier block even to the T-Line.
    I don't like the original brakes, even though they got better over time. I would prefer V-Brakes or hydraulic Brakes, especially on the rear wheel.
    But again: I tried a lot things myself (Rohloff, Hydraulic Disc Brakes, Shimano Nexus 8 with Rollerbrake, Quick release Pedals, other Folding Pedals) and I know exactly that it is really hard to optimize the original Brompton (for everyday usage).
    The only optimization I can recommend without any consideration ist the SON XS for Brompton dynamo hub in combination with the FLAT S PLUS or 2C PLUS (rear) and LUMOTEC EYC or LUMOTEC MYC from Busch + Müller. I use a soft microphone cable for the rear light.

      I find the Shimano hubs are much less forgiving than the 3 speed SA ones. The latter are very robust. If the shifter index on Shimano hubs drifts, they get ruined. The internals seem a bit on the weak side.

    I have bought a black Titanium seat post for my LightweightH6LXBrompton, with a lightweight AceOffix saddle mount on top, for the mounting and angle of the saddle. I have an original, titanium fork and back-frame as standard and I look for a titanium stem post, as I have changed every loose part I could find, to titanium. But I still have 6 gears for use in a hilly area!

    Price tag is really challenging for me. I’m wondering where Brompton is heading as a companies. Feeling diversification of lines, integration of major third-party component, are a bit hasty. Also pretending to democratize bike as a mean of transport with bikes trending between 3 and 6K is a bit provoking

    Excellent video from clearly someone who cares. Thank you.
    I did a test ride myself and it does what it sets out to do, I think. One purpose: it’s light. Crazy light. I felt no difference with the test ride on the short journey I did. Expect that the handle bars are noticeably wider. But no biggy. I also loved the new seat. Much smaller (lighter) but very comfortable. I know it’s on the P Line.
    Like you. Interested to know about the rain. Probably doesn’t matter. Even if it’s heavy rain you’d probably stop at some point to unfold it drain anything out. Which won’t be much by the looks of it. Tbc though.
    Couple of minor worries. The beta testing for early buyers. I hope it’s safe. They should definitely make clear that buyers are beta testers. And if there are any major faults. These need to made and the buyer compensated. Issue with this stance is that I know all products are beta products. But for Brompton representative to say that is very worrying. Even deficit full. Small red flag.
    Repairs. Can parts be bought? These are new parts so not yet. That could be very expensive.
    Plus the inner tubes. Can other tubes be used. £26+ per puncture is steep. May even be an idea to swap for Racer tyres and tubes after the first puncture as these treadless tyres are prone to punctures in London from experience.
    But as said. It’s a crazy light Brompton. That’s been the talk of the town for years. And they’ve delivered. If it’s safe and rides the same as any Brompton. Job done. If it’s faster or smoother that’s a bonus to me. I imagine it will be though (too early to say from my early test).
    Thanks again.

    I question all the range options which started to materialise in around 2006. I don't think they do anything for user experience. While Will Butler Adams did transform the company, the emphasis on marketing and vanity over the original 'form follows function' ethic I'm not a fan of. It's a HiFi bicycle now and mostly over priced.
    Maybe the company would have not survived without this fundamental shift.
    I would like to see their engineers put energy into developing an affordable folder; more than the recent lower grade basic Brompton with no mudguards/folding pedal which they marketed a couple of years ago. Something different, something sub 600GBP, 12Kg max and folding to a 35cm cube. Less emphasis on obsessive weight minimisation, more on affordability. Maybe not even a bicycle, maybe a decent folding electric scooter.

    • @DrJamesT

    Thanks for making this video. I certainly have been looking forward to it, since watching your last video.
    I have a lot of mixed feelings tbh.
    First off, it's very disappointing that at this price point the bike is being released to the public for further 'BETA' testing in return for just 3 free servicing opportunities. My understanding was that the bike had been developed and tested for a whole year. Certainly this is no pharma company in R&D in a phase IV drug trial. I have not heard of such a process with any other big bike brands like Specialized, Trek , canondale etc.
    If this truly is the official stance, and one must assume so given that a Brompton Junction T Line "Expert" is saying so then it must be true. Brompton should have been more forthcoming and clear that this is a BETA version and it should NOT have been sold, rather given to select customers to provide feedback. If this isn't true then they really need to communicate with their staff.
    Rolling my eyes when the expert says 'they' haven't told us, I forgot to ask 'them'...appreciate his honesty but the disconnect is ridiculous. Can you imagine walking into the apple store and hearing that.
    Am I being to harsh on the expert? maybe, but its not personal, I am sure he's trying his best given the position "they" have put him in.
    How could 'they' Brompton HQ/engineers not have considered water drainage.
    ok that's my 50 cents on that for now.

      When the 1st iphone came out it had lots of issues including phone reception. All those people who got the 1st iphone are really testers for the next version. They paid for the R&D for the next version. Companies need the cash to invest. Brompton is no longer headed by an engineer but a business person. They invested resources in retail stores, marketing and 23 T line support videos on TH-cam. All these fancy videos and product launches require timing with third party providers. I just saw the brompton market lead on LinkedIn thanking all the companies that made the retail display units for the T line. Because the supply chain is broken the T line was delayed. But since the launch must go on. I suspect it was premature. They don’t even have enough bikes to fulfill the demand. It’s possible this was done on purpose too mimicking Tesla Model 3 launch. People waited a year to get one and they put a $3k deposit for something that didn’t exist. The crossbar hole is a concern. I hope I can get the attention of one their engineers to comment.

    There are so many reasons to like this bike and to appreciate the work that has gone into developing it, but for me it looks like a cheap aluminium bike you could buy online anywhere due to the thick tubing. I've always loved steel because you can manufacture a bike with the most elegant, slender tubing. This new Brompton, whilst undeniably impressive, would offend my eye every time I look at it, sorry! Before I get shot down, can I just remind everyone that it is a good thing we all have different likes and preferences and my love for the steel Brompton does mean that I'm not going to be taking a Ti Brompton out of the market thereby denying a Ti-lover his dream bike :)

    • @DrJamesT
      @DrJamesT  2 ปีที่แล้ว +1

      Brompton has rear suspension using a rubber block. T-line has a stiffer suspension block than the C line. It's the same block as the P-Line.

    Does the new seat clamp/suspension block design actually remove the play on that T line which quite obvious on the previous model? Like the new rear triangle design and the derailleur set up this time to be honest apart from it looks very low on the ground. The stem clamp is quite good but saw that already few years back when someone converted the Brompton stem upper part to accept 31.8 bars. Some parts is like Brompton catching up with 3rd party vendors and Brompton modders😀….more external gears, hinge clamp, removable pedals, Tubolito😀…..again would love to see a water bottle mount behind the stem😀
    Forgot to ask also if you tried to hold both brakes and rock the bike back and forth if any flexing by the stem/fork area?
    I just wish the first batch people will actually get a much better welding finish than that demo.🙃

    • @DrJamesT
      @DrJamesT  2 ปีที่แล้ว +1

      I rode this through regular london traffic. I experimented with the front, back, and both brakes after reaching 5-10mph and there is no obvious flexing in the stem or fork. Brompton is not a risk heavy company. It took 20 years from idea to launch for the titanium frame. 10 years to add an electric motor.

    Does water still leak into the front brake cable at the 'gatherer'? The outer was in 2 parts and the cable rusted. Why not use a noodle to ease the 120° cable bend?

      The cables bend to 30 degrees when folded. What's a noodle and how will that offer relief? I've seen on Brompton Hacks someone installed a Duomatic hub - it's a 2 speed hub and brake in one, controlled completely by the pedals to create a wireless system.

    Thanks for the questions and thoughts. Lots to chew on, some which makes sense from a product perspective, some which might make more sense well after time/rides.
    Question(s) to you @DrJames:
    - titanium doesn’t (usually) have the quality of rusting or warping due to water damage; granted, some cities have funny water. What’s the concern about the water damage?
    - the handlebar seems to be held onto the bar now by half a usual stem fixture (the front part of the stem of many normal bikes); could you confirm? If so, this would be a really neat area for accessory innovations *and* something I could see showing in a redesign to other Brompton models in the near future
    - does the Brompton toolkit fit inside the frame (if so this would be a pricey but suitable water-collection solution)?
    - you mention the acceleration and ride feel; would you say it leans more sporty (P-line) or more cruising (normal Brommie)?
    - feels there’s actually a tick more speed in this model besides adding the 54t up front… I wonder what Brompton might be plotting for touring/explore iterations where a lower or wider gear range amongst 4spds could be played with
    Thanks again… very helpful video 🙏🏽

    • @DrJamesT
      @DrJamesT  2 ปีที่แล้ว +1

      -There appears to be a hole in the top tube that leads water into the diagonal bar between the top tube and stem. This bar could 1) fill up with water 2) lead water into the bottom bracket see th-cam.com/video/k5VCsB_0xl4/w-d-xo.html
      -I'm not sure what you mean by "half a usual stem fixture". th-cam.com/video/k5VCsB_0xl4/w-d-xo.html shows a plate bolting down the handle bar onto the stem. For sure accessories can be made on top of this. There are accessories made for the current brompton to hold smart phones.
      -The circumference of the Ti top tube is 17cm vs 14cm of the steel eg it's got a larger diameter so the tool kit will fit in there but it will slide to the back. You can certain create a plug to block it ie like useful rain cover rolled up
      -sporty and cruise depends on how much you lean down when riding. You can choose the Mid (cruise) or Low (sport) bar for the T-line
      -Brompton doesn't have to plot anything - go to brompton hacks on facebook and you'll find people are already customising the bike to their adapt to their needs. You can easily change the size of the cogs on all their bikes for $3-4 USD per cog.

    • @ARJWright
      @ARJWright 2 ปีที่แล้ว

      - ah, water into the bottom bracket could be nasty. Yikes
      - top of the stem looks like the front of a regular bike’s stem
      - interesting on size of tube; thanks for clarifying that part
      - the rider’s lean determining the feel; I wonder 🤔
      - not on FB, but aware of the usual hacks; thinking more along the lines of what Brompton has been doing w/thematic products. The shift to 4spd feels like it points to other branches that only hacks explored, and some hacks couldn’t explore fully (am in design, it’s just a lens that happens around every product)
      Thanks for your responses once again; definitely need to get to Brompton Junction NYC when the weather dries out, and see about getting a test ride

    I was initially very excited about this new model, but then began to notice things that I didn't like, such as the use of carbon fibre forks, handlebar and seat post, and those ugly holes in the hinges.
    I also didn't like the cassette gear.
    However, the major dislike was that it wasn't an Andrew Ritchie Brompton!
    What drew me to the Brompton was its design and engineering excellence, and I love how it looks when folded, perfectly engineered by its passionate designer.
    This new model changes virtually everything, not even using the existing titanium forks and rear triangle!
    Simply put, its not an Andrew Ritchie Brompton...

    Hi, excellent review. I have two questions:
    1. Do you think the new Swytch ebike conversion kit could be installed on this T Line Brompton? If no why?
    2. You mentioned that you can feel every crack on the ground which got me worried about my back and wrists. Do you think that by changing the rear suspension and the air pressure you could get it to a decent enough state to minimize impact? What other mods would you recommend to make the ride as comfortable as possible ?
    Thanks!

      You might have missed the answer to question 1 in the video, the fork is carbon. It's not designed to handle force from motors. 2) change to a softer suspension or change the tires, or get a seat post with suspension.

    As I have just bought a "hollow" titanium bolt to hold the stem post, on my Lightweight, it do make sense. But I still like my double, easy wheels on my mudguards to be able to roll. I have also bought some "carbon clamps" to hold the original titanium struts on my mudguards, for saving a little extra weight, and a new Joseph Kuosac headset, as a proud owner. Also a new Ceramic titanium crank. I may buy a new titanium stem-post at one time also?

    • @DrJamesT

      Upgrading to a Ti stem post is probably the easiest weight saving method. Apparently it has a bit flex to absorb shock. I think it's all down to the suspension block.
