welcome back to the videos i'm here with chris and today we're checking out his 4 000 pound
brompton 4 000 pounds 4 000 pound what are you gonna do about it i'm gonna attack you
so this is a 4 000 brompton and it's not actually chris's chris works for brompton so he's borrowed
it from work we've been hanging out and we had a pub lunch yeah we did we thought why not do a
video on it because it's a pretty ridiculous bike this one is the heavier version yeah there's two
versions with two different gears the lightest one is 7.45 kilos which is lighter than most road
bikes is that lighter than my bike i think so i think it actually is the one the thing at brampton
it's all it's always been about innovation and you can only do so much with steel i mean we've
been working with steel for 30 odd years so all existing bromptons have been steel except for
the chapter three except for there's the odd bits here and there and the the p-line that we
did which had like a a titanium rear triangle but we've been developing this for a couple of years
behind closed doors you know with the carbon fork with the headset here carbon handlebars
people have been wanting it they've been screaming for it and so we made it it just took us a while
carbon crank um it's got a new four-speed uh shifter that we we had to develop for
this rear triangle for it to work um so it's got normal dropouts now rather than before it had the
external um uh internal sturmy archer situation going on which was a nightmare when you had a
flat tire now he just drops out like a normal road bike and it's got two police in because why not
so chubilitos i think they're the lightest production in a tube on the market and now
these are the lightest they're definitely the lightest because they're tiny yeah they also do
ride really nicely it's a noticeable feeling when you put jubilee toes in like instead of a
normal butyl tube it's more like road bike parts the headset is fsa it's like a 1 8 is it so yeah
you could put chris king in there if you wanted to or there are other headsets on the market of
course but you're all like a chris king because your name is chris yeah and i'm a king so we made
our wheels as well so these are super light wheels uh different hubs than these ones um i think the
only parts that are the same on all bromptons are the brakes so everything on this bike has been
changed everything else every single millimeter of this bike has been re redesigned re-engineered um
for it to be the lightest brompton ever produced so if someone wanted to buy the absolute lightest
yeah there's a one speed version there's a one speed this is called the urban this is the full
speed and it comes with a new uh compact shifter system which is made for people that live in um
slightly hillier cities i would say but if you live in like central london and you're just going
around the centers of where your place pre or or your place wherever you live is nice and flat then
you just get the one speed and it's even lighter you're all right what i was so confused lift it up
that's not dedenium yes all of it carbon forks robin cranks yeah
how do you change gear with the gear shifter oh i made it harder
to be fair the gear shifter does work backwards to how you'd think because yeah yeah
he was in the small ring why are you in the small ring this is the big ring hill
nice with the bottle i don't know think i think mine is lighter still what how much does this
weigh it's smaller it's 7.45 that one oh yeah should we see if yours folds folding challenges
all right what are you doing oh
don't scratch my seatbelts how yes no it's been too good yeah it's totally wrong that's nice
you don't know what you're talking about and that's it's done
oh god how quickly can you fold a brompton now that you work there i think i can do it in
around 15 seconds i think prove it two one go
seven seconds eight seconds
beat your time 14 14 seconds 14.76 seconds i thought he's about to say 14.9.99
and that's with the pedal as well yeah so hang on you just pulled the pedal off
what did you just do usually the brompton will come with like a folding pedal and just fold
upwards um the new pedal on the t line is is this new system uh where it clips into place
just like so um when they take it off we just squeeze them in and it comes out is it magnet
and then just goes in it just goes into there so that is magnetized and that's it and then you just
away you go onto the tube onto the bus and yeah not to mention as well we also
made we also invested in a new laser machine so all the titaniums they have like uh oh it's all
laser etched this it just looks very premium i think so look now the song comes out after we're
done with the film we've been freezing standing by the side of the road now we're heading back
into richmond gonna check out chris's little bike workshop cave what would you call it headquarters
my wife would call it a mess it's a light bike but it doesn't make hills any easier but you do an
electric one yeah we'll go pick it up at my house now we'll stop over we've actually got one yeah
