welcome to a brand new series on this channel which doesn't
actually have a name yet and it's going to be very quick because it is
freezing in the northeast today this is trevor how's it going he owns the yellow and there is
a viello bicycle in front of me it's yellow you probably may recognize it already from other
youtube fame it's been on dave arthur's channel before but here is a bike check for you to watch
you got a puncher uh you can't do a bike show alright check with a punch it's only flat at
the bottom this is my vlog plus one and when i say mine it's literally mine so the yellow's a
brand that myself my dad launched in 2018 been in the industry 35 years as a distributor of
other people's brands and we decided there's an opportunity for us to step away from all of that
corporate style and do our own thing um so we initially launched with our v plus one grab the
bike and then the year after that we um we were looking for opportunities in the road
sector to do a road bike but we didn't just want another me too product another road bike
so we were looking at um where are the opportunities in the road bike market
and the lightest bike had been done by you know in the early noughties there was like sub 800
gram frame sets and everything was chasing weight aero road bikes we didn't have the r d budget that
a lot of big corporate brands have to chase you know big error wind tunnel data endurance and
comfort we had a lot of that already covered with the uh the v-plus one but what we did see on the
horizon was manufacturers pushing more into one by and that got us thinking if we designed the
frame that was entirely optimized around running a single chainring on the front without a front mech
what would that give us what does that free up what opportunities does that get us um we still
want it to be modern we're still gonna have disc brakes we're still gonna have you know comfortable
um for the road surfaces around here office one is where is what we came up with we literally sat on
the italians on the other side of here drew it out on a napkin and started from there so office one's
full carbon frame set this is the alto version of the frame so this frames 880 grams the alto
road bike with us is a wireless only frame set so there are no shift cable ports on the frame
nothing at all there are only brake hoses so you have to ride surround you have to ride
shroud unless somebody else comes out with a wireless group set as it is right now you have
to ride shroud it is entirely designed for our chain ring and so we do our own cnc yellow chain
ring that matches with our bottom bracket reason for that is i'll show you on the underside of the
frame the bottom bracket is pushed out as wide as possible because we're not having to accommodate
an inner chain ring on the inside of the frame we can have a bb and chain stays that are symmetrical
so you have a straight line all the way through so from a power perspective that section is 32
percent stiffer than the equivalent on a two by frame and we can measure that we can show
that and demonstrate that and all that extra material just makes it so much more stronger
frame is designed to be relatively error we're not claiming it's the most aero frame set in the world
and it has an uh wasted hourglass head tube inch and a half inch and an eighth head tube that's
designed to be aerodynamic there are camtail profiles down the down tube and across the seat
tube then you get to the back end the back end is the bit that everybody comes to it's the first bit
that people come and point at in terms of why are the seat stays like that they're designed that way
because they're designed to be aero but they're also allowed designed to have a small amount of
mechanical flex to it as well you've got something that is comfortable optimized around a 30 mil tyre
for the road service vibrations then we get a bit lumpier you've got and the seat stay that gives
you a bit more comfort as well we finished the frame set with our own one one-piece handlebar
and stem unit just a full carbon fiber handlebar there's no brake hoses on it visible at all they
all go in through the stem in through the bar through the frame set and then out the chainstay
or outside the front of the fork we also use our own axle design as well so it allows you
for a fast quick release axle um which makes it lighter again so the handlebar and we designed
that so there's a slight step to it the slightly swept back so they're designed to be comfortable
and modern the frames that we were looking to design we weren't chasing pro tool athletes
we know our customers aren't that less than one percent of elite level athletes that want to be
in the most aggressive racy position and by not being constrained constrained by the front mech
we're able to tweak the geometry so the seat tube ankles slightly further forward allows to open
your hips up a bit more you're not in a super super aggressive position it's designed to be
comfortable and fast we've got a camtal aero seat post again it's our own design and then there's
this one this one's mine so this one is set up in my spec the way i'd like it i have tram red
access uh etap access shifters on this and that's paired with a force rear mech on the back of mine
and a 1036 percent i also run a 44 tooth chain ring on the front you can go on the
road we generally expect either a 44 or a 46 for our one by setup it depends on what
you want to use it for you can come down to a 42 if you're touring or bike packing
there's lots of different options there i think a lot of people's fear on one buy is
they worry about gear range anxiety and worrying about having enough gears to climb and enough
gears to descend still at speed i think a lot of people's fears sit back from 10 speed systems back
in the day or even 11 speed systems this is a 12 speed tram system there is 13 speed offerings now
you know with some of the mountain bike offerings from sram you can get a 1052 cassette you could
climb up the wall with that it's so there are so many different options out there wheel wise
i've got three or three fire crests on this one they're 30 mil wide and 40 mil deep and
these are pro one uh tires again 30 mil on those so they're super comfortable
low pressures designed really just for that broken tarmac surface you can just ride and float along
all over the northeast all over the northeast everywhere today yeah exactly i've paired it with
a fabric uh carbon flat saddle this is carbon rail fabric saddle which matches up with their silicon
bar tape we wrap the bar tape slightly differently so we wrap it outside in rather than inside out so
you don't end up with the silicon um you don't have the insulation tape that you would normally
put on your handlebar to finish it and tape it on so you just end up looking really really neat
yes i am running spd mountain white pedals on this but hey it's what my gravel shoes are so
comfortable that i will not ride anything else at the moment i have a lightweight edel helper
bottle cage which is 16 grams for the bottle cage how about how much money does that cost
it's 90 quid that's exactly what i missed anything else on at the moment oh of tram red crank arms
so our chain rings fit the direct mount fitting for the sram crank arms we have our own chainring
and crank options as well but these red crank arms are so light for a carbon crankset weight wise the
bike comes in they're about seven and a half uh kilograms it's super light it's super comfortable
and it's all go anywhere road machine when we're looking at designing the bikes it's so easy to
go to asia and take it up an open world product stick your name on the down tube and look like
everything else um it's the exact opposite of what we wanted to be we didn't want to be shouty
graphics and too loud so we want to adjust the logo just on the top tube out of the usual place
you know it's a type of thing that you can look at you'll notice that there's no graphics or acronyms
or made up bs on the frame it's designed to have a conversation with somebody about the way that
the bite looks in a couple of colourways so this one's mustered with the anthracite on the inside
it's we can do it in the reverse as well so anthracite and mustard so you mentioned
symmetrical chainstays and you've been able to do that because you're only running one
by on all of the bikes is that why you have to use your special homemade chainring as well yes
what's the situation yeah so the reason being if you look imagine your normal two by setup you have
to accommodate that inner chain ring so you end up with on a traditional road bike a chainstay
that's wide and flat on the non-drive side and a chainstay that's tall slightly taller and narrower
on the drive side you those that mismatch creates flex you end if you put the power down you can
flex the frame more through that area the way that we've designed it by being able to push the
chain ring out as far as possible we can make the chain stays as wide and flat on both sides
so that symmetry gives you a mechanical shape that makes the frame super strong and when you stand on
the pedals it just wants to go well i think you should be very proud this is exactly the kind of
bike that i love to feature on my channel there'll be more smaller brands doing cool stuff featured
in videos going forwards uh i really need a name i need a name for this it's like bike for tuesdays
any questions for trevor down below but also suggestions for what this segment can
be called let me know did you enjoy it cheers i enjoyed it you're going to eat pizza now yes
