last week we put together a bike for jimmy entirely made out of parts from aliexpress
it looks like it could be comfortable what frame wheels the whole lot today is the first ride on
that bike i'm like you're putting me in the hut it's one by so he has to ride fast you okay no
i'm absolutely terrified i'm not worried about the frame or the wheels
just all of the connecting bits well i'm glad i'm behind i don't have to be a human brake
currently doesn't go into the easiest skier stop complaining it was freezing the chain
line's absolutely bonkers i'm too scared to get out of the saddle you can definitely
notice how light it is it fires absolutely terribly the brakes are weird the gears are
just not quite right but you definitely notice how light it is i'm glad we chose the
moistest the the most moist the moistest moistest day look my lens
has got condensation on it what the hell it's not raining but we're getting wet
so for people who watch the original build video there is a sensor empire pro group set which
i've been using before on this bike not on this bike on jimmy's bike
and for some reason it was shifting completely perfect when it was on my scott foyle my old one
and then as soon as we put it on jimmy's bike it stopped working and it was just skipping
everywhere we've got new chain new cassette new chain ring it should all be working smoothly but
for some reason it's not quite performing as it should the chain line though is absolutely wild
yeah because we've gone one by and it must be contributing to it a one by crank which
that is should have a correct chain line to run one by so a bit of a strange situation
uh we might have to try it with a different chainring ideally a smaller one for you as well
because the gearing is quite big let's see what happens there definite improvements to be made
other than that jimmy's flying this could be a fantastic bike if you got all of the bits dialed
in it's kind of cool having a really light bike you've ridden like stupidly light bikes although
that said some of the aero ones are generally heavier aren't they obviously they ride fast
this one is obviously disc brake and aero the new scott foil um yeah it's like just over seven kilos
with nothing on it yeah that means that is a good kilo and a bit lighter so it should feel snappy
as soon as you accelerate it from low speed i'm a bit nervous that's that's kind of the thing isn't
it because it's because it's still a the brakes are a touch suspect the gear the chain line is
really like making the brakes are very suspect i would not recommend them a lot of the stuff is
hilly i need to be in an easier gear even if i'm going to like give it a bit of bounce and i'm just
in my head i'm just like what if that's this if this slips off or something outside of giving it
give it the beans so i genuinely think that frame set and those wheels with the decent group set i.e
a sram or a shimano probably actually be a phenomenal or a compact or a compact
tram no but any any reputable drivetrain system on this frame set with this wheel
set i think could be a phenomenally good hill climb bike or just a bike in general
thanks francis i'm not convinced the brakes actually work anymore
do you think they got a bit wet a little bit there must be that moisture in the
air we were talking about earlier yeah it must be fast let's see how good they stop
i thought you said it never rained up anymore they're working they're working
you said to me that newcastle is in line with london as being one of the driest cities in the uk
we're not in newcastle pickle why are you walking uh the brakes
don't work like on the splits that aren't too steep it's fine but when there's a river running
down the road recap of the parts that are on this bike we have an elves vanyar super light
frame set we have elite wheels super light drive 4 tvs they're actually performing really well
the group set is as i said sensor empire pro which we've set up one by the seat post comes
to the frame the handlebars come with the frame and they are carbon as well there's a wafer thin
carbon aliexpress saddle unbranded and then to finish it off we've got a couple of non-aliexpress
consumable parts which is two two billito inner tubes and two tyres which we've had to change
from the ones the hutchinsons that i put on to victoria corsa evo cx's they're 28 millimeter
and we needed a slightly narrower tyre to be able to fit in this frame because it's a little bit
older style uh the clearance inside the fork and at the chainstays is a little bit tight for a 30
mil tyre and the 28mm tyres from hutchinson actually these courses seem to measure a
little bit narrower so that's what we've got uh currently set up for jimmy who's just walked off
we've hit a small problem with the first ride of jimmy's new bike video
in that we've lost jimmy jimmy's run off we hit a crossroads and i was laughing around with my
camera and jimmy's carried on but we don't know which of the roads that he went down so
well jimmy's run off literally yeah he was last i'm sorry he was running with his bike
i think he just assumed i knew where i was i think he's done a loop i think he's turned off i
don't think he would have carried on going further away from where we're meant to be sunny now jimmy
it's not sunny you're putting long finger gloves on
extra grip for the climb extra drip absolutely why you breaking hold on now oh just what you
want on a climb i think it's safe to say the zto brakes are not very good
do you think the uh constant brake rubbing negates the super light bike so it's the effective bike
weight now of 28 kilos yeah but when you're at a cafe everyone lifts it up and goes
but then they hear me coming in from two and a half miles away no you don't ride it i'm driving
so i did a little bit of research in between building the bike and us doing this ride and those
brakes the ztto ones have a bit of a reputation for being spongy and difficult to adjust we've
tinkered with them for quite a long time yesterday there was nothing we could do they always seem to
be rubbing or they're okay for a little bit and then they start rubbing again we have now come to
the safety of my kitchen where it's not raining so it's a lot more pleasant it has a lot of potential
it rides well it's surprisingly comfortable what part what pressure did you put in the tires
60 psi which isn't low for i safety tested it before you were gonna ride it thank you and you
handed me an unsafe bike thank you the saddle i noticed was a little bit sharp around the edges
which is not surprising based on how it looks the the shape of it is it is a comfortable saddle all
right it's not an offensive saddle at no point was i like this doesn't work for me obviously
saddles are very you know personal uh the fact it has no padding isn't that big of a deal because i
was wearing shorts which have good padding in them so i in terms of comfort it wasn't uncomfortable
i noticed it more than i noticed my saddle at first and then very quickly i was distracted by
the fact i was going uphill in hard gear and then it was raining there was a point where i was just
like i wonder if i can actually steal this saddle of francis i might actually give it a proper go
it doesn't feel like it's going to break or anything does it it's pretty solid do you think
the position of the shifters on the handlebars is too far forwards yes it's too over yeah they need
to be come up a bit they can't yeah because it was at the top of the like grip bit wasn't it yeah
yeah that that's not right of course you can run this bike with normal handlebars and normal stem
as well and that would be the solution these are the bars that they sell as an extra when you buy
the frame the problem is there's a little piece of thicker carbon that's on the handlebar that
stops you from crushing the bar when you do up the shifter and attach to the bar that kind of ends
very early so you can't get the shifter any higher up without risk of well i guess you could
but you risk crushing the ball it was definitely a reminder of how crap carbon rim carbon wheels
with rim brakes are when it's wet really the conclusion here is that there is two
major issues with this bike firstly the brakes not good enough not safe to ride in the wet uh
you ended up walking down a hill which is fair enough i wouldn't have wanted to be in that
position that can be easily rectified and tested with a different set of calipers which we will do
the chain line is the other problem so for whatever reason the crankset that we've put on
i don't know if it's a bottom bracket width issue you've used that one by
on other stuff and i bet it didn't have that bigger gap it just must be a compatibility
thing it was fun to ride and like you know the the way you really well i think where you notice
light bikes most is not when it's really steep but when it's actually like one percent two percent
where normally you'd be like wow this is quite this this is starting to feel hard but i'm not
actually going uphill very far whereas on that there was this couple there's a couple of points
where it's like two percent and it's kind of like it feels exactly the same as if you're on
completely flat i'm sure you notice it while you're going up the steep stuff as well but
that's just always hard regardless isn't it i just find everything hard jimmy i'm gonna retire soon
