this is my fully built up beautiful fully functional scot foil and this is a 300 pound
group set that i found on aliexpress today i'm going to put this on that and see how it rides
so for people who may have missed the first video on this topic found on the internet
a complete group set so cranks rotors chain everything for 300 pounds it's 12 speed carbon
should be about the same weight as shimano 105. size comparison of the two rear mechs this old
one's a monster so the version that i've got here is the complete group set as i said that's 300
pounds if you do a bit of digging you can usually find just the shifters the rear mech and the front
mech for a lot cheaper so if you already have a chain cassette and you don't need any of the
extra bits then that might be a good option if you want to experiment when i say experiment
i do mean that i don't know what this group says it's going to be like but we will shortly
find out hopefully if it all goes on properly these are cable actuated brakes means i've got
to change all the outers through the frames to make them work on top of that these brakes made by
nut are not reviewed very well either people have tested these before and the results haven't been
great the spirit of this bike build i want to use all of the original parts and do nothing special
to them to see exactly how well it works or how badly so we're installing these with regular cable
housing leaving the pads in there even though they might not be the best compound to really just test
how good they are if you were to install them yourself with no compressionless housing just
to see if they really are safe to ride before possibly upgrading them later in another video so
far everything is going quite smoothly i haven't got the tool to do my bb so i might have to visit
the bike shop in a minute now this definitely won't be relevant to most people's builds but
the rotor group set which i'm taking off this bike has um hoses it's hydraulic shifting as well as
hydraulic brakes and the hose very very thin and i was a bit worried about how i was going to do
the cable routing and get a cable through the frame without having to use magnets and stuff
but this hose is actually the perfect width of a gear cable so i just threaded a gear cable all the
way through it got mineral oil like everywhere thankfully it's not dot fluid so it's probably
way less poisonous so that's good but it does mean there's oil all over my studio now so um literally
everything is just slimy having said all that the old group set is one by and the new one is two by
so i'm still gonna have to internally root the new front derailleur cable probably have to borrow the
magnet thing from the bike shop you know all the bolts on here are actually quite nice quality
feeling at least i mean who knows if they're going to snap straight away when i ride them but
it all seems premium feeling whatever that's worth everything threads in nicely everything's finished
nicely the bolts on some of the stuff look kind of like titanium finish i don't know if it actually
is titanium it's kind of hard to show over video but certainly it feels premium in your hands
all of the group set parts except for the brake calipers they're the one exception they feel kind
of solid confidence inspiring but um not nicely painted not nicely made in the way a ton as well
always use grease when you're installing a cassette because otherwise it might not ever
ever come off again many hours later i may have got absolutely soaked on the way back from the
bike shop just then bb is now installed and the crank is in cable routing is also almost done well
the outers are in a small but potentially build ruining oversight by me there's no cable stop
in this frame so you technically well i don't know how scott usually do it we've had to bodge a cable
stop into the hole where your normal wireless stuff would come out because this is mechanical
you need a proper stop to make sure this cable has a lot of tension so then you can shift
like that luckily bike shop man nick had the genius idea of stealing this little plastic
piece that's like a stop that goes around the cable for the rear derailleur so we nicked that
used it upside down for the front mech and jobs are good go look at this date with me
feels like years i built a bike with cabled mechanical brakes because it's been years
since i built a bike with mechanical brakes now i've got to be honest i was expecting more
problems to occur during the installation of this the only real issue that i had
needed a bit of a hand with was getting it was basically a two-man job getting the cables through
the handlebars which is internally rooted and no fault of the group set any group set is going to
be difficult to install through the angles of the handlebar once it's in it's really neat and really
great we're getting there we're getting there i'm guessing this is why people don't live stream
bike builds because it's just well one boring two there's going to be loads of
a person standing still going trying to get stuff through frames gear cables are in
now to install the uh completely dry chain if you saw the previous episode you will
have seen the this is a ybn chain they're the chains that all the friction people
use and it's kind of good that they don't have any chain lube on or grease
like the packing stuff i'm gonna put this on i am gonna use normal chain lube though
because i'm not really one of those wax people yet i don't think i'm fast
enough to need um need chain wax comes with a little quick link in a suspicious looking bag
so front mech is actually shifting pretty well in the stand straight away uh i think it's a
fairly easy mech to set up because it has so many different trimming points sorry for the
squeaky chain i have this big studio here but no chain loop so i'm gonna go and get some lube the
chain before i ride it outside but for the sake of indexing i don't think it will wear out too
quickly all in all though the indexing has gone absolutely fine in terms of chain length i use
the trick where you go big ring biggest thing on the cassette without going through the derailleur
to get the length work perfectly first time or one last thing you'd probably want to replicate
if you were installing this yourself there's two cable routing options for the gear cables here
i would stick to the outside channel because this gives a smoother curve to the cable which should
end up with smoother shifting when you eventually ride it later especially if you've got internally
rooted handlebars like these only thing left now is the front brake and let's take it outside
seems to be all working nice so far brakes leave a little bit to be desired but they haven't really
bedded in yet so they're gonna get better they do stop me and that's with no compressionless
housing either with a big enough squeeze on the back brake you can lock up the rear wheel so
we don't really need any more strength than that modulation is obviously a bit lackluster just come
to the funny realization that all of my bikes at the moment are one by so i've forgotten how
to use the front mech naughty cross training testing bugs get you out bro best training
session i've ever had it's raining again i uh i booked this in for the uh wet weather brake test
jump test yep group set jumps sweet bit of air i've got to say i was most nervous about
riding these brakes on an open road outside so i kind of went up the hill and then back down
on the bits that are all pedestrianized but now i've done that to me these feel
safe enough to ride on the open road absolutely you can lock up the back wheel
front one feels strong i mean they're no hydraulics but good enough for the price
trying to get into this
he has got eyewear he's got glasses on they're protective
you've got protect safety glasses do you give a spin like what's your liability insurance like
absolutely fine i've tested it i've given it a safety check these turns are free right they do
feel spongy don't they i'm not unsafe feels like the old mechanical shroud i suppose they're just
like the paintings must be running out and copying this stuff maybe clearly not the outside because
the whole shift lever moves but inside maybe it's the same mechanism what the durability is like
i mean if it lasts wouldn't be a bad option for like a training like everyday group set
but obviously just we need to apply i mean that looks essentially everything's just copied from
other stuff as long as the spares are fairly easy i mean i assume you can just run normal 11 speed
chain normal 11 speed cassette 12 speed mate it's a task you 12 speed that's worrying so what we
need to do with this is what i need to do is put some miles on it and see how it fares with some
proper rides i want you maybe i might have a secret special surprise about the breaks which
may be revealed in the next few weeks or days because i think those breaks are they're crap
it's not cheating no because they're from aliexpress as well it was in the sevens before
oh exactly eight and a half yeah exactly so i've been riding this around all day now has there been
any negatives not really my front brake is making a real loud squeaking noise but i think i got my
grubby hands all over the rotors so other than that all good but as nick rightly pointed out
it is the longevity and reliability of the parts that we really need to test so the next few weeks
when i do ride my road bike it will be this one i won't treat it any differently i'll ride it hard
and we'll see if this group set actually lasts of course there are other things to consider as
well like how good is the qc how consistently made are the parts could you end up buying one
group set which is fine like this one and then end up with one not quite as good the next time
you purchase i may have got my hands on some more parts from the same manufacturer so if you enjoyed
