today we're at backyard bike shop building my new cross country mountain bike the scot spark
rc super sonic edition hidden shock tony's got one of these yeah but mine's better than tony's
supersonic that means it's faster supersonic means if you're riding
with tony you need every bit of advantage you can get that is true
you know how long it's been since the film the mountain light bulb
actually can you remember how to build mountain bikes not really like and loads of stuff changed
since i've built one so it's a bit of a i've not even serviced one in two years it's gonna be a
long night luckily the parts that we're putting on here are parts that i bought the other day which
are sram axis eagle it's the mountain bike stuff it's all gold and it's also wireless so basically
all nick has to do is kind of tighten it on and it just works right that's the beauty of access it's
that oh well the axa will call it's access meaning everything works together the mullet group says
we run uh euron road levers road brakes road chain set but then you're on the mountain bike rear mech
mountain bike chain the only thing that's specific to the different ones is if you could go mountain
bike neck you have to have a mountain biker safe and a mountain bike chain if you're on
a road rear mech it has to be a road chain in the road cassette which is the flat top the weird flat
top yeah yeah yeah other than that everything works together your wireless dropper post will
be fitting tomorrow after the last video he's up sold me a dropper so this is a temporary seat post
that's going in which will be used for a future build which i'm buying today very expensive right
yeah yeah it's still 50 quid it will make for a very light other build which will be coming
up maybe in a few weeks or months time uh but temporarily because i want to ride this
tomorrow maybe with tony we'll hit the trails uh i just wanted a seat post in there while we get
this dropper sorted which is a slightly different size to the one we've got here so you put a shim
interesting fact i don't actually know if this is still true but i think you can
have the steerers replaced on these folks so if everyone need a longer one you can
just buy it i might be wrong everyone goes cuts out for sure for a long time
on that setup now we have to find a star nut what this is is a starfangled nut so
when you don't have a carbon steerer you basically have to bang one of these in
inside the fork so you've got something for the headset screw to
thread into back in the day you used to have a tool that just threaded in which is like a
punch and then you hit the punch to get it in yeah to kind of make sure it's straight
that's what i used to use you have to get the right depth but if you have this this one
place it on top
sound changes
perfect depth perfectly straight magic slash witchcraft sealed up so there is a rear shock
inside this frame which is quite cool because your suspension doesn't get covered in [ __ ] but also
looks really neat it's 120 millimeters of travel front and rear so it's two centimeters more than
what i've been riding on the previous bikes the geometry is also significantly more slack than
on the other bikes that i used to ride this is scott's sort of attempt at really pushing
the boundaries of cross country as it's become more aggressive and more technical
as time has gone on you've got enough cable there so just fix it here yeah it looks good that
little slot you've got at the bottom of the bike i'll just open it up and stuff it all in there
you've got plastic wheels as well we've noticed lately that carbon gravel wheels actually hold up
loads better than alloy you saw graham earlier yeah his wheel had like 17 dents in it
where we've got nobody destroying any of the carbon wheels yet so um it must be slightly
more impact resistance and the envies we sell have got a warranty saying like the
actual lip is four and a half more thick and they say that if you were to somehow break
it they'll just replace them granite juicy nipples do you want speed or do you want grip
mountain bike tire is scary
so to get the chain line right on this bike we're actually using an absolute black zero offset chain
ring um you can get a crank to achieve the same thing but there's stock issues currently in the
cycling world as people know uh so we're gonna fit this on and hopefully it'll work
guns don't kill people rappers do got some interesting pedal stuff to tell you when to fit
your pedals mounts and bike pedals are quite good for um clearing mud and clip on both sides when
you're trying ride offs you don't have to look down it makes a lot easier but people start riding
road pedals and the big thing is road pedals offer more stability and it's got to do with platform
engagement with the issue the average shimano pedal the pdm 520s 540s have roughly 122 square
millimeters of engagement the xc pedals actually goes up quite a bit they go up to 250 i think
and then the xtr drops back down to 188 so very light pedals good pedals they last quite long
but they're not as stable looks pedals basic pedal starts at 350 square millimeters of engagement
because they've realized that sideways doesn't really matter from unclear and so forward so that
just made a lot more stable i've seen the more expensive ones that i'm riding is 515 so that's
more stable and quite a lot of road pedals out there so you don't lose the stability factor but
you still have the mud clearance and everything so arguably if you had a stiff mountain bike shoe
that should ride even better on the road pedal james will be able to probably comment on this
better but surely that must have a positive effect as well on knee pain and things like that
most of the time if you make straight it tends to just show perfectly out of the box
um but the easiest thing i've found is if you put in one of the higher cogs you actually visually
look from behind while you trim it you can kind of see if it's the gap between the chain and the
next cog up and the cog down is evenly spaced it's probably the best indicator let's see if it must
shove smoothly through the gears and you can adjust it needs to be here it's very
straightforward it's much easier than cables because you don't have to worry about with cables
you have to worry about whether this drag is the routing gone properly is there is it gonna stretch
um how's it going through the frame what's happening in the ferrules if your ferrule is quite
tight after a while they might actually bed in and then your gears go out again where with this
when it's set if your gears go out something's wrong it's a bent hanger right actually or these
obviously like you've seen one of the previous videos you can kick them and i'll just disengage
just like on tony's bike video there's a thing on the end of the throw axle which is the lever for
actually doing it up but also has a tiny little torx on the end of it which you can use to
adjust your seat post and your handlebars and your stem if you have a separate stem
which is my case it's just a one piece thing what near enough every bolt in this bike
is talked which is well it's great yeah almost everything you have to adjust i could have built
the bike with just that tool i don't know why he bothered with all of this nonsense moment of truth
ten point four six kilos for full size massive tyres and about four liters of sealant in this
so we're in business the bike is finished it's now the next day and here's a full rundown of my
new scott spark rc with some pretty cool stuff on it as i said the frame is a scott spark rc
size medium this is a super sonic paint job so limited edition and one they did for the
olympics this is a cross-country bike but has 120 mil of travel front and rear which is slightly
more than a normal cross-country bike would have geometry is a little bit different to your usual
cross country bike as well you have a slightly longer top tube slacker geometry which means
it should be better at going downhill i'll be testing this in tomorrow's episode the frame
comes with synchro's bar and stem which is all nice and internally rooted the garmin mount on
the top which is a good place to put your garmin because if it's sticking out the front and you
crash on a mountain bike there's every chance that you might snap it off so this is where most
xc racers will put their head units synchro's grips these feel really nice temporary seat post
is a usc ultimate which is carbon and very light with a celasan marco short nose saddle to go with
it which i borrowed from nick on the back of the saddle i'm running a pretty cool little saddle bag
which fits on with magnets and is made by fidlock same company that make my bottles which are also
fitted on with magnets they're quite popular with enduro riders and other mountain bikers because
they just don't fall off when you're riding we've got fox factory 34s on the front
these are 120mm of travel as i said connected up to an interesting lockout system which got called
twin lock these levers actually have three positions you've got completely unlocked so
if you're riding down a trail you have halfway which means if you're riding on probably something
like this and you want your suspension to be kind of half on not quite as squashy but you
still want to be able to get the power down and then you've got fully locked out if you click
it once more nice to have the options i have yet to find out what it will be like riding this uh
but i'll give you a bit of a longer term review over the next few weeks and uh see how often i
use that middle position because that's the new thing compared to my old bike the same thing
that's attached to your handlebars you actually have a third lever which i've taped out the way
but you can fit a dropper post there so it's quite an all-in-one solution to all of the little things
that you have to have on your handlebars group set is sram eagle axis so this is a wireless
mech with a 1050 cassette one by 34 on the front and this 34 ring is actually from absolute black
syncross silverton carbon wheels these are one down from the super top end one piece carbon wheel
that scott make or syncros make set up tubeless with my hutchinson krakens which are the cross
country tire that i rode all year last year work really well for most conditions and very easy
to set up tubeless because hutchinson invented tubeless so if you want tires that go on easily
hutchinson's to finish things off and to keep things matching we've got sram rotors calipers
and brakes as well got 180 on the front which did need an adapter to fit on this frame which despite
the adapter still looks very neat and then a 160 on the back so loads of stopping power that is a
bigger rotor than i had on my old bike oh and then shimano pedals which don't match
the sram at all i hope you enjoyed the build and a quick first look at this bike let us
know if you have any questions in the comment section down below massive thanks to scott
for supplying the frame and uh i hope i can do it some justice on the trails this year if you
enjoyed this video it may be worth you checking out my nice bikes playlist on this channel where
i've got loads of different bike checks from different people talking through their builds
and some nice shots of the bikes as well stay tuned for more thank you for watching and goodbye
