welcome back to Berm Peak I'm Seth and today we're going to be doing something a little bit different
but kind of the same I have here my old trail bike last time we built up a new one that's
going to be what I ride from now on and somebody in the comments said why don't you turn the old
one into a slopeduro bike now I wouldn't be the first one to do that a lot of youtubers
are making slopeduro bikes but I think I can do a better job of explaining the process and
what exactly a slopeduro bike is simply put a slopeduro bike is a trail bike converted into
a slopestyle bike so we have over here Kevin's slopestyle bike and what it is basically is a
full suspension dirt jumper it's a little bit smaller than a trail bike it doesn't have gears
at most it has a few gears in the back just for changing your speed much stiffer suspension it's
not made for climbing you can't raise the seat up so why would you build a slopeduro bike why
would you take a perfectly good trail bike and turn it into a slopestyle bike that's not
really a slopestyle bike well for one you do it for fun to repurpose an old bike and
in this case we do a lot of things on Berm Peak that we could actually use a slopeduro bike for
it's more reliable because there are less things to break it performs better on jumps
and I guess you can never have too many bikes right so let's get my old trail bike cleaned
up I'll start taking some parts off and I'll show you how we make this conversion
oh yeah all right on to the bike wash
Oscar earned his time out
come on buds
so as this bike dries off I have some parts that I have to paint red but I don't have to paint
them red but we're going to do a fun color scheme because it's a slopestyle bike or a slopeduro bike
he's the supervisor
so slopestyle bikes are usually either single speed or they have like a downhill drivetrain
they're not really made for climbing so I had this oval chainring that's made for climbing
we're getting rid of it we're going to put this round one on
all right so now instead of a cassette on here we're gonna put one single chain ring my gear up
front I believe is a 30 and so I'm going to use a 16 tooth at the back and that's going to give us
the gear ratio that I want to be able to sprint uh you're not really going to be able to climb with
it that well problem is you go and put this onto the spline of a cassette and it can slide back and
forth I'm going to have to put spacers in it and those are the ones that I painted black and we are
done with the back so i've shown in single speed videos of old that if you get the right chain
length you don't need a tensioner or anything like that but on a full suspension bike you pretty much
always need a derailleur or a tensioner because as the suspension moves there is what's called
chain growth so the distance between here and here actually changes and so the chain will get loose
pop off I have a chain tensioner I bought this for flip bike so it's a
16 dollar chain tensioner I have a feeling that I'm gonna be disappointed with this
it seems like there was another component to this that somehow is missing so um
I do believe we're screwed come here a little chain tensioner this won't hurt that bad we'll
order a new one off of amazon we'll order a new one off of amazon and everything will be a-okay
totally massacred the chain there it goes where did my
where did my master link go I honestly probably want a better chain tensioner than this one as
well but this is going to keep the chain tight because it's spring-loaded so we're going to
route the chain through here up and around we just got to choose a length so I'm thinking
we'll let this really get tight like there that'll give us a little bit of space for chain growth
now you can just gingerly sneak it on there so now that keeps the chain nice and tight
all right so now we have a single speed full suspension but how are we going to
make this into a slopeduro bike first of all the suspension needs to be much much stiffer
on a slopestyle bike it barely moves at all it's just to absorb those really hard hits
because when you're diving into a really steep landing the last thing you want to happen is
your suspension to compress and you go over the handlebars and when you're pumping up a jump you
want as much of your power as possible to transfer into the bike too much suspension is not good so
I'm gonna put more air pressure in the fork that's a really simple solution and then on the rear
where we have a coil I'm gonna add a little bit more preload but also put a heavier spring on it
this spring is a 450 I just so happen to have a 500. and now we're going to throw the 500 on there
preload the urine out of this make sure that those pumps
transfer into the suspension it's gonna feel totally different than my trail bike
we're gonna start with five additional clicks and then we'll take it from there
and we especially want that slow rebound on the rear so that we don't get bucked over
the handlebars okay so in the event that I want to do bar spins I need to have an extra
long brake hose that the bars can spin around a couple of times hell performance like a year
ago sent me a bunch of braided like heavy duty brake lines and they have red ones
oh we got no spillage okay now we're dripping stuff now we're dripping
this is a lot more work than a normal brake hose like use the tool that gives
you the highest chance of injury to remove 10 millimeters of hose from the outer shell let
me look at the instructions this is nor this is different from the other hoses I don't know if
I'm advanced enough for this so you push and rotate that down now you take this and you
wow this is some heavy duty crap god it's a lot of work but I got to admit
it's pretty bad ass I mean look at that okay so what's the next step
alright so we'll just fill this up and then see how she works I mean that's kind of a
miracle I can't believe everything I went through to put this in there's no leaks
everything feels good this is some nice brake hose and the fittings look really
good but man it's a lot of work and I got to be perfectly honest the red hose is an abomination
this bike originally had a Oneup EDC in it we took out we're just going to run
the cable through this hole that goes all the way through and then we'll be
able to spin the bars around as many times as this cable will allow now as you can see
it's so ugly
oh next up seat post so on a slopestyle bike you're not climbing up hills or riding long
distances so the seat post just remains really low so it's perfect for jumping
and the most important thing is reliability so there's no dropper post or anything like
that unless it's Kevin's slopestyle bike he put a dropper post in his
oh man professional who wouldn't just do that on every single bike just match it
I don't know why Marzocchi didn't do that because I mean it's red well I'm gonna have
to see how she flies and make some adjustments but first I think we gotta stare at it
all right time to shake down the suspension a little wet out today
actually feels pretty good alright let's see how she flies
she hits hard actually I have the compression turned up let's turn off the compression see
about to say that's hard even for a million psi
it just feels so reliable like you take a crank you don't have to worry about
your in-between gears it's stiff you can pump I think she's ready for the trails
so quite obviously I love the way this thing feels sounds awesome not so much in the rock garden but
on jumps it feels amazing am I going to use it I'll probably use it the red brake cable is kind
of growing on me like I said it looks like a an artery like that was just ripped out of somebody's
throat and wrapped around the bike and just all over it looks like the bikes like veins are out
it looks immature and childish which really is a good personality for a slopeduro bike to have
so let me know what you think have you built a slopeduro bike what type of mods are good to make
a trail bike into a slopestyle bike I hope you enjoyed messing around with us in the
shop today I hope you learned something and if you didn't I hope you at least
found it entertaining thanks for riding with me today and I'll see you next time
uh
