- Alright, Four more.
Come on.
Oh yeah, that was a good one.
Oh hey, everybody.
I'm just out here jumping over stumps as you do .
Speaking of that, have you guys seen the new Stumpjumper
(upbeat music)
Can you guys believe that people have been talking about
specialized Stumpjumper for nearly 40 years now?
And sure these monitor examples,
might not have a lot in common
with that first mass produced mountain bike,
but the intentions are still the same
as they were back in 1981.
To be that all around trail bike,
that can do pretty much anything.
This is the all new stump jumper, 130 millimeter travel,
20 Niner's that's meant to meet that challenge.
Now I know what kind of looks like the previous stumpy,
but there are some big changes to talk about here,
especially on the suspension front.
But before we do that, let's go over the models.
If you're looking for a more forgiving bike,
you can check out the stumpy evil range
that my unpaid intern Mike Kazimer, reviewed last week.
With specialized has trimmed the normal stumpy range down
to just six models.
And they all roll on 29 inch wheels.
There are no longer any 27.5 inch wheel stumpy's.
Now having said that you can do a mullet setup
if that's the way you wanna go.
So the family starts with the stumpy Alloy that goes for
$2,200 American.....
And the next stop is the comp alloy for 3,200 bucks.
Now, as the name suggests,
those are both aluminum frames
and they use a different suspension layout,
but we're going to get to that in a few minutes.
Carbon bike started at $4,000 American
and there are a few to choose from,
but this one in front of me will it's the S works version.
And we know that S works means you get all the fixings.
So on this bike,
you're getting a wireless access drive train,
and a wireless access C post,
carbon revolve wheels and factory level suspension from Fox.
Now, all that adds up to 27 pounds on my scale,
and it's going to cost you about five and a half kidneys
or at $9,500 American.
Now, if you're a shoprat,
that's going to be building up your own bike,
like I know you want to,
you can also do a frame only it's $2,800 American.
Alright, let's do me not some frame details.
Specialized says that they've never made a trail bike,
this light, fast and capable.
And they also say that much of the carpet technology,
they learned from making the all new ethic
has also been put to use on the stumpy.
Now that all adds up to a 2,240 gram frame weight
with the shock and all the little bits that makes it
about a hundred grams lighter than the previous version,
and about 510 grams lighter,
than the evolve version of the new stumpy.
Also it's 371 grams heavier than the new Epic,
all the numbers there for you to compare.
Specialized told me that a big part of getting the frame
that light is eliminating the lazy carbon,
their words, not mine,
but what they're referring to
are the useless pieces of carbon
that are not adding any strength
in the tighter reaches of the frame.
Basically, if they're not adding any strength,
they're only adding weight.
So, why not remove them.
They also pointed out that having the heavier,
and stouter stumpy evil version of the frame,
allows them to make this one even lighter.
Specialized also told me that all the frame sizes are tuned
to ride the same by altering the tube shapes
and wall thickness.
And what that means, what they're trying to do,
is that an extra small won't feel overly stiff
compared to an extra large, which is larger.
It might be more flexible.
So all frame sizes should ride relatively similar.
SWAT is back, of course,
and the latest version is the lightest yet.
Specialized also explain to me
how they do this without affecting the frames rigidity.
And I'm impressed.
I sort of feel bad about making all those jokes
about having a big hole in the down tube now.
And of course there's room for a large bottle on top
of that SWAT hatch.
And specialized has also checked off all the trail
bike must haves.
That includes; a threaded bottom bracket shell.
There's a set of ICG Tabs around that Bottom Bracket Shell.
You'll also find plenty of frame protection
and pass through cable routing.
So you can just push it through
without having to scream at it.
(fan whirring)
Is that a giant vacuum cleaner?
I think I'm cursed when it comes to filming,
like the things that always seem to happen.
There's always something going on.
Gator, pulling a leaf blower,
while we'll try to film.
This appears to be a tank coming.
Alright, It's time to talk about something,
that the new stumpy doesn't have
and that's Horst-link suspension,
and to illustrate the difference between the two,
I brought along last year's bike
Now, Specialized has used Horst-link Suspension
since basically always.
And it's known for creating a bike,
that's active and forgiving,
and that sort of describes how Stumpjumpers perform
and this new bike,
well listen, an entirely different animal.
So what the heck is a Horst-link?
Well, it's named after a guy named Horst,
his last name was Leitner not link.
And it's defined as having the rear pivot
below the axle line.
It's axle path,
and a bunch of other sciencey things are determined by the
seat and chain stays.
Those are two bars of this four bar design,
but if we look at the new stumpy,
well, where the heck is the pivot?
Well, it used to be down here.
Specializes actually moved it up to here.
And it's a flex pivot instead of using sealed bearings
in a hardware.
Now specialized says that this saves around 55 grams
over the back end of the old stumpy.
So while the old stumpy is a Horst-link,
four bars designed with a pivot below the axle line,
the new bike with the flex pivot above
it actually makes it a single pivot bike,
with the linkage driven shock.
Now I'm gonna complicate things here
because the alluminium models,
well, they don't use a flex pivot.
Specialized says that that's a lot harder to do
when you're dealing with metal instead of carbon.
Those bikes use a similar Horst-link design
to the previous stumpy,
but Specialized as they've worked
to make them feel as similar as possible.
That's enough for last year's bikes.
I know, nobody cares about what happened last year.
All right, back to the the new bike
with the carbon rear end,
this flexion right here up in the seat stay,
well, it's not just random.
It actually helps the shock
into its travel like a negative spring
ever so slightly up into the sag point.
That's when it goes neutral and then slightly positive.
The previous Stumpjumper.
Well it's known for being active feeling bike,
if you're working hard with the shock left fully open,
but there's been a change of course,
over a specialized recently
with more emphasis on peddling performance
and having an energetic feeling bike.
I don't doubt that the new rear end plays a part in that,
but the Fox Shocks also gets a lightly tuned,
digressive piston.
And what that does,
it adds a tiny bit of low speed compression damping
to help that peddling performance.
I've been riding the wheels off this bike
for the past few weeks.
And you're gonna see a full field test review real soon.
But for now I will tell you that it pedals nothing like the
previous Stumpjumper.
It's an entirely different animal.
Alright, it's time to talk sizing and geometry.
And if you're looking for a medium or a large Stumpjumper,
well, you're not gonna find any of those words
on the geocharge.
Specialized S sizing is based on a writer's size,
riding style and preference with the idea being
that a rider can choose the reach
and the wheelbase that worked for them,
all of the bikes have short seat tubes,
so that doesn't lock you into a specific size.
Another thing to note on sizing is that thanks to it.
Reshaped top tube, the extra small 29 stumpy,
actually has more standover clearance
than the previous versions,
extra small 27.5 inch wheel bike.
Sizing runs from S one to S six.
And specialized says that a few are in a medium previously,
you might be on an S three,
if you're looking at the new stumpy,
but if you wanted more inability
I'm just making up words now.
You can move down to an S two that has a shorter reach
and a shorter wheel base.
Or if you want more stability, that's a real word.
You could move up to S four,
say you move somewhere where it's way steeper or way faster.
Let's go over some geometry numbers now.
And all of these numbers are in the bikes,
low and Slack setting,
because I know that's where you're gonna put it,
so that kids had a 65 degree head angle
and a 76 degree seat angle.
You get 42 millimeters of bottom bracket drop,
and that puts 333 millimeters off the deck.
Now there is a geometry adjustment feature.
It's a clever flip chip system at the rearward shock mount.
And that lets you adjust the head angle by half a degree
and seven millimeters at the bottom bracket.
So my S four size test bike has a 475 millimeter reach,
but sizing runs all the way from just 410 millimeters
on the S one to 530 millimeters of reach on the S six
So there should be a size that fits everybody.
I think that's pretty good.
Did you see that stump?
I am going to go climb that stump now.
(upbeat music)
Alright, everybody, that's it
for specialized all new Stumpjumper,
stay tuned for a full length video field test review
real soon .
In the meantime, make sure to like and subscribe.
And I'm going to try to get off this stump
without breaking an ankle.
(upbeat music)
Oh God , alright
I feel like.
Okay.
