- This weeks GCN unboxing comes courtesy
of the masters of aero.
Zipp.
What lies inside this box could unlock
considerable free speed.
And no, it's not a tiny pair of aero wheels.
When I say 'free speed', I mean free speed.
Firstly, the product in here
could make you more aerodynamic.
And then secondly, for one lucky winner,
this box and its contents will be shipped straight to you.
That's right. Free speed, delivered to your door.
(doorbell dings) Yeah
Now, as usual, I will tell you
how you can enter this competition at the end of this video.
Right. Let's put you out of your misery.
What is in this box?
(intense music)
Look at that.
The Vuka Aero bar.
And yes that is Vuka as in Sambuca.
Not vuker as in (bleep).
Anyway. That being the base bar,
that also means that if I have a little look around
I should be able to find these.
The Vuka Evo Carbon Extension, which of course,
pair up with that.
And yeah both of them are made
out of beautiful carbon fiber.
Using what's called exogram technology.
So that's the same method of manufacture
that's used to make SRAM's red cranks for example.
So you can imagine that you could put considerable torque
through these.
Making it out of carbon fiber
means that all of the shapes and cross sections
can be optimized for aerodynamic.
Of course, they do conform to the usual regulations
of three to one, width to depth ratio.
Particularly this air flow section here.
You know every time I say three to one ratio,
I'm sure I can hear thousands
of tri-athletes sniggering.
Yeah, probably in their compression socks.
Now one of the key benefits of the Vuka Aero
is it's ability to be used with a standard stem;
giving you a huge array of fit opportunities.
Because it's all very well having a super aero handlebar,
or super aero wheels or an aero frame.
But if you, yourself are positioned more like
a sail for boat than Exocet missile
then you're not going to be going very fast.
It's all really well having a super aero bar,
but the stem itself is likely to generate
a load of turbulence.
Except
Tada!
That's right. Integrated stem cap.
So not only does that maintain
the air flow cross section across the bar,
but actually it's not just pretty. No, no.
That increases the stiffness of the bar. By five percent.
Now while we are closely inspecting our aero bars,
you will notice here the rapid routing cable exit port.
Now Zipp have designed it to be more straightforward
to set up and therefore quicker.
So you will spend less time faffing around
with convoluted cable routing and hopefully,
maybe even squeeze in an extra training session.
Then, we can also notice here
the sand painted finish on key sections.
You could, should you wish, actually dispense with bar tape
on this section of the bars.
I'm not entirely sure you'd want to do it here,
on the base bar.
But definitely here, on the Vuka Evo Carbon Extensions.
So called because the Evo's shape
has 20 millimeters of inward rolls
so it puts your hand in a more aerodynamic position.
And then they come in two sizes.
They've got the 70 and then the 110,
which is these ones here.
And it refers to the amount of lift that you get
between the base of it and where your hands hold onto it.
And then, if you look very closely at the end here,
you've got replaceable end caps.
So you could fit your SRAM blips
very neatly into the end of your bar.
If you are lucky enough to be rocking out
SRAM Red Etap of course.
They're also slightly longer than previous versions.
These are 380 millimeters as opposed to 360.
Your Vuka Carbon extensions, of course,
bolt on to our base bar.
I've assumed that you realized
that cardboard wasn't actually structurally important there.
As I was saying, the Vuka Evo Extensions
bolt on to our aero base bar here.
But in the box, if we have a little rummage,
we can find a load of risers
that will increase the stack.
I've got various different ones,
from 5 mil all the way up to 50 mil here.
And that raises, not only the extensions,
but your arm rests as well.
And there is, in total, an absolute ton
of adjustability in here.
And that's really really important
because tiny adjustments in this cockpit area here
can yield big big differences
to your overall drag coefficient.
Of course, dialing in precise fits is a complicated task.
So Zipp have created the Vuka Fit app.
Which is designed to simplify the process.
So you input firstly what bar you want,
so I've got the Vuka Aero bar of course.
Then you input your own reach and stack measurements,
and that's taken as the top of the arm rest
as the key point of the measurements.
Then, you type in the reach and stack of your frame.
Plus the height of your headset and any spacers you got.
And then, the clever bit.
Firstly, it tells you what stem you need
to get the base bar in the right place.
And then, when you've chosen what extensions you want,
so we've got the Vuka,
there we go. Boop.
Finally, look. It spits out the exact measurements
you need to therefor put your armrests and extensions
in exactly the right place.
So there you have it then.
Your free speed all wrapped up
in this really frankly stunning
carbon fiber Vuka Aero package.
How do you get free speed delivered to your door though?
I know, you waited patiently for it.
Well all you got to do is enter the competition.
To do that you've got to go into the description
beneath this video and click the link.
It is as simple as that. Actually no it's not.
You've got to answer a question. (laughs)
And then, you keep your fingers crossed.
It is as simple as that.
Right, in the meantime, whilst your waiting.
Firstly make sure you subscribe to GCN,
it's completely free.
You get easy access to all our videos
and that it gives you something
definitely to do whilst you wait patiently.
And then if you want more content about Zipp,
well we've got two absolute bangers for you.
Firstly, if you click just down there
you get through to our Zipp factory.
Where they very kindly showed us how they make their wheels,
Which is a brilliant process.
Then also, if you click down there,
we've got their previous product release.
Before these Vukas, they released
the 454 NSW wheels.
