- Welcome to another absolutely awesome GCN tech unboxing
and today we have a seriously awesome prize.
I'm really excited.
And as ever with the GCN second boxing
there is a chance to win and one very lucky viewer
will win one Continental (pause) GP5000 tire.
(laughs softly) Only kidding.
Actually, five lucky winners will each win a pair
of Continental GP5000's but it doesn't end there,
each of the winners will be able to select
which size they want whether that's 650 or 700c.
They'll also be able to choose
the width so 23 up to 32 millimeters,
and whether or not they go for the Tubeless version
or the standard Clincher one like this.
How awesome is that?
(whooshing noises)

stay tuned to the end of the video.
But first of all I think we should crack open
some of these nice little boxes
and have a look at the tires.
The new GP5000 comes in loads of sizes and widths.
So I'm going to quickly go through them.
I've got most of them here
and they all come in these very sleek nice black boxes,
so let's get this one out.
(relaxing music)
A lot of people are exited about the new GP5000,
myself included, and this is for good reason.
The new tire is claimed to have 12% lower rolling resistance
than the outgoing GP4000.
And this means, well, you can go faster
for the same amount of effort.
The cool thing here is that this has now been backed up
by science and independent testing.
Dr. Xavier Disley at Aero Coach
recently performed some independent testing of the GP5000
versus the GP4000, both in 23 millimeter widths.
And he found that the GP5000 was four watts faster
at 45 kilometers an hour when both wind resistance
and also rolling resistance were both combined.
It doesn't end there though,
it's also claimed to offer 20% better puncture protection.
It's also said to be more comfortable
due to an improved construction and is five grams lighter
than the GP4000 in the equivalent 23 millimeter.
However, perhaps the most exciting development
is this, the Tubeless Ready version
which is a completely different tire
from the standard Clincher.
And you can identify it
by the fact that it says TL on the box there
compared to the standard one which doesn't.
As you can see up close it looks quite different
from the standard Clincher version.
You've got a little TL logo there on the side of the tire
but also a much more substantial bead
which is there to help get an airtight seal against the rim
when you're running it without an inner tube.
Now you can still use the Tubeless tire
with an inner tube in a standard setup
if you so wish or need to
but to get the maximum benefits
Continental suggests that you should use it
with Continental Sealant in a Tubeless setup
or in Continental's own words,
Wir empfehlen die Verwendung von Conti Sealant.
Apparently, running it tubeless with Conti Sealant
is claimed to give it 17% less rolling resistance
than a GP4000 run with a standard inner tube.
Aside from being tubeless,
the other really exciting thing for me about the GP5000,
is the range of sizes and widths.
So in addition to the standard 700c wheel,
you also have a 650b option.
And the widths available
are 23 millimeters 25, 28 and now (pause) 32.
Each of the winners, as mentioned,
will have the opportunity to pick the exact
size, type and width that they want.
Which is awesome.
Now for the part you've all been waiting for.
