- Welcome to another amazing GCN Tech unboxing.

So, here it goes.
First up, I just want to say
I feel like a kid in a sweet shop right now.
And, can we talk about these boxes
'cause they look seriously cool.
They've got this kind of GRX branding on them
and it's kind of dirt and grass and there's a cross.
It looks really cool.
And it's a nod to what GRX is for.
It's quite a nice contrast for Ultegra endurance boxes.
If you've not seen them,
they're all gray and black and metallic and stuff.
But GRX, if you're unfamiliar,
is the world's first mixed surface
and adventure riding group set.
Now, if you want to find out about it in more detail
than what I'm going to go into in this unboxing video,
thankfully you can because I made a first look video
and I'll include a link to that at the end of this one.
Now, when I did that first look video,
Shimano supplied me with the mechanical version of GRX
but this is a higher spec version.
This is a top of the range Di2 version.
And it doesn't just have electronic shifting
making it better, it's also got better brakes too.
So, let's have a look at the shifters.
Clear this stuff over here.
Oh, these look nice.
So, these brake levers, they look good don't they?
They feature something called Servo Wave tech.
Now, this is something that's borrowed
from Shimano's top end mountain bike brakes.
And it results in a non-linear lever pull.
What that means is that the first part of the stroke
when you pull on the brake is quicker
and then it gets progressively slower as the brakes contact,
well the rotors contact the pads.
And the idea behind this is that it increases feel
and modulation, according to Shimano.
As you may be able to see, the levers have a revised shape
that's very different from a standard Shimano road lever
and this is intended to improve ergonomics,
especially when riding on mixed surfaces.
And there's also more texturing and different texturing
sort of on the hood area here
and also on the side to give it a bit more grip,
like when it's wet and dirty and stuff.
And, it's just a really nice sort of matte satin finish.
I think that looks lovely.
I'm going to carefully put these back in the box.
Because I really want to open the derailleur boxes
and have a look at those.
So this is the rear mech.
I think this is the most exciting one for me.
Look at that!
I mean it looks like it's part of Darth Vader's face.
Look at that!
(laughs)
So this is the two by Di2 GRX rear mech.
But there are also one by specific GRX mechs, too.
And this one's actually rated up to a 34 cassette,
thanks to this really long cage down there.
And this little switch here is really cool.
That is actually the clutch on-off switch.
Now, the clutch is used to maintain
chain tension on rough terrain.
Tasty tech, that.
This is the front mech.
Well, I hope it is.
Yep.
So, visually it's very similar to an Ultegra Di2 front mech
but the styling's different so you've got that
matte satin finish that matches what's
on the levers, it's nice.
And you got the GRX badging there.
Looks very cool.
But it's crucially different in that it's designed
to sit 2.5 millimeters further outboard from the
bolt and bracket than a standard Di2 road rear mech.
Why?
Well, if you want to find out why,
you're going to have to watch my first look video.
Link will be at the end of this one.
All right, let's just put this away.
And on to this.
Now, this big box contains the chain set.
Well, at least, I hope it does.
I knew I shouldn't have watched Seven last night.
(suspenseful music)
Phew, it's a chain set.
Again, there are different options available.
Two by, such as this.
But also, one by specific chain sets.
The ratio on this two by chain set is 48-31,
which is a slightly easier gear ratio than
a typical 50-34 compact road chain set.
And the reason for this, is that it's designed for
if you've fully loaded your bike up
with luggage for an adventure.
Or, for getting up short, sharp, steep gradients
when you're riding offroad.
Nice.
There's also a 46-30 chain set as well,
if you want even slightly easier gears.
Now, good nerd fact to you here,
the 48-31 is actually the biggest spread of gears
that Shimano has ever created in a chain set.
Yeah, I'm great fun at parties.
We've got the GRX brake calipers here.
Although, truth be told, they're physically,
like technically, the same as the Ultegra level calipers.
They're just sort of badged up with the GRX branding
and colorway to make them all match.
But an important detail is that GRX is
hydraulic disc brake only.
Meaning there's no cable actuated discs
or rim brake options available.
Now, to ensure that this is a complete group set,
in addition, we're also giving away
an 11 speed Shimano Ultegra chain.
Two Ultegra level 160 millimeter Ice Tech rotors.
And an Ultegra level 11-34 cassette.
The reason why these are Ultegra and not GRX
is because there aren't any
GRX specific components for these.
And that's because these are designed to work with it
and they're completely compatible.
You can also use Shimano's
mountain bike specific components with this.
It's all cross compatible.
So, for example, if you're using a
one by GRX rear derailleur,
the Shimano mountain bike cassettes
are typically what you would use and you can use, well,
Shimano XT disc brake rotors if you wanted.
Now, for the part you've all been waiting for.
How do I get my hands on this amazing group set?
