GRX RX800 Di2 group set. A whole group set! How awesome is that? I mean, unfortunately,
I’m not allowed to enter. But one very lucky viewer will
win this complete group set. Now, before I go into

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
