New Cadex First Look | Hot Tour de France Tech


– It’s the 2019 Tour de France and I’m in Brussels for the Grand Depart. It’s a hive of activity
here, there’s loads going on. One of the most exciting
things is the launch of a brand new components
brand called Cadex. Now, while at the Grand
Depart, Cadex invited us down to the launch to show
you what it’s all about and check out the new components. (relaxed electronic music) The launch is happening inside here but before I dive in and show
you all the cool techy details of the new products,
remember be sure to subscribe to GCN if you haven’t already
and click the little bell icon as it’ll give you a
notification every time we upload a video, and it
helps support the channel. So it’s all happening down here. Now, Cadex is a new brand
but some of you may remember the Cadex name from around 20 years ago and that’s because Cadex
is a subsidiary of Giant, which is the largest bike
manufacturer in the world. Now initially, the brand is launching some rather tasty wheels, some tires, and also a saddle as well but more products are expected
to join the range later on. And they’ve got them on display on some very tasty bikes down
here, so, going to have a look. Look at this Sarto! Very nice, what a weave on that. Got Olympic champion, Greg Van Avermaet’s glittering
gold custom bike as well. Very nice. First up we’ll take a look at the wheels and there’s a pretty
comprehensive range off the bat. And the wheels are going to be offered in disc brake versions, tubular versions and also tubeless versions
throughout the range. Cadex is looking to position
itself as a premium brand and consequently the wheels and products had a correspondingly large amount of R&D go into them. Now, in contrast, a sort of
lower end wheel manufacturer will typically buy some stock carbon rims from a carbon manufacturer and then some off the
shelf spokes and hubs and build up the wheels and just slap their own
logo on it and sell it. But Cadex has designed
everything from the ground up, all the components. and the rims have been
optimized aerodynamically using CFD, computational fluid dynamics, and also wind tunnel
testing at Magny-Cours. And then real-world
testing with top athletes including the CCC team
and Greg Van Avermaet. And this helps optimize the stiffness and handling of the wheel. This level of R&D, and design
that goes into the wheel is generally what separates
your entry level carbon wheels from, well, more top-end stuff. Road wheels are available in two depths, so we’ve got 65 millimeter ones like these and also 42 millimeter ones. Now, there are also tubular, tubeless, and disk brake wheel options. These 65s, just 1367 grams a pair. But I have to show you the 42s which I’ve spotted over there ’cause they are seriously light. So this is the Cadex 42
tubular seriously light, just 1163 grams a pair that
is properly impressive, that, they are ridiculously light! And that’s impressive for an aero wheel that’s 42 millimeters deep. And also quite interestingly,
the tubeless version which obviously has a
different rim profile, is just around 100 grams
heavier which is just there. The wheels are nice and wide as well, so 19 millimeters internal rim width which is good ’cause it helps
keep the tire nice and wide when it’s seated and stops any mushrooming which compromises aerodynamics when the tire sits
wider on a narrower rim. And something which helps keep the weight of these wheels down is the spokes. Get this, these spokes are carbon fiber and they use something which Cadex calls dynamic balanced lacing,
I’m not entirely sure what that means but they’re
custom for these wheels, and they’re directional. Get this, right? So each one of these
spokes is carefully shaped into a mini aerofoil. It’s hard to see but when
you run your fingers down it you can feel it, so the leading edge is rounded like a little mini plane wing and the trailing edge is sharper so, helps, supposedly, make
a wheel more aerodynamic when the wheel is spinning. That’s properly cool. I actually spoke to some
of the CCC mechanics and riders yesterday, and now they’re sponsored by Cadex wheels they were telling me that they’re actually having
to add some additional weight to the bikes to get
them up to the UCI limit of 6.8 kilograms so we weighed
Greg Van Avermaet’s bike and it came in at 6.5 with the 65s in so, quite interesting,
but I’m a massive TT nerd as many of you know, so
I’m particularly excited to see that they’ve got some
new time-trial wheels here which are over here. Now this is the new Cadex 4-Spoke Aero front time-trial wheel and this
is the new Cadex Aero Disc. Now the eagle-eyed among you may have spotted these
being used by CCC riders earlier in the year during time trials. But they were prototype versions. These are the finished versions
and they are very nice. They’re made of this kind
of tech stream carbon fiber which we’ve seen I think
on some Shiro helmets in the past with this
sort checkered weave. It’s very pretty, isn’t it? Something I’m really pleased to see is that in addition to the tubular version we’ve seen the pros riding,
and that’s what this is, there’s also a tubeless version. It’s slightly heavier but I
love tubeless in time trials because it means you
can run tubeless tires which can often offer
lower rolling resistance, making you faster. These spokes are directional as well so they are like mini wings so you, again, like the actual tiny spokes you’ve got this rounded leading edge trailing off to a wing shape at the back. Very nice. Now the hubs are cool as well, right? So the hubs have been designed by Cadex to be part of this homogeneous system within the wheel and, well,
they sound amazing, right? There’s other people in here but I’m going to do a free hub
soundcheck, check this out. (wheel hub clicking rapidly) How mega does that sound? It sounds like a klaxon, (he laughs) like an air-raid siren! I think the sound’s being amplified ’cause it’s on a disk
wheel and it’s hollow. And one of the reasons for that sound is these low friction hubs that have been installed in these wheels. Now, one of the reasons is
they have a 30 tooth pick up which is great ’cause it
means you get really quick, snappy engagement, and that’s more than a lot of competing hubs. So, the DT Swiss 240 hub for example often has an 18 tooth
ratchet system in there which won’t pick up as quickly. And it’s said that this
30 tooth mechanism in here can also take a higher
load, 30% higher load according to Cadex. Sounds good though, doesn’t it? Nice. As mentioned Cadex also has a new range of tubeless tires which are designed to integrate perfectly with
their tubeless race wheels. So they’ve got the Cadex
Race Tubeless initially and it’s available in three widths so we’ve got 23 millimeters like this one, 25, and then also these
rather chunky 28s as well. And then there’s the saddle. It’s called the Cadex Boost, and you may be able to see, it’s a truncated saddle with a short nose, these kind of shapes are
becoming increasingly popular but Cadex tells me once again, this is just the first of their range and they’re likely to
bring out other shapes in the near future. It’s a very premium product,
as with the other stuff so just 138 grams for this
bad boy and part the reason for that is it’s got a full carbon shell and rail system underneath
so very bling indeed. Now certainly, well, truncated saddles are becoming more popular but
Greg Van Avermaet’s a fan. He appears to have it on all of his bikes. So there you have it, some
tasty new premium products. Now it’ll be really interesting to see what else comes from this ’cause the engineers tell
me it’s only the beginning. Maybe even a disk, disk which
would be particularly cool. So let us know what you
think of a new Cadex range in the comments section down below. And I know what you’re probably thinking, where can I get myself one of those awesome
France themed GCN T-shirts? Well, fortunately,
they’re currently for sale in the GCN shop, so you can get one there. Right, I’m going now, bye!
