The Most Aero Bike Ever? | Aerodynamic Cycling Tech From Eurobike 2019


(electronic whooshing) – I’m still at Eurobike and myself and Jon are on the lookout for the most aerodynamic tech that there is at this year’s show, and before we show you
all the amazing stuff that we’ve found, make sure you subscribe to GCN Tech and click the bell icon so that you get notifications. And if you’re wondering what this is, well, it’s called the Alpha 7. It’s a aero-faired
recumbent from Velomobile, and it’s absolutely incredible. I’m told you can easily hit
speeds of 60 kilometers an hour on the flat on this, whereas
if you’re riding a normal bike, that would be equivalent to riding about 30 kilometers an hour. It is an incredible machine! (laughs) Just start inside here, you’ve
got two wheels at the front, one wheel at the back. I really want to go in one
of these, they’re amazing. – Now I’m here with a bike
which Specialized have said is the most aerodynamic road
bike they have ever tested. So CeramicSpeed, who
of course have produced the Driven drivetrain system, partnered up with Specialized
to undergo a load of tests, and they compared it alongside a bike of almost identical structure to this one, but of course it was fitted with a standard 53/39-tooth
drivetrain on it, and with a normal rear derailleur. Now, the end of the tests,
which were quite lengthy, showed that the average
saving using this bike, compared to the standard
bike, was 3% more aerodynamic across all your angles, which equated to roughly
an eight-second saving over 40 kilometers. Now, the way in which they’ve got it to be even more aerodynamic
is by using this fairing, or this drivetrain cover here, of course that’s going to keep
it nice and clean in there too, and out of harm’s way, if you like. But that is a big statement to be made. The fastest road bike they’ve ever tested. Just over my shoulder,
I’ve got Peter riding on the Bioracer speed sensor concept. Now what this does, it
essentially takes a snapshot of your riding position, and from then on, it can calculate the frontal area, and you can hone your
position in, and believe me, check out those watts that he can save. I mean, right now, he’s going up and down, you can obviously see he’s
moving around on that bike, but I have seen him save 140 watts just by getting his frontal
area just a little bit smaller. This sort of thing is absolutely great, and I reckon riders are
going to be using this more and more. Factored in as well is the fact that you can calculate your
angles from it as well, so, sorry, you can hone your
position in around your angles, so something like the hour record, this thing could work oh so well. Because, get this, I’ve been
told it can even calculate the differences at altitude too. Oh, yeah. – I’m over out on the Shimano
stand, and I’ve seen something that looks, well, aero, but it
is also absolutely stunning. Absolutely mega. Check this out. This is the Shimano Pro
Vibe Aero Handlebar, it’s been around a while
now, but it’s got lighter, they’ve updated it, 195 grams now, then it’s called the Superlight. But something completely brand new is the new Pro Vibe carbon stem. Check this out. This thing looks absolutely incredible, it’s designed to work with that aero bar and Shimano’s other bars, it’s said to have an
aerodynamically optimized design. But Shimano has tended to
shy away from carbon stems in the past, favored
stronger, stiffer ones made from aluminium and steel, but yeah, that thing looks absolutely incredible. It’s said to weigh just 120
grams too, so pretty light, but this clamping mechanism
is absolutely fascinating. The stem is available in lengths
from 80 to 130 millimeters, and the bar is available in
widths from 38 centimeters wide, which is my preference, up to 42. And something else I
really like on this display that probably needs a bit of attention is this really, really,
really, really stunning pro bar tape. It’s like in this iridescent
green color, and it’s nice, it just looks really cool. (laughs) It’s just really nice. – When it comes to aero
stuff, I always think about the Look time trial
bikes that Answer used back in the ’90s. They had some really
wild and wacky designs. And one of the great products back then was the Look Ergostem, and the
new Ergo extensions from Look appear to basically have
taken some inspiration from that stem, because that
stem was highly versatile, highly adjustable, and
these little end bits here, on the end of the Ergo extensions, are actually held in
place with a Torx screw that you can loosen and tighten, and you can then adjust them
to your heart’s content, so you’re nice and comfortable. I love that. If that’s not enough though,
because let’s face it, not everybody can ride
in the exact position the bars are made in, you can then peel back the forearm pad, and underneath there you’ve
got a couple more screws that go into the carbon extension, and then you can shorten and lengthen it, and if that’s not enough, the
forearm angle can be adjusted up to 20 degrees. – Eddy Merckx has launched a
brand-new flagship race bike, here, you’re by it, this is the 525, and it ticks all the boxes for
new bikes we’ve seen in 2019, so it’s slightly aero, it’s lightweight, it’s got
disc brakes, dropped seatstays, more integration, you get the idea. But I think it looks rather
cool, and it’s going to be ridden by the AG2R team in 2020, so you can actually get
it in AG2R team colors when it’s available to buy, and if you recognize the cockpit, that’s because it’s from the
Ridley Noah Fast aero bike, it’s the same design,
with the split spaces and all the neat cable integration. And in this build, the
bike is set to weigh around seven kilograms,
which is pretty competitive for a disc brake road bike
with clincher wheels on it. Nice, and over there I’ve just spotted Oliver Naesen’s steel bike
that he rode in the final stage of the Tour de France. What are we saying for this,
nice or super nice? Whoo! – Right, you don’t get much more aero than an aero helmet, do you? And let’s face it, the
one of Victor Campenaerts when he broke the world hour
record earlier on this year is the HJC Adwatt helmet. Now, this helmet has been
designed to be aerodynamic both with and without a visor. And having worked in the
helmet industry before, I know the importance of
aerodynamics, obviously, when it comes to developing
a TT helmet, and, especially, this one doesn’t have a
particularly long tail to it. When you’re riding on
the track, generally, riders do tend to go for something with a slightly longer tail, which means his position
is probably optimized around using a shorter helmet. I know I’m getting into quite
a bit of details here too, but the fact that he
never races with a visor always leaves my head scratching. But the fact they developed it both with and without the visor, and
there’s aerodynamic gains to be made, leaves me with
a happy smile on my face, and, well, hopefully Victor
doesn’t get any flies in his eyes. – Who doesn’t love carbon wheels? Well, fortunately, at the Vision stand, they’ve got some new ones. These are the new Vision
SC’s, and the idea is that they fit in between the
entry-level TriMax wheels, which are here, and the
top-of-the-range Metron wheels, so they’re designed to
offer similar performance to the Metrons, but in a much
more affordable price point. And they do this by having
a slightly lower-spec hub, with lower-spec internals in there. We shouldn’t compromise
performance too much, but just offer excellent value, but they certainly look the business. Although these are
intended to be mid-range, the weight’s competitive with the much more expensive Metrons. According to this slide here, it says they’re 1500 grams a pair for this 55-millimeter-deep
set that are tubeless ready, which is, what, it’s really competitive. – Now if you want to go full-on
aero, even on a road bike or on a time trial bike, doesn’t matter, then what about the
Vision Metron TT crankset? Just check it out. It’s a monocoque carbon
fiber construction, and the way it fills in
that chainring is so good. Now, there is one downside,
I’ve got to say actually, about this one, is the fact that the chainring
is bonded into the carbon, if you like, so if you
were to wear it out, you are going to have to
get a whole new chainset, but the chances of actually
wearing that out is so slim, because nobody rides a time
trial bike that much, do they? I don’t know, but the inner
ring is totally replaceable. Now, the crank links come
in from 165 millimeters, all the way up to 180 millimeters, which is pretty fine indeed, and it comes with a BB386EVO axle, so it’s going to work with
most modern frames out there. What the folks at Satori
and Acros have done, well, Acros, by the
way, are a manufacturer of various different
components, including headsets, very specific ones, quite often, with kind of little grub screws and all sorts of things like that, right, anyway, enough about this, because what they’ve done here is actually integrated into a
headset spacer an open port, if you like, so you can root
your cables or hoses in there, provided, of course,
that you’ve got the room around the actual fork,
steerer, and everything, and then your cables could
go down inside the head tube and run internally all the way down. I love things like this because
it’s such a simple idea, and really well-executed. Why didn’t anyone think of this before? – I hope you’ve enjoyed this
