New Wilier Zero SLR | Lightweight Aero Bike First Look

– We have got a very exciting
first look for you here today. This is the brand new Wilier Zero SLR. (upbeat electronic music) Now, Wilier is one of the most historic and recognizable bike brands in the world. This is its first super lightweight bike with disc brakes and
fully concealed cables. In case you aren’t familiar with Wilier’s enviable
heritage in cycling, it’s one of the oldest bike brands in the world, dating back to 1906. And it has had formidable
success in professional cycling having even been ridden by some of the greatest climbers of all time, including Fiorenzo Magni, Marco Pantani, Damiano Cunego, and Michele Scarponi. And in recent years, the
climbers have tended to favor Wilier’s superlight series of Zero bikes. And the Zero SLR is the
latest model in that range, replacing the previous
deranged topping, Zero7. It used to be, when choosing a new bike, you have to make a choice, a compromise. Either lightweight or aerodynamic. But now, according to Wilier, you can have both. (heavy bass electronic music) First up, being a Zero series bike, you’d expect it to be light, and it is. It’s very light. Wilier claims that it’s just 780 grams in this size, which for a disc brake equipped bike, is very impressive indeed. And the fork is also light. They claim it’s just 340 grams, which again, is impressive
especially when you consider it’s been beefed up to cope
with the asymmetric forces from disc brakes being
just mounted on one side. You can actually see, if
you look straight down, it’s noticeably thicker
on this right hand side. But it’s not all about
lightweight for Wilier. Super lightweight bikes can
often feel a bit noodly, not the stiffest machines in the world, and with the new Zero SLR, Wilier claims to have the
highest stiffness to weight that it’s achieved so far. In fact, it’s supposed to be 24% stiffer than the previous Zero7 model. One of the ways Wilier
says it’s achieved this is by using a new type of
carbon fiber called HuSmart, which they claim is qualitatively superior to any kind of carbon
that they’ve used before. They’ve also employed a
liquid crystal polymer in the carbon as well, and this is said to reduce vibrations and improve impact resistance. This is cool, too. Take a look at this. The new bike has a completely new designed seat post clamp design. It’s all hidden and integrated
to keep out of the wind, but it also makes it look really neat. So, you’ve actually got the collar hidden inside the frame here, and it’s accessed by a little bolt there. You also got a D-shaped seat post, which has become a common feature on lightweight aero bikes as it offers greater compliance. It’s able to flex ’cause
it’s flat at the back, but also, it’s a slightly
more aerodynamic shape with this sort of Kamm tail profile. With regards to other aero
features on the frame, there are truncated tube
profiles and Kamm profiles featured in various locations, which have slightly lower
drag than just round tubes. And also the fork blades,
you may have noticed, are slightly spaced further
apart from the wheel than you find on other bikes. This is a feature that was first seen on Wilier’s Turbine TT bike, but we’ve also seen it on other bikes such as the British cycling track bikes that you may have seen in the Olympics. The Zero SLR has a proprietary,
integrated cockpit. Now, the Cento10, Wilier’s aero bike, also has an integrated bar and stem, but this one’s a completely new design. And as you can see, or
well, maybe you can’t see all the cables are completely hidden. They route through the
bar, through the stem, and then down into the head tube. And to make life easier with this, it’s good to see, the spaces split in two
which means that if you want to adjust your stem and
make it higher or lower, or add in or take out spaces, you can do so relatively
easily without having to disconnect the brake lines, which being hydraulic brakes, well, is a blessing and
is a feature that plagued some of the earlier heavily
integrated bike designs. I should also point out that the bar is said to be really light as well. Really, it claims that it’s just 330 grams for a 100 millimeter stem
and 42 centimeter wide bar. And at the back, we’ve got
the dropped seat stays, something which has
become a defining feature of modern aero bikes. The reason why bike brands
are increasingly adopting it is because it’s said to be more compliant, because the idea is that you get a longer effective seat tube which can flex a bit more. And they’re also said to offer
slightly lower drag as well. And you may notice that here, we’ve got a very asymmetric design. And this is to cope with
the differing forces. So, you’ve got the drivetrain
load forces on the right side and the braking forces from
the disc on the left side. Now, you may be wondering what are these rather bling carbon wheels we’ve got on the bike. Well, these are ULT38 KT disc wheels made by Wilier. And they’re one of three wheel sets that Wilier’s going to
be offering in 2020. And they’ve been in collaboration with the wheel brand Mische. Interestingly, all three wheel
sets will only be available as a disc brake model. Clearly, Wilier’s designers
have been paying attention to the rim brake extinction
clock in the GCN Tech show. Also, being Wilier’s
thoroughbred race wheels, they’re only available in
tubular versions as well. So, these are tubular wheels
we’ve got on right now. And something else nice is that the bearings in them are CeramicSpeed, so, a few extra efficiency savings there. So, these, the ULT38s are actually 37.8 millimeters deep, not quite 38, but they weigh
just 1,390 grams a pair, which is nice and light. And I’m going to do a freehub soundcheck. (freehub buzzing) CeramicSpeed for you. Nice and smooth, look at that. Connecting the wheels to the frame are Mavic’s speed release thru-axles, and these are a special kind of thru-axle that allow you to remove
the wheel from the frame without entirely removing
the thru-axle from the wheel. It may not much to amateur riders, but for a pro cyclist trying
to save every last second, then, well, a quick wheel
change could be the difference between winning and losing. Being a top of the range bike, we’ve got top-sec components throughout. So, we’ve got four Dura-Ace Di2 including a compact 50/34
chainset and an 11-28 cassette. Now, I know what some
of you are going to say. Why has an Italian thoroughbred super bike not gotten Italian groupset on it? Well, don’t shoot me,
I’m only the messenger. But it does have some
Italian components on it. We’ve got Vittoria corsa
speed tubulars, very nice. And a Selle Italia SLR saddle. And that’s it, really. With Wilier supplying, well,
the cockpit, the seat post, the fork, and the wheels, it’s kind of a trend
we’re increasingly seeing with bike brands offering
greater system integration by doing more of the components themselves thanks to a world specialized Roval and trek with Bontrager. All right, I think it’s
time we weighed it. Feels light, this. Place your bets now what
you think it’s going to be. 7.1, that is impressive
for this great bike. I hope you enjoyed this
first look at what is, oh, I think, a really beautiful bike. And if you have, then
