Team Sunweb’s 2019 Cervélo S5 Aero Race Bike | Joris Nieuwenhuis’ Pro Bike

– This is the new Cervelo S5
Disc of Team Sunweb Cervelo, replacing the previous
sponsor Giant for 2019 and let’s have a look at
the bike, which is probably the most strikingly
different in the complete world tour selection. (deep bass music) So the frame has actually
taken a complete redesign and overhaul compared to its predecessor, although at first look
it may not look like that and strikingly, most people
actually at first glance think that the bike looks
really high at the front end because of the upward sloping stem, but in actual fact the bike
has got longer and lower than before thanks to feedback
from professional riders. So if we look at the
down-tube of the frame, you can see there’s a cut-out
where the front wheel goes, and that’s in order to
get that front wheel just a little bit closer to the tubing, to optimize the airflow,
and while the seat tube still has that cut-out
for the rear wheel too, but it has got a little bit
slimmer, as has the actual tubing profile of it and the
seat-post therefore has got a little bit narrower too,
okay let’s move on then to the front end of the bike,
because that is radically different from the previous model. Firstly we’ve got an
external steerer tube, because normally a
forked steerer tube runs inside of the head-tube, but in this case by doing that they can actually
have a narrower head-tube, therefore more aerodynamic and also apparently it’s 13% stiffer too. Now many people out there will actually wonder how on earth you would set the headset preload tension. Well there’s actually a
rod which runs here from the back if the fork-crown
up and into the head-tube, where it actually meets the
top-tube and it’s set that way. It’s nicely hidden away actually. Now what about the
handlebar and stem then, because this is where it’s
totally different again from any other bike we are
seeing in the world tour. It’s a Y-shaped affair and it is in fact a two-piece setup which means
that customization is gonna to be a lot easier that a
one-piece integrated unit because you can have
different length stems from 90 millimeters to 130,
and also bars from 38 to 42. Now if that’s not enough
for customization you can also rotate the bars
slightly so you can have them in 0 degrees, 2 1/2
degrees and 5 degrees too, through some clever shims
and arrangements here where they mount into the
stem, and if that’s not enough for customization, why not
change your headset spacers too. So with all the refinements
in aerodynamics on this bike, including fully internally routed cables, the savings are 5 1/2 watts at
40 km/h, but at the same time they’ve also focused on stiffness too, and I’ve already mentioned
that the head tube is 13% stiffer and that bottom bracket well, that is big and chunky
and this is gonna be music to every sprinter on the team’s ears, it’s 25% stiffer than before, 25%. Now if aerodynamics are
really your thing and you don’t get that thirsty out riding, well you can actually move the
bottle cage on the down-tube to a different position,
so slightly further towards the bottom bracket,
of course yhat means you won’t be able to use
the other bottle cage but, apparently according to their tests that will make it
slightly more aerodynamic. Now the bike is actually only
available for disc-brakes, so those diehard rim brake
lovers of you, if you want one, you’re gonna to have to
make the change I’m afraid. The groupset Shimano Dura-Ace 9170 which is of course their
disc-brake groupset and is electronically controlled gears. Speaking about the gearings
then it’s the pretty much pro standard 53-39 chain
rings, 11-28 cassette, and this bike in particular
belongs to Joris Nieuwenhuis and it’s got 175 millimeter
length cranks on it. Now the power meter
that comes from Shimano and it’s the R9100P
which is dual-sided and in order for it to fit
inside the oversized BB right bottom bracket
shell, there is a rotor cup placed in position to accommodate that. The wheels come from Shimano
and fitted onto Joris’s bike right now are the C60s but
of course that can change depending on the weather
conditions and also the rider weight and their style and also just their
individual preferences. Tires, they’re Continental Pro Limited and 25 millimeters and apparently the bike can accommodate up to
30 mil, but it’s gonna to be pretty close because the
clearances aren’t that big. Now finishing touches
include Pro handlebar tape, a Sigma Rox computer which
is secured as well with a lanyard there, so in the
event of a crash you’re not gonna lose it, the Di2
junction box is really neatly inside of the handlebar end plug there, it’s one of my favorite
little bits you can do and also saddles are from
Pro and of course that’s a rider’s choice, bottle
cages they come from Elite and these ones are the
Custom Race Plus model. Now sadly I don’t actually
know Joris’s height, I haven’t been able to measure
him yet, but he does ride a size-56 centimeter bike but his saddle to center of bottom
bracket measurement, well the distance there is 78
centimeters, and tip of the saddle to the center of the bars
is a whopping 60 centimeters and his saddle to bar
drop is 11 centimeters. Right, time for the free-hub sound-check Shimano Dura-Ace 9170
hub, let’s have a listen. (wheel clicks) And the weight of it, including a couple of empty water bottles, 7.93 kilos. So there we are, the Cervelo S5 Disc of Joris Nieuwenhuis and
Team Sunweb for 2019. Let me know what you think
of it in the comments section below because I think the
external steerer tube and the Y-shaped handlebars are gonna create a bit of a debate. Don’t forget too, to

click on the saddle and, well me, I’m gonna take
a sit on the saddle. All the best.
