hello everyone this is real here from
0:01
singletrack magazine and we're here at
0:03
Eurobike 2018 it's day one and we've got
0:06
a pretty exciting product to show you
0:08
this is a brand new drivetrain from
0:11
Spanish brand rotor now you may know
0:13
rotor more as a crank set and chainring
0:15
brand but in recent years they've
0:17
released a hydraulic group set for road
0:20
bikes this what we have here is a brand
0:23
new group set and this will work on
0:25
mountain bikes in fact I'll work on any
0:26
bike it's designed as modular system it
0:28
is 13 speed drivetrain so according to
0:33
rota this is the world's first 13 speed
0:35
drivetrain now if you thought SRAM Eagle
0:38
was big at 1050 and then you thought
0:39
Shimano XT R was ridiculous at 10:51
0:42
check this out this is a 13 speaker set
0:45
it's 10 to 50 to massive it's a five
0:48
hundred twenty percent gear range so a
0:50
huge 13 speed cassette the thing that
0:52
rotors going to be doing with this one
0:54
by 13 group set is it will be offering
0:56
different cassette options so you won't
0:58
be locked into a particular ratio as you
1:00
can see above here we also have a ten to
1:02
forty six the ratios are as you can
1:05
imagine tighter so if you don't need
1:06
that huge 10 252 cassette you can get a
1:09
smaller one this might be more appealing
1:10
to cross country races and enduro races
1:12
and so on now to fit those 13 sprockets
1:17
onto the hub rotor have developed a
1:19
special freehub standard so this is a
1:22
specific hub that you're required to run
1:24
either these 13 speed cassettes the
1:27
overall hub width is the same as a
1:28
standard hub but the freehub body is
1:31
slightly wider still a Shimano styles
1:33
Shimano hg style but it is wider to fit
1:36
the extra 13
1:38
13th sprocket on there and the hub body
1:41
itself is a little bit narrower so the
1:43
total width is the same this gets a bit
1:45
narrower this gets a bit wider to fit
1:46
that extra cassette that extra struck it
1:49
on there however here's what's rather
1:52
exciting rotor we'll be doing 12 speed
1:54
version as well so we've got a couple of
1:56
cassettes down here we've actually only
1:58
got one on display so this is an 11 to
2:01
52 percent now this will fit on a
2:03
regular mono HD freehub body so you
2:07
don't necessarily need a special freehub
2:08
body to run that big cassette on there
2:10
rotor will be offering both a 13 speed
2:13
and the twelve speed options the
2:15
derailleur and the shifter are the same
2:16
so we've got a neat little trigger
2:18
shifter here and a huge chunky rear MEK
2:21
now as with rotors existing uno group
2:24
set this is hydraulic so there's no gear
2:26
cable in here this is mineral oil that
2:29
gets forced through the shifter into the
2:31
rear derailleur all the indexing happens
2:33
inside here so all the mechanism in here
2:35
that that locks you between each
2:37
different gear that happens inside the
2:39
rear derailleur there is a clutch
2:40
mechanism in here which is provide
2:42
tension on the chain so particularly
2:44
with the one by chain ring to avoid the
2:46
chain from bouncing off and there's also
2:49
another neat feature which is this
2:51
little switch here which is a pulley
2:53
cage unlock so by flicking that open you
2:56
can actually unlock the mechanism and
2:59
that helps you to if you want to remove
3:01
the rear wheel from the bike I'm going
3:02
to show you that on a bike shortly to
3:05
give you a bit of a look you might be
3:06
asking why why 13 speed we already had
3:10
12 speed and that was ridiculous but now
3:12
we've got 13 speed for Roda I guess the
3:15
answer is why not with the 13 speaker
3:19
set they're offering obviously more
3:20
gears but also a tighter spread of years
3:22
as well so they're focusing a lot on the
3:24
ratios with these new cassettes I'm
3:26
going to show you the road and gravel
3:28
cassettes because these are actually
3:29
interchangeable with the rear derailleur
3:31
this rear mech will work with both the
3:34
road and the mountain bike cassettes so
3:36
the road cassettes we've got on here
3:38
started a ten to thirty six ten to
3:40
thirty nine ten to forty six these are
3:43
the 13 speed cassettes there will be 12
3:45
speed versions of these and of note the
3:48
twelve speed version is exactly the same
3:50
it just doesn't have that tentative cog
3:51
that's taken off and then you've got 12
3:53
years on there so that's how they that's
3:55
how they build the cassettes in total I
3:57
think there are eight different cassette
3:58
options so if you wanted to run the ten
4:00
to forty six ten to thirty nine or if
4:02
you wanted to even run the ten to thirty
4:04
six on your mountain bike you could do
4:05
that Rhoda's allowing you to mix and
4:07
match to your heart's content let's take
4:10
a bit of a look at a derailleur on a
4:12
bike here now we don't have a mountain
4:13
bike on display this is obviously an all
4:15
Bay a road bike this give you a bit of a
4:17
closer look at the derailleur mounted
4:18
onto a bike chain here we've got from
4:20
KMC so rotor is working with km
4:23
for the 13 speed chain but here you can
4:26
see how chunky this rear mech is looks
4:29
very very nicely machined I should note
4:32
all of the components are made in Spain
4:33
this is a Spanish made group set as they
4:36
make the cassettes in-house the
4:38
derailers in-house these are all made in
4:40
Spain so here I'm going to show you the
4:43
little pulley unlock system this is a
4:45
little button here that I'm gonna I'm
4:47
gonna press in and it basically releases
4:49
the chain so you've got a bit more chain
4:51
link there in order to pull the rear
4:53
wheel out and then if I push this back
4:56
across clips in place and then you're
4:59
back on for riding so that's how that
5:01
little mechanism there works if you're
5:03
getting close on the derailleur you'll
5:04
be able to see the little bleed port
5:06
here so you use a standard syringe
5:08
system to bleed it just like you would
5:10
with mineral oil disc brake so it's
5:13
basically exactly the same the idea with
5:16
the hydraulic system provides a really
5:18
light lever feel and in theory because
5:20
it's sealed from top to bottom it should
5:23
be nice and durable against
5:24
contamination from water and dirt and
5:26
mud and so on so that's the theory
5:28
anyway
5:29
now this is all very new it's still in
5:31
prototype development rotor is planning
5:33
to have this group set due in the first
5:35
quarter 2019 so we're still a while away
5:37
before we'll see this in the flesh
5:39
before we get one in for testing but
5:41
that's a bit of a first look at a 13
5:43
speed group set and that cassette we
5:45
showed you before that 10 to 52 cassette
5:47
from Spanish brand rotor this is will
5:50
reporting from Euro bike 2018 thanks
5:52
guys hope you enjoyed stay tuned for
5:54
more bye
