DT Swiss has just launched its biggest, baddest and longest fork ever, and it's called the F 535 One. Designed to go head-to-head with the RockShox Pike, the new DT fork features a cunning spring design to help smooth things out, as well as a unique position-sensitive compression damper.

everyone this is real here from
0:01
singletrack magazine we're here at
0:03
Eurobike 2018 in the DT Swiss booth and
0:06
we've got a brand new suspension fork
0:08
from DT Swiss now this was released only
0:10
a couple of days ago when we first found
0:12
out about this is the first time we've
0:13
seen one in the flesh so we wanted to
0:15
give you a bit of a run through the
0:16
details on this brand new fork from DT
0:19
so long as travel fork the DT has ever
0:21
done it's called the F five three five
0:23
one now it's got thirty five millimeter
0:26
diameter stanchions you're looking
0:28
between 130 to 160 millimeters of
0:31
traveled and there's also twenty-seven
0:33
point five and 29 inch versions
0:34
available this is kind of designed to
0:36
take on the likes or the Fox 34 / 36 the
0:40
RockShox pike so this is what the 535
0:43
one is going after now there's some
0:46
pretty cool features in this fork will
0:48
give you a bit of a closer look for a
0:50
start the design is absolutely beautiful
0:52
it's all about keeping everything really
0:55
clean really tidy so on the top of the
0:57
fork up here we've got nice bolt on port
1:00
covers which actually hide the adjusters
1:02
and the air valve so this side has got
1:04
the air spring and this side has the
1:06
damper you can't really tell because
1:08
you've got this neat kind of integrated
1:10
crown which kind of looks like it's off
1:12
the Batmobile or something the the same
1:15
kind of design aesthetic extends to the
1:17
lowest so on both sides of the four
1:19
clothes we've got little port covers
1:20
here which just kind of tidy everything
1:22
up
1:23
these are magnesium one-piece lowers and
1:26
they've got really nice kind of external
1:28
kind of shaping to give them a good
1:29
amount of stiffness what else have we
1:33
got here oh I should show you if you
1:34
want to come around this side actually
1:36
this is the little quick-release lever
1:39
so you've got your boost
1:41
110 by 15 millimeter thru-axle now if I
1:44
can get this off this actually hides an
1:47
integrated tool so unthread this little
1:51
guy here there's your tiny little talk
1:53
ski now that guy there that's for
1:56
undoing the port cover so you can
1:57
actually take that off here I'll do this
1:59
now and show you what's lurking within
2:03
because you've got extra adjustability
2:05
inside the fork you can adjust
2:07
compression damping and you use this
2:09
little taut key to do that so you can
2:11
actually use that just by hand you don't
2:12
need anything else on top of that and
2:14
you can adjust the the compression
2:16
damping so that's really really neat and
2:18
then just thread that back in there and
2:23
this will you hear the satisfying noise
2:27
yeah oh yeah that's that's a really good
2:30
noise I like that they're just a nice
2:32
little feature DTF of course had the RDS
2:36
skewer on for rear through axles and
2:37
also their existing Forks for a while
2:39
that's a new little feature with the tox
2:41
key now inside the fork there's lots of
2:43
other wizardry going on let's talk about
2:45
the spring first because this is quite
2:47
interesting I've got a set of uppers
2:49
here that we're gonna have a bit of a
2:50
look so as I said thirty five millimeter
2:52
diameter stanchions this is an air
2:54
spring so we're inside you've got two
2:57
air chambers you've got air positive and
2:59
negative so far so normal at the end of
3:02
the spring however this is where things
3:05
get a little bit different inside here
3:07
and if you can see that there's a tiny
3:08
coil spring now that's the steel coil
3:11
spring in there so I'm going to
3:12
demonstrate what that does
3:22
so this this spring design DT Swiss
3:26
collet coil pair basically this little
3:27
coil spring instantly starts working as
3:30
soon as you push down on the fork gives
3:31
it a really plush and kind of really
3:33
smooth immediate starting stroke the
3:36
coil works in tandem with the air spring
3:37
but the coil will only work for the
3:39
first 30 percent of travel or so so it's
3:42
designed to give you that really supple
3:44
smooth starting stroke the perhaps
3:46
sometimes you can't always get with an
3:48
air spring so that little coil helper
3:50
spring that's what I like to call it is
3:52
in there for exactly that reason just to
3:53
get the suspension moving nice and
3:55
smoothly to begin with
3:57
inside the damper here as well we've got
3:59
more trickery this model here we've got
4:01
the crown adjust damping system so this
4:04
is a three position compression damper
4:06
you've got open drive and also lock
4:09
settings so those are three positions
4:11
you can choose from on the fly you can
4:13
either adjust with this model here on
4:15
the crown DT Swiss will also be offering
4:18
a remote adjustable version too and
4:20
there's that little compression adjuster
4:22
which you can adjust with the tox key
4:24
however DT Swiss say this fork performs
4:26
so well but they think you should run it
4:28
with zero compression damping up the top
4:30
there now the reason they think it
4:32
performs so well is it's got position
4:34
sensitive compression damping now I'm
4:36
going to get a little bit more technical
4:37
here this is quite unique for a
4:40
suspension fork the compression damping
4:42
is essentially open for the first 30
4:45
percent of the travel and this is done
4:47
via a valve called the plush port that
4:49
valve is essentially open for the first
4:51
30 percent of the travel but as you get
4:53
towards a SAG point towards 30 percent
4:55
that valve begins to close through the
4:57
next 20 percent so up to 50 percent of
4:59
the travel that valve gets smaller and
5:01
smaller so the oil flow restricts and it
5:03
then pushes the oil through the high
5:06
speed damping circuit so the idea is
5:08
that first 30 percent up to 50 percent
5:10
of the travel has quite a light feel for
5:12
the damping so it's really smooth really
5:14
plush really buttery and then once you
5:16
get deeper into the stroke past 50
5:18
percent you're basically relying on the
5:20
dampers high-speed circuit which is a
5:22
lot firmer a lot more supported so that
5:24
is called plush port that's inside there
5:26
that is position sensitive damping which
5:28
is pretty neat and it's what DT Swiss
5:31
believes makes this fork amongst other
5:33
features so very good
5:36
so that's a bit of a look at the f5
5:38
three five one this is a new fork for DT
5:40
Swiss as I said twenty seven point five
5:42
and twenty nine inch options travel
5:44
between 130 to 160 millimeters and I
5:47
think you'll agree it's a rather dashing
5:49
looking fork we haven't had any ride
5:51
time on this we will be hopefully
5:52
getting one in for testing soon so we'll
5:54
let you know how it performs if you want
