Want to learn how to swapout the CTS unit on your Formula shock? It's a lot easier than you think.
Formula's rear shock has been seen on the rear of Joe Barnes' Orange for the past few months, and fans of eMTB's might have seen the Mod coil shock on the new Sunn range of eBikes. But it's only today that the shock has been officially revealed and we can release all the juicy details.

what we're gonna do is the full
0:03
uh like rider experience
0:07
because have you ever seen this shock
0:09
before not before today
0:11
okay have you ever changed cts are you
0:13
familiar with cts technology maybe into
0:16
so that's the perfect testing brand new
0:19
okay
0:20
so we will follow the steps that are the
0:22
same
0:23
that the riders will find in the owner's
0:26
manual
0:27
okay okay first remove the shock from
0:30
the bicycle
0:31
done done okay that's a good mechanic
0:34
okay and do not unscrew the spring
0:38
done perfect okay second
0:41
turn the lockout lever to the closed
0:44
position
0:45
okay perfect unscrew
0:48
the reservoir's cup
0:54
now using a shock pump that can be any
0:57
shock
0:58
pump remove all the air
1:01
from the reservoirs this is
1:04
very important you have to do different
1:06
times to be sure
1:08
there is like no hair now
1:11
you can remove the shock pump and then
1:14
you can screw
1:16
the reservoir cap back in
1:20
back on back on okay done done
1:24
now position the shock on the vise with
1:27
the compression
1:28
knob in upward position
1:31
you don't need to over tight too much
1:33
because just to like having the shock
1:35
exactly
1:35
exactly turn the compression knob in the
1:39
fully
1:39
open position
1:46
using a t10 torque torx tool
1:50
remove the screw from the compression
1:53
knob
1:56
here we go using a
1:59
13 millimeter socket wrench this
2:03
guy here unscrew the cts from the shock
2:06
of the body by doing this
2:09
use a paper towel because a little bit
2:11
of
2:12
oil mail drops may drop so
2:15
what we suggest is like you can tell
2:18
you can take like a paper like this
2:21
so nice and clean
2:25
here we go
2:33
now you can remove the cts
2:37
one thing there is a okay perfect
2:41
it's done everywhere no it's okay
2:43
perfect
2:44
this is our suspension not suspension
2:47
oil this is not the same of the fork
2:48
this is specific for the shock
2:51
by just using a bleeding syringe
2:54
put two cc of oil
2:58
back into the shock
3:08
so two is a little bit more than what
3:11
you really
3:12
uh needs at this point but we suggest
3:16
to do a little bit more and then if the
3:20
some oil drops out while you're
3:22
inserting there is no problem
3:23
at all but then you are 100 sure that
3:26
you have the exact amount of oil that
3:28
you need on the shock so
3:30
at this stage you're good to go
3:32
absolutely
3:33
so now choose cts what you want the gold
3:37
the orange the orange is the standard
3:40
one
3:40
let's say the medium then the gold is
3:43
the softer and the green that
3:45
we just remove is the the firmer one
3:48
gold gold so now
3:52
insert the desired cts by pushing it
3:55
inside the shock body at this point
3:57
push until the o-ring of the piston goes
4:01
into position by doing this use a paper
4:04
towel because a little bit of oil mail
4:06
drops
4:07
so this is the thing that it can be a
4:10
little bit tricky at the beginning
4:11
because you have the
4:13
the oil the sorry the o-ring you don't
4:16
know because you never did before
4:18
how much pressure you need so if it's
4:20
the very first time you may go very
4:22
gently
4:23
or and you need a little bit more so it
4:26
can be
4:27
let's say at at least for the first time
4:29
tricky but right
4:30
yeah you need to hear a click
4:33
here we go and then push it until
4:39
here we go now with the
4:42
socket wrench
4:48
screw the cts back in applying
4:52
7 newton meter but
4:57
you can also not use we seven newton
4:59
meter is
5:00
just means is like when you feel that
5:02
the thread is at the end
5:04
stop wrenching
5:08
reinsert the compression knob and then
5:11
reinsert the screw on the compression
5:13
knob by using a torx
5:15
t10 tool which is this one now that is a
5:18
new cts
5:19
you are not sure that is fully open in
5:22
compression
5:23
because it's a new one you open the
5:25
other one
5:26
so and because then you have to reinsert
5:29
the pressure
5:30
you and you want to do it with a fully
5:32
open position so
5:33
now you have to be sure that this cts
5:37
is in full open position in compression
5:39
so
5:40
going towards minus again
5:43
all the way down in this case it was
5:45
already
5:46
in the yeah and i don't need to touch
5:48
this thing no no no
5:51
at this point you can turn the lockout
5:53
on
5:55
yeah sorry on off sorry yeah
5:59
unlock and uh unscrew the reservoir
6:03
reservoir cup again
6:10
with the shock pump put
6:13
95 psi in it
6:16
the shock is made to operate at 95.
6:19
perfect
6:22
and now you can screw the cap of the
6:25
reservoirs
6:26
reservoirs back in and it's done
6:30
you change the shim stack have you ever
6:33
changed a shim stack of a shock
6:35
before no not before now do you have you
6:38
actually
6:39
oh have you actually saw a shim stack
6:42
slice like never you don't have it
6:44
okay but you did it on this one oh
6:47
what's that do it again without
6:49
instructions so
6:50
it must be easy very easy yeah so
6:53
the good thing of the cts that we're
6:55
using on the shock
6:57
is that compared to the one that we are
7:00
using on the fork
7:01
you don't need a special tool uh
7:04
it's just standard tool that everyone
7:06
has in his workshop
7:08
uh the the little disadvantage is
7:12
that you have to take the shock off the
7:15
bike
7:16
that's the only thing that you have to
7:17
do
7:20
i'm pleased with that yeah
