TORQUE ARM INSTALLATION
NOTE !
2.1: Align the torque arm with the
flat face outwards, as shown.
2.3: Lightly grease the end cap
press fit surface.
2.4: Gently tap the match cap in
place with a rubber mallet.
NOTE !
The XIV torque arms must be oriented
with the flat face outwards, as shown.
The XIV torque arm may have a slight press fit
that will require a rubber mallet for installation.
2.2: Gently tap the torque arm in
place with a rubber mallet.

TORQUE ARM REMOVAL
CAUTION !
Make sure to protect the hub shift cam
when removing the match cap, by
temporarily installing the HYSEQ actuator.
NOTE !
The XIV torque arm may have a slight press fit
that will require a two-jaw bearing extractor
tool for removal.
3.1: Insert the match cap
removal tool.
3.2 Tighten the 13 mm
and 17 mm nuts to secure
the match cap tool.
3.3: To protect the shift cam from
accidental damage, insert the
HYSEQ actuator on the drive side.
3.6: Remove the torque arm.
3.4: Slide a thru axle or suitable
punch through the hub from the
drive side.
3.5: Gently tap the axle or punch
to remove the match cap.
3.7: If the torque arm press fit is
too tight to be removed by hand,
use a two-jaw bearing extractor
tool as shown for removal.

GEAR RATIO SPECIFICATION
•The XIV has 543% range and even 13.9% gear
steps.
•For non-assisted bikes we recommend optimizing
the gear ratio according to the intented use case
and rider preferences.
•For most e-bikes we recommend optimizing the
gear ratio to have a comfortable cadence in 10th
gear (0.88) at 25km/h.
•Gates Carbon Drive Calculator: Link
NOTE!
The minimum sprocket ratio of the XIV is
1.9. The minimum front chainring is 32T
on E-bike and 30T on a non-assisted
bike. Using a lower sprocket ratio or
front chainring will void the hub
warranty.
The sprocket ratio is determined as
follows:
12
CHAIN SPROCKET INSTALLATION
CAUTION !
Using a sprocket with a thickness > 2.3 mm or a
non-original lockring may cause the lockring to
contact the actuator, damaging the hub.
NOTE !
The XIV is compatible with 9, 10 or 11
speed chains. Wider chains may contact
the HYSEQ actuator and cause damage.
4.1: Install sprocket. 4.2: Install the hub sprocket
lockring by rotating clockwise.
4.4: Verify that the HYSEQ actuator has clearance
to the lockring and that there is not gap to the
input shaft. The sprocket should rotate freely
when the actuator is installed.
4.3: Torque the lockring to 30
Nm.
Clearance
No gap
13
BELT SPROCKET INSTALLATION
NOTE !
The maximum thickness of the hub
sprocket is 2.3 mm
NOTE !
The Kindernay XIV is compatible with offset
Gates HG HMN sprockets, such as the
CT1122HMN. The belt line is 45.5 mm.
.
5.1: Install sprocket. 5.2: Install the hub sprocket
lockring by rotating clockwise.
5.4: Verify that the HYSEQ actuator has
clearance to the lockring. The sprocket
should rotate freely when the actuator
is installed.
5.3: Torque the lockring to 30
Nm.
CAUTION !
Using a sprocket with a thickness > 2.3 mm or a
non-original lockring may cause the lockring to
contact the actuator, damaging the hub.
14
SPROCKET REMOVAL
NOTE !
NOTE !
If attempting to remove a Gates belt sprocket, a
Gates Strap Wrench is recommended
(https://www.gatescarbondrive.com/products/tools).
6.1: Align the chain whip / belt strap
wrench and lockring tool as shown. 6.2: Loosen the lockring. 6.3: Remove the lockring by
rotating counterclockwise.
PM TORQUE RETAINER INSTALLATION
15
7.1: Apply Loctite 243 to the
torque retainer bolts and
brake caliper bolts.
7.2: Install the torque
retainer with the bolts as
shown.
7.3: Torque to 9 Nm.
7.6: Torque the caliper bolts
to 9 Nm or manufacturer
specifications.
NOTE !
The torque retainer will offset the braking caliper
inwards. For Boost 148 mm frames, the Boost-specific
retainer must be used to get the correct offset.
7.5: Install the hub and
align the brake caliper.
NOTE !
Only Kindernay 7-bolt rotors are
compatible. The torque retainer will add 13
mm to the original frame rotor size.
7.4: Install the brake caliper
according to manufacturer
specifications.
HYSEQ INSTALLATION
16
NOTE !
For hose cutting and bleeding procedures, please see the
manual on https://kindernay.com/support/support-portal/.
8.1 –First mounting point
When mounting the hose to the frame in the first point after the actuator,
make sure there is enough cable length between the point and the actuator, so
the wheel can be pulled out of the frame. Use a rubber band and zip tie to
secure the fastening point.
8.2 –Second mounting point
The next mounting point must be placed so that the cable can be routed in an
orderly fashion when the rear frame of the bike moves through the path of
travel. This point is normally located on the front triangle.
To ensure proper cable routing we recommend that the rear shock either is
completely removed from the bike, or dismounted in one eyelet. This will make it
easier to see what effect the movement of the rear frame will have on the cable.
If there is no natural fastening point use a rubber band and zip-tie.
An easy way to ensure that the cable moves correctly is adding slack to the cable
in the direction you want it to fold. See picture. Mount the rear shock again after
the first mounting point on the front triangle has been fastened.
8.3 –To the handlebars
When mounting towards the handlebars we recommend using fastening
points that are original to the frame. If this is not possible, use the included
rubber bands and zip-ties. Mount the HYSEQ levers to the handlebar in the
preferred position.
8.4 –After assembly check list
•Can the wheel be dismounted from the frame?
•Does the cable move freely in the correct direction under the travel ratio?
•The cable does not interfere with any other function of the bike?
HUB / WHEEL INSTALLATION
17
CAUTION !
Failure to align the torque arm during hub
installation will cause malfunction and damage
to the bike frame and components.
9.1: Install the chain/belt
on the gearhub sprocket.
9.2: Install the actuator by
pressing it on the drive side
of the hub.
9.3: Align the torque
arm and insert the
wheel into frame.
9.6: Verify that the torque arm is installed in the retainer, as shown.
Correctly installed Incorrectly installed
9.4: Install, but do not tighten
the thru-axle. Position the
actuator in the desired position.
9.5: Tighten the thru-axle
according to frame
manufacturer specifications.
CHAIN TENSIONER INSTALLATION
18
10.1: Mount the chain
tensioner to the bike’s
original drop-out.
NOTE !
Unless you are installing the gearhub on a bicycle with
sliding dropouts or eccentric BB, you will need to install a
chain tensioner.
10.2: For full suspension bikes: Unbolt or let the
air out of the shock. Zip-tie the rear triangle in
the maximum travel position.
10.3: Wrap the chain around the
front and rear sprocket. Add
additional chain links according to
you bike type.
10.4: Cut, route and connect
the chain.
OIL CHANGE PROCEDURE
19
11.1: Place the wheel
against a wall at an angle.
11.2 Remove the SWAP
bolts and brake rotor.
11.3: Loosely install two
SWAP bolts as shown to
retain the gearhub in the
SWAP. Do not tighten.
11.4: Remove the oil plug.
CAUTION !
Make sure to remove all braking components before
attempting the oil change procedure. Over-filling the gearhub
will cause leakage that can damage braking components.
11.5: Position the wheel against the
wall at a 45° angle, with the oil plug
facing downwards. Let the oil drain
for 1-2 hours or more in room
temperature.
NOTE !
Please collect the used gearhub oil
and deliver it to your nearest
recycling center.
11.6: Turn the wheel around
with the oil plug facing
upwards.
11.7 Refill the gearhub with
30 ml of Kindernay Velvet
Fluid.
