Assembly and safety instructions for
Stem adapter UP & DOWN TURN 3
Thank you for deciding to buy your new stem adapter from our company.
Compare the SAFETY LEVEL on the stem adapter with the attached
table in order to check whether it is suitable for the intended use.
Before fitting the stem adapter please make sure that it is suitable
for the max. permitted weight of the bike. You will find the relevant
details on the packing card, or alternatively you can ask your
bicycle dealer.
Before use please read the following assembly and safety
instructions carefully. Keep them in a safe place and pass
them on to the next owner if necessary.
Assembly
Basic technical knowledge is required for the assembly of this product. If you do
not have this knowledge, please use the services of a specialist bicycle dealer.
c
Check that the inner diameter of the Ahead clamp (28.6 mm)
of the stem adapter fits the outer diameter of the steer tube.
There are 2 different sizes:
with 1" steer tube: outer diameter 25.4 mm and
with 1 1/8" steer tube: outer diameter 28.6 mm.
Next you should check that the correct tube sleeve is fitted to the
stem adapter.
Here there are also two different sizes: 24.4 mm and 25.4 mm.
d
If the outer diameter of the tube sleeve does not fit the inner
diameter of the steer tube, this can be adjusted in the following way:
e
Use the 5 mm hexagonal key to release screw and remove the screw
together with washer f .
d
Remove tube sleeve with outer diameter 25.4 mm.
d
Fit tube sleeve with outer diameter 24.4 mm.
e f
Replace screw together with washer and tighten with the 5 mm
hexagonal key. The outer diameter of the tube sleeve must match the inner
diameter of the steer tube.
Before assembly the steer tube should always be treated with water-resistant
grease, because otherwise corrosion could make later adjustment difficult.
g
Now push the setting ring for the steering bearings onto the steer tube.
Make sure that the open side is facing downwards.
Next you push the shaft of the stem adapter into the Ahead clamp and then
place the clamp on the steer tube, adjusting it so that the quick release lever
is facing to the right in the direction of travel.
You should never combine the stem adapter with an aluminium
steer tube – this could lead to malfunctions.
For safety reasons the stem adapter should never be combined
with a carbon steer tube – risk of breakage.
For safety reasons the steer tube must not be more than 2 mm
shorter than the outer clamp of the stem adapter.
h
Now you tighten the Ahead clamping screw with a 5 mm hexagonal key
to a value of 9 - 10 Nm.
Finally you check that the inner diameter of the Ahead clamp of the stem
matches the outer diameter (28.6 mm) of the clamp sleeve i
adapter.
There are also 2 different sizes here:
with 1" stem clamp: inner diameter 25.4 mm and
with 1 1/8" stem clamp: inner diameter 28.6 mm
The inner diameter of the Ahead stem clamp must fit the outer diameter of the
clamp sleeve of the stem adapter.
For safety reasons the clamp sleeve of the stem adapter must not
be more than 2 mm shorter than the outer clamping area of the
stem adapter
You should also check the length of the steer tube.
The stem adapter must not be used for a steer tube which is
shorter than 155 mm.
Now push the Ahead clamp of the stem on the stem clamping sleeve
of the stem adapter. If the steer tube is longer than 175 mm the stem clamping
sleeve has to be clamped on the stem in position MAX. 1, and with a steer
tube length of 155 - 175 mm it must be in position MAX. 2.
Next you adjust the stem in such a way that is aligned with the front wheel.
Now tighten the shaft clamping screws on the stem to the tightness value
specified by the stem manufacturer.
In order to adjust the play on the bearings you use an 3 mm hexagonal key
j
to turn the setting screw in a clockwise direction until no more play or
resistance can be felt.

Height adjustment

In order to adjust the height of the steering unit you proceed as follows:
k
Release quick release lever .
By pulling the stem adapter upwards or pushing it downwards you can adjust
the height of the grip position to your individual requirements.
k
Next you close quick release lever once more.
In doing so you should check the pre-tension of the quick release lever. If there
is no longer any pre-tension you should turn adjusting screw
positioned on the opposite side, a number of rotations in a clockwise direction.
Make sure that the adapter is not drawn out
above the Stop mark.
Rotation
In order to rotate the steering unit you proceed as follows:
k
Release quick release lever .
Pull the stem adapter upwards past the Stop mark to as far as it will go.
Rotate the steering unit by 90° to the right.
Push the stem adapter downwards again.
k
Next you close quick release lever once more.

Safety instructions

The tightness of the bolts must be checked after approx. 500 km and once more
during the regular service intervals (with once a year as a minimum).
This stem adapter is not suitable for mountain biking or competitions.
The heavy demands could lead to breakage.
The height should not be adjusted during the ride. This could lead to
an accident.
To prevent the risk of a fall or accident, the stem adapter must always
be replaced if it has been damaged.
