INSTALLING THE FRONT WHEEL FITTINGS
In the case delivered with your bike, you will nd a bag containing all the necessary parts to install the ttings
compatible with your wheels.
These ttings allow you to mount a Ø12mm, at seat thru axle or a standard axle depending on the type of
wheels used.

5IBefore tightening the 4 screws completely, grease
the thread of the thru axle and screw it partly into
the M12 nut while still allowing access to the M3x5
screws. This will ensure that the ttings are aligned.
Remove the thru axle and tighten all 4 M3x5 screws
to a torque of 1 Nm.
6 I Grease the thru axle thread. Install the wheel
and tighten the axle (H6 Allen wrench) to a torque
of 10Nm.
WARNING : Ensure the screw heads do not
protrude beyond the counterbore, or the axle will
rest on the screw heads rather than on the at
surface of the washer.

WARNING : Ensure the screw heads do not
protrude beyond the counterbore, or the axle will
rest on the screw heads rather than on the at
surface of the washer.
Using wheels with different axle types requires swopping the ttings regularly. After assembling/
disassembling three times it is important to recoat the screw threads with a standard threadlocker
such as LOCTITE 243TM. Do not grease or lubricate the screws !

2IGrease the M6x10 extraction screw (4).
1IDegrease the cones (1 & 6), the headset cap (3)
and the stem with a clean cloth.
3IManually screw the M6x10 screw into the left
cone and tighten until it rests on the small diameter
of the cone.
4ILine up the cones in the headset cap. The hole in
the right hand cone must be aligned with the thread
of the left hand cone.
5 I Apply light pressure to the cones to ensure
they stay in place in the headset cap. The cones
must not protrude from the headset cap before
mounting the stem.
6IPosition the stem on the headset cap.
7 I Align the holes in the stem with the holes in the
cones. Then pre-tighten the 6 M5x30 screws
(coated in threadlocker such as LOCTITE 243) to
hold the stem in place.
8 I Adjust the stem angle. Stem angles can vary
between +20° and -9° (horizontal reference).
9IEvenly tighten each of the FHCX M5x30 screws
to a torque of 8Nm using a torque wrench with a T25
head. To ensure the screws are evenly tightened,
alternately tighten the left and right screws.
The right hand screws go through the right side of
the stem and tighten into the left cones and vice
versa.

MOUNTING THE HANDLEBAR ON THE STEM
1IDegrease the face plate (10), the handlebars (9)
and the stem (7).
2IGrease the M5x30 screw (8) threads and heads.
3IPlace the barrel in the face plate. The barrel sits
under the stem (see diagram opposite).
4IPre-position the handlebar in the stem.
5IPlace the lower part of the face plate against
the stem.
6 I Fold the upper part of the face plate onto the
stem.
7IFit the stem screws (CHC M5x30 coated in
threadlocker such as LOCTITE 243) into the stem
from above and tighten to a torque of 8Nm using a
torque wrench tted with an Allen HEX4 head.
Approved handlebar width : 31.8mm. Minimum clamp area width: 45mm.

ANGULAR ADJUSTMENT I REMOVING THE STEM
1ILoosen the 6 FHCX screws (by approx. 3mm)
without removing them completely.
2 I Place a 5mm Allen key in the central stem hole,
on the right hand side.
3ILoosen the central M6x10mm screw until one of
the 2 cones comes away from the headset cap.
4IContinue unscrewing until the second cone
detaches from the headset, taking care not to pull
the composite arms away from the stem.
5IOnce you have removed both cones, the stem
angle can be adjusted. The stem can also be
removed by completely unscrewing and removing
the 6 FHCX screws.
6IDo not forget to tighten the M6x10 screw in the left
cone before tightening the stem on the fork again.

EN
The ZED track crankset is the rst carbon monobloc track crankset in history. The crank arms and spider
are integrated with the bottom bracket axle to achieve a stiffness that is unequalled on the market today.
Built solely from carbon ber, the crankset is lightweight and extremely stiff. The ZED track version is the
result of many years of research and development, and features many of LOOK’s patented technologies,
including the adjustable crank arm length thanks to the tri-lobe system. This means that one crankset
can offer crank lengths of 165 - 167.5 - 170mm (size 1) or 172.5 - 175 - 177.5mm (size 2), simply by
twisting the locking nut on the pedal by one third of a turn. The adjustment is fast, easy and does not
require any special tools.
This monobloc technology links the crank arms and axle to a solid spider, which supports the chainring.
The seamless continuity between the chainring and the spider improves the aerodynamics of the entire
component.
As the ZED track crankset is made of one single piece, installing it requires sliding the left crank arm
through the frame. The right hand pedal can be xed to the crank before the crankset is tted into the
frame. This is not the case for the left hand pedal, which can only be attached once the ZED crankset is
correctly installed.
- Installing the ZED crankset does not require specic tools, however we recommend you contact your
certied LOOK retailer when installing or removing it.
- Before tting the crankset into the frame, ensure the left bearing is correctly and rmly positioned in the
left hand side of the frame, and that there are no parts missing from the pre-assembled components on
the crankset. - The chainrings do not interfere in any way with the crankset installation procedure. The
crankset can be mounted in the frame with or without the chainrings.
INSTALLING THE ZED CRANKSET IN THE FRAME
CAUTION :
- Dust, clean and grease the crankset bearing seats with the recommended lubricant.
- Never clean your bike with a high pressure cleaner. Pressurized water, even coming from a simple
garden hose and despite the seals, can penetrate into the ZED crankset and cause irreparable damage
to the components and bearings. Gently wash the crankset when it is mounted on the bike, using a soft
cloth, water and neutral detergent.
- Never leave the ZED track crankset inside a car parked in direct sunlight, close to a radiator or any
other source of heat.

17
EN
CAUTION : Do not apply force at any time as this
may cause irreparable damage.
2IRotate the crankset to pre-position the right hand
bearing in its seat.
1IInsert the crankset into the frame, starting with
the left hand crank arm.
3IIn a smooth and linear movement, slide the whole
crankset leftward to bring the right hand bearing into
its seat.
4 I Prepare the locking ring by inserting the
mounting aid into the 1mm slit and locking it in using
the M3x30mm screw.
5ISlide the above ring + aid + screw combination
over the left-hand crank and lightly screw the ring
onto the crankset thread.
6IFit a 2.5 Allen key into the hole opposite the M3
screw for additional leverage, and tighten the ring.

18
EN
7 I After removing all play in the crankset by
tightening the locking ring, remove the Allen key,
loosen the M3 screw, remove the mounting aid and
re-tighten the M3 screw to a torque of 2Nm.
To remove the crankset, follow the assembly
procedure described above in reverse order.
REMOVING THE CRANKSET
MOUNTING THE CHAINRING ON THE CRANKSET
Chainring compatibility :
Chainrings with the following properties are compatible with the ZED TRACK crankset :
- 5 bolt holes
- 144mm bolt circle diametre (BCD)
- 4mm thickness in all bolt areas
Most current chainrings meet the above specications.
Mounting the chainring on the crankset :
With the crankset installed on the bike, slide the chainring over the right hand crank and tighten the
mounting screw to a torque of 6Nm.
Note: the chainring locknuts are integrated in the crankset. Only the mounting screws need
inserted and tightened to attach the chainring.

INSTALLING THE SADDLE CLAMP
Before cutting your seat tube, please assemble the saddle clamp with the provided ttings.
Select either the short or long saddle clamp depending on the fore-aft position required. These saddle
clamps are reversible to achieve the desired position and virtual seat post angle. Each must be used with its
respective clamp plate: short clamp + short clamp plate / long clamp + long clamp plate.
