ZED track crankset
x1
The ZED track crankset is the first 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 fiber, 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 fixed to the crank before the crankset is fitted 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 specific tools, however we recommend you contact your
certified LOOK retailer when installing or removing it.
- Before fitting the crankset into the frame, ensure the left bearing is correctly and firmly 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.

CAUTION : Do not apply force at any time as this
may cause irreparable damage.
2 I Rotate the crankset to pre-position the right hand
bearing in its seat.
1 I Insert the crankset into the frame, starting with
the left hand crank arm.
3 I In 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.
5 I Slide the above ring + aid + screw combination
over the left-hand crank and lightly screw the ring
onto the crankset thread.
6 I Fit a 2.5 Allen key into the hole opposite the M3
screw for additional leverage, and tighten the ring.
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 specifications.
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 fittings.
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.

INSTALLING THE SADDLE CLAMP
all-guides
com
Please not that it is important to always follow
the mounting instructions described above.
6 I Position the clamp plate over the saddle rails
so that they are locked between the plate and the
asymmetrical cradle.
5 I Place your saddle in the cradle (the fittings are
compatible with all saddle rail types).
7 I Insert the spherical washer and M6x35 screw
into the M6 10x14 barrel nut and pre-tighten. Lift the
roller in the saddle clamp and use it to adjust the
saddle tilt. Tighten to a torque of 8Nm using a torque
wrench fitted with an Allen HEX5 head..
Tightening or loosening the roller allows you to
precisely adjust the saddle angle. Before every
adjustment, loosen the rear M6x35 screw, twist
the roller to adjust the saddle angle and re-
tighten the rear screw.
The holes through the side of the roller allow you to
slide an Allen key or other tool through the roller to
assist with rotation if it is difficult to do so with your
fingers.
The roller also allows you to memorise your
saddle angle for future reference. Simply remove
the rear M6x35 screw and tilt the roller forward
without unscrewing it. When reassembling your
components, tilt the roller back into position in the
saddle clamp and tighten the rear screw again to a
torque of 8Nm.
1 I Grease the surfaces of the wedge sections and
the lower half of the wedge bolt as indicated in the
illustration opposite.
2 I In order to prevent slippage, degrease the
surfaces that will be in contact with the seatpost.
3 I Slide the loosened wedge into position inside the
frame.
INSTALLING THE SEATPOST
The seatpost is supported on a stopper inside the seat tube, and held in position by a wedge.

7 I Measure the saddle height and cut the seatpost
to the desired length using the tube cutter provided.
4 I Apply a thin coat of carbon assembly paste (such
as VAR NL-78300) to the inner surfaces of the seat
tube. Do not use grease.
6 I Tighten the wedge bolt to a torque of 8Nm using
a torque wrench fitted with an Allen HEX4 head.
Cutting recommendations:
Cutting the seatpost is a delicate procedure. To
ensure a clean finish:
- using a tube cutter ensures the cut is correctly
angled. - Clamp the tube cutter firmly in a vice,
and position it so that the cut is made vertically.
- use a special carbon saw or, if not available, a
used metal saw blade. - After cutting, remove any
burrs with fine sandpaper.
CAUTION : observe the maximum cutting limits
specified on the products.
CAUTION : the minimum seatpost height is
103mm without spacers.
7 I If necessary, you will find 15 1mm spacers in
the case delivered with the bike. They can be used
following a change in the rider’s position and must
be placed between the seat post and the stop in the
seat tube.
CAUTION : It is forbidden to use more than
15 spacers per bike as the minimal seatpost
insertion length would no longer be met. This
could pose a serious risk to the rider.
INSTALLING THE REAR WHEEL
n the case delivered with your bike you will find the fittings required to install and tighten the rear wheel.
These fittings allow you to mount a Ø12mm, flat seat thru axle or a standard axle depending on the type of
wheels used.
The bike is fitted with adjustment rollers and screws on each rear dropout.

INSTALLING THE THRU AXLE FITTINGS
CAUTION : the plates must rest on the metal
surfaces, not on any carbon part as this could
sustain damage.
Excessive tightening of the axle (torque
above 10Nm) can cause permanent damage
or deformation of the fittings, and affect the
efficiency of the wheel locking system.
