SAFETY INFORMATION
Intended use
For bicycle use only. For intended use for specific model, see
“technical specification” in the manual.
Pre ride inspection
A pre ride inspection is important to identify potential
problems before each ride. STOP RIDING IMMEDIATELY if any
problems found on the following and have the wheels
inspected corrected by professional bike mechanic.
- Check and ensure that wheels are secured in the dropouts
correctly.
- Check for any visible damage on the wheels
- Check tire air pressure and inflate according to tire and
rim pressure limits with a bicycle tire pump with pressure
gauge.
- Check brakes functionality.
- Check for any residue or soiled brake track.
- Check wheels rotation, wheels should spin freely and not
wobble. Check brake clearance and any side to side
wobble.
- Check tire conditions for any cuts in thread or sidewalls
and air leakages.
Compatibility
Make sure wheelset is compatible with fork and frame.
Check clearance, chain line, brake type, dropout spacing.
Confirm specification of frame in frame manufacturer’s
manual.
Max air pressures
Do not exceed the maximum pressure of tires and rims
which could lead to failure. See tires side wall for the
maximum tire pressure indicated by different manufacturers.
Use only bicycle pumps
Do not use high volume air compressors or pumps for cars at
gas stations. These pumps moves high volume of air rapidly
which could cause tube to explode.
Crash/impact damages
After a crash or impact, stop riding immediately. Have the
wheelset inspected by professional bicycle mechanic for any
damages like bending, scoring, cracks, loose spokes.
Wheels installation/removal
Follow manufacturer’s instruction when installing or
removing the wheels. Incorrect installation may cause
wobble, wheel to fall of the bicycle or even sudden stop the
wheel which can cause serious injury. Be careful not to
damage the disc, caliper or brake pads when re-inserting the
disc into the caliper. Do not activate the disc brake’s control
lever unless the disc is correctly inserted in the caliper.
Activating the brake rotor installed may close the caliper
pads interfering with installation.

WARNINGS!
SAFETY INFORMATION
Wheel modification
Do not modify or make changes to wheels. Wheelsets are
manufactured and tested using approved components eg,
hubs, rims, spokes, spoke nipples, valves, specific tyre type.
Changing or substituting any of these parts can result in
damage to the wheel assembly leading to an accident and
voiding of warranties.
Foreign objects
Do not ride over sticks or debris (foreign objects). Foreign
objects can be kicked up, enter the spokes of the front
wheel, and be swept around and either break the fork or
stop the wheel. Riding can be littered with a great variety of
debris such as sticks, branches, auto parts and trash. Scan
ahead and if you see debris avoid as much as possible.
Before moving from your predictable path of travel, look
over your shoulder to be sure you can do so safely. If you are
riding with a group and at the front, warn rear riders and
point out debris.
Storage
Clean wheels to remove contaminants and release air
pressure before storage. Store in cool, dry areas and protect
from incidental damages during storage and from dirt
accumulation. Do not hang wheels from hooks.
Tire Size
See “Technical Specifications”in this manual for the tire size
range applicable to your model wheel. Mounting the wrong
size tires can result in the tires hitting the fork or frame
when riding. If this happens, you can lose control of your
bike and you can be thrown off. The actual measured size of
a tire may be different than its sidewall marking from various
tire manufacturer. Follow the specified tire clearance
recommendations of the frame manufacturer. Each time you
mount a new tire, take the time to inspect the actual
clearance between the rotating tire and all parts of the
frame. The U.S. Consumer Product Safety Commission
(CPSC) requires at least 1/16”(1.6 mm) tire clearance from
any part of the bike. Allowing for lateral rim flex and a wheel
or rim that is out of-true will likely mean choosing a rear tire
that provides even more clearance than the CPSC
recommends. To measure clearance: Inflate tire to operating
air pressure. Measure the space between the tire and frame.
Take measurement along the full length of possible
interference. If the measured clearance is less than specified,
the tire is not compatible and must not be used.
Transporting
Protect the wheels from damage during storage. Do not use
a clamp on any part of the wheel rim, spokes, or hubs. When
transporting on an automobile rack, make sure wheels are
not within 18”of the hot exhaust pipe.

SAFETY INFORMATION
Brakes
Follow brake manufacturer’s instruction for installation,
using and maintenance of brake system parts eg. Disc,
callipers, pads.
Disc brakes (road bikes)
Relative to conventional rim brakes, disc brakes are less
affected by water, do not wear or heat the rims, and are
therefore more consistent. Disc brakes also may be more
powerful. To minimize risk of injury or accidents: Understand
that road bikes have a relatively small tire contact patch (part
of the tire that touches the road). In order to apply the
brakes safely and effectively, you may need more or less
braking force in different situations. You need to take into
account various road and weather conditions that can affect
traction. Take some time riding your new disc brake road
bike in lower-risk circumstances to get used to the feel and
performance of the disc brakes and tires.
Disc brakes only rims
Do not use disc brake only wheels with rim brakes. There
is no rim braking track on disc brake only wheel rims. Only
disc brakes can be used. See “Technical Specifications” for
applicable brake types and limitation for your specific wheels
Braking correctly
Braking with carbon rims is quite different from aluminium
rims. Do not keep the brake pads in constant contact with
the rims which could cause severe heat build up on brake
track areas and cause delamination of carbon fibres. Braking
effect then become hard to control and also causing wheel
to be permanently damaged. Operate the brakes at intervals,
shorter but harder. The longer the brake is released between
braking intervals the better.
Extreme temperature
Do not expose the wheels (and/or bike) to heat such as in
strong sunlight under the glass of a hatchback auto.
Exposure to excessive heat can damage the wheel leading to
wheel failure.
Maintenance
Establish a wheel/bike maintenance and inspection schedule
appropriate for how you ride and use the wheels. Inspect
more often when riding aggressively and in extreme
environmental conditions. Have all inspection and
maintenance performed by a trained professional bike
mechanic. See “Maintenance” in this manual.
Cleaning
As with your bicycle, clean with dish soap and water. Never
use solvents, spray oils, or chemical spray cleaners to clean.
These can damage/weaken the structure of the wheel and
cause decals, labels, and paint to come off. Do not use a
pressure washer, which can cause damage by forcing dirt and
debris into the wheel.

INSTALLATION
Casette
Ensure your cassette is compatible with the ordered free hub
option. For road, Shimano 11-speed free hub is compatible
with Shimano/SRAM 11s cassette and 10s along with the
spacer included with the wheelset. Campagnolo free hub use
only cassette by Campagnolo. For MTB, Shimano free hub is
compatible with Shimano 11s/SRAM 10s cassette. Sram XD-R
compatible with Sram 11/12s. Shimano micro spline hub for
Shimano 12s cassette. Insert cassette according to
manufacturers instructions and tighten lock ring with correct
torque specified by manufacturer. Use a torque wrench and
special tools designed for this purpose. [ Ref fig 1 ]
Installing the tyres
Only use suitable plastic tyre levers when removing your
tyres- do not use metal tyre levers under any circumstances.
Only use high quality and undamaged clincher/foldable
clincher with suitable inner tubes or tubeless tyres. Observe
the min/max inflation pressure values specified by
manufacturer.
The lower the inflation pressure or tyre width the higher the
risk of pinch flat. In most cases it will be the rim flange to
suffer from damage. [ Ref fig 2 ]

CAUTION!
INSTALLATION
Installing the wheels
Risk of accident through malfunction of the quick release
skewers caused by improper assembly.
Make sure quick release skewers complies with the
dimensions specified.
Mount your wheels in your bike’s dropouts and make sure
that after closing, the levers are in a position that prevents
accidental opening while riding. Eg due to trapping. [ Ref fig
3 and 4 ]
Risk of accident by blockage of the rear wheel caused by
incorrectly positioned rear derailleur.
Make sure derailleur hanger on bike frame is parallel to the
sprocket set.
Make sure the chain cannot move beyond the largest
sprocket and to maintain a minimum clearance 1-2 mm
between pulley cage and rear wheel spoke.
Shift the chain to the smallest chain ring.
Carefully shift the chain to the largest sprocket.
Re-adjust the inner limit stop of your rear derailleur if pulley
cage is less than 1-2mm to rear wheel spoke.

CAUTION!
INSTALLATION
Installing the brakes
Only use original brake pads supplied by Rotac or brake pads
for carbon rim only. Do check with us on the compatibility if
you are intending to change to other make of brake pads
prior installation.
Ensure all brake pads are correctly installed as follow:
Brake pads with L labelling indicates it must be installed on
the left hand side brake shoe and pads with R labelling
indicates it must be installed on the right hand side brake
shoe.
Slide the brake pads into the brake shoe.
Shimano/Sram: Tighten the securing bolts with a torque
wrench of 1 –1.5 Nm
Carefully adjust brake shoe, to ensure pads are positioned on
the center of the brake track and tighten the bolts on the
brake shoes:
Shimano/Sram: 5-7 Nm
Campagnolo: 8 Nm
Adjust the clearance between brake pads and brake track of
both sides to be equal.
Race bikes are generally fitted with a ‘wing’ used as a guide
during installation of wheel. The ‘wing’ may come into
contact with the rim if the pads is more than 50% worn. [ Ref
fig 5 ]
Check on a regular basis on the distance between ‘wing’ and
surface of rim, when distance is less than 1mm. Replace
brake pads.
