high quality, innovative WheelSystem will continue to perform at the highest level.
IMPORTANT:
This manual contains important safety, performance and service
information.
Please read it before installing your new wheels or going for your
first ride and keep it for future reference.
WARNING
Compliance with the following instructions concerning assembly, handling, maintenance
and care of your Giant wheels is essential to provide proper and safe operation.
Disregarding these instructions can lead to accidents resulting in serious injuries or even
death.
Giant WheelSystems are designed and intended for use on a bicycle. The wheel or its
components cannot be used for any other applications or as a tool or toy, or in any manner
other than that described in this user’s manual. Otherwise, it is at the user’s own risk. If
you are not sure about the use condition of your WheelSystem, please consult your local
authorized Giant retailer for the intended use of the WheelSystem.
Certain Giant WheelSystems are designed to be compatible with tubeless tire (Tubeless
Ready). We strongly recommend to use Giant Tubeless tire products. If you install a nontubeless tire on tubeless WheelSystems, a rim tape and inner tube must be installed as
well to prevent the premature tire abrasion or rapid air leakage. The tires should meet the
ETRTO dimension standards to be compatible with Giant Tubeless Ready WheelSystem.
Giant WheelSystems are also compatible with non-tubeless tires. Please make install
tires with tubes and rim tape which are complying with the ETRTO standard.
Giant's WheelSystems are fully tested with Giant's recommended tires. To ensure your
safety and not to affect Giant limited warranty, Giant's WheelSystems must be used with
Giant's tires or originally supplied tires by Giant only.
Using brake pads or tires that are not or recommended by Giant may result in damage to
your WheelSystem and void your warranty.
BEFORE RIDING
Ensure that the wheels are compatible with, and properly installed in your bicycle (build in
dimensions of the frame and fork) and compatible with all other parts such as type of brake,
skewers, cassette, tire, inner tube, valve and rim tape.
If the wheel is not assembled correctly or is improperly maintained, it is dangerous and
may cause accidents with serious injury. The wheel must be assembled and maintained
by a qualified professional bicycle mechanic.

If you encounter difficulties, or are uncertain about anything identified in this user’s manual,
please contact your local authorized Giant retailer.
ASSEMBLY
Using Giant Tubeless Ready WheelSystems with tubeless
tires:
CAUTION: When assembling Giant Tubeless Ready WheelSystem (including rim tape,
tubeless valve, tubeless sealant, and tubeless tire), please refer to the set up instructions issued
by Giant or consult a qualified professional bicycle mechanic.
1. A tubeless tire should only be installed on a rim with “Tubeless Ready” marked on the
appearance of a Giant WheelSystem.
2. When assembling a Giant Tubeless
Ready WheelSystem, please use it in
combination with tubeless rim tape,
tubeless valve, tubeless sealant and
tubeless tire. If your wheels are to be
used with rim brakes, we recommend
to use Giant heat resistant tubeless
rim tape.
3. When installing the rim tape, please
ensure the tape is set in the center of
the rim bed, and make sure that the
tape overlaps 15cm on both sides of
the valve hole (Fig. 1).
4. For the installation of the tubeless
valve, please see figure 2 and figure
3.
Please ensure that the provided oring seal is positioned correctly
between lock-ring and rim (Fig. 2)
Attach the lock-ring to the valve and
tighten it finger tight (max. 0.5Nm). Do
not use any kind of tools to tighten the
valve.
5. For the installation of tubeless tires,
please see page 4.”How to install tubeless tires on Giant Tubeless Ready
WheelSystem.”
6. For filling the sealant, please see page 5 ”How to fill sea lant into Giant Tubeless
Ready WheelSystem.”

7. To achieve the best cycling performance, we strongly recommend to use Giant Tubeless
System products (rim tape, tubeless valves, tubeless sealant, and tubeless tires) in combination
with your Giant Tubeless Ready WheelSystem. Giant Tubeless System products can be
purchased from your Giant bicycle retailer.
WARNING: Use of a non-Tubeless tire without an inner tube may result in premature tire
abrasion or rapid air leakage.
WARNING: Use of a tubeless tire with Giant Tubeless Ready WheelSystem without a rim
tape and tubeless valve will result in inflation failure.
WARNING: We strongly recommend not to use tire levers when mounting the tubeless tire,
to prevent structural damage of tire and rim which may result in inflation failure.
WARNING: Use of a tubeless tire with Giant Tubeless Ready WheelSystem without sealant
may result in poor air tightness and puncture repairing functionality failure.
WARNING: To achieve the best puncture repairing performance, we strongly recommend you
to use Giant sealant. Using non-Giant sealant may result in corrosion(tire, rim, and rim tape) or
sticky tire and rim, which may lead to abnormal disassembly.
Using Giant WheelSystems with standard tires, inner
tubes and rim tapes:
1. Instead of using the tubeless valve, which can be removed from the rim, only an inner tube with
a Presta type valve (small valve, Ø 6.5mm) fits into the valve hole of the Giant rim. Never drill
out the valve hole or enlarge it in any other way.
2. Select rim tapes, inner tubes and tires which comply with ETRTO dimensions to be used with
the Giant WheelSystem and install them as instructed by the manufacturer. Do not use latex
inner tubes as heat generated by braking may damage them.
3. Air pressure: Do not inflate further than pressure limit indicated on the rim surface (see limits
labeled on it). Do not inflate further than recommended pressure limit indicated on the tire (see
recommendation values on the tire).
4. Mount the Shimano® or SRAM® cassette according to the manufacturer‘s recommendations.
CAUTION: Use tire levers carefully if they are needed. Tools with a sharp edge and improper
material of it may damage the rim. To prevent rim damage we recommend only using Giant tire
levers which are delivered with the Giant WheelSystem.

How to install tubeless tire on Giant Tubeless Ready
Valve
Opposite side of valve
WheelSystem:
Step 1:
Start from the opposite side of the valve, insert one side of the tire bead in the lowest part of
the rim bed (at in figure below, center bottom of the whole rim).
Step 2:
Start from the opposite side of valve, insert the other side of the tire bead in the lowest part of
the rim bed (at in figure below). Make sure to work toward the valve as shown in figure
below. Insert the beads of both side of the tire all around the rim in the lowest parts of the rim
bed to finish the installation. （Please DO NOT use a tire lever during the installation. Use of
tire installation lubricant may reduce the resistance of installation. Giant Tubeless System
lubricant can be purchased from your Giant bicycle retailer.)

How to fill sealant into Giant Tubeless Ready
WheelSystem:
Step1：Remove valve core from valve body by using the provided tool. (Fig. 4)
Step2：Shake the bottle well to divide particles well in the liquid. (Fig.5)
Step3：Fill sealant through the open valve body. The suggested volume is
(depending on tire size) 30~60 ml per wheel. (Fig. 6)
Step4：Reinstall valve core to valve body by using the provided tool. Ensure the valve core
and lock ring are firmly tightened. (Fig. 7)
Step5：Re-inflate the tire to the lowest maximum tire pressure. (Fig. 8)
Step6：Gently shake and spin the WheelSystem to spread the sealant well inside the inner case
of tire and cover the entire inner surface to achieve the best performance. (Fig. 9)
Step7：Assemble the WheelSystem, inflate the tire to recommended riding pressure, close the
valve and go for a ride.

Brakes:
IMPORTANT: Braking with carbon rims at slow speed may cause a shuddering sensation. Only
use Giant recommended brake pads for carbon rims. Other pads may not provide sufficient brake
performance and could overheat the rim, causing the carbon fibers to delaminate. Failure to follow
this may lead to personal injury and void of your warranty. Consult an authorized GIANT dealer
for recommended brake pads.
CAUTION: Do not use latex inner tubes on carbon rims for rim brakes, these can get hot
during hard braking, latex tubes do not withstand heat well which can cause a tire to deflate
suddenly. Failure to comply with this recommendation can void the warranty and may result in
danger. Consult an authorized GIANT dealer for recommended inner tubes.
1. Check the compatibility of the brakes, especially the brake interface of the frame, fork and
wheel. Mount the brake set and its components to the manufacturer’s recommendations.
2. When mounting and
adjusting rim brake pads,
please ensure to position the
pads at least 3mm from the
rim edge (Fig. 10). Mounting
closer to the rim edge may
result in overheating during
continuous braking or
damage to the carbon fiber. Wrong adjustment of brake pads will void the warranty.
3. The installation of 6-bolts type disc brake rotor is shown in Fig. 11. Please follow the disc brake
manufacturer’s instruction for rotor installation.
4. The installation of center lock type disc brake rotor is shown in Fig. 12. Please follow the
disc brake manufacturer’s instruction for rotor installation.
CAUTION:
Rims for disc brake wheels are designed to be used with disc brakes only. Do not install rim
brake to disc brake wheel.
6
Rims damaged by using non-Giant exclusive brake pad are not covered by your product
Figure13
warranty.
A rim will wear out with normal use. Regularly check the degree of wear and have the rim
replaced as soon as it exhibits any signs that it is worn out or damaged.
Always brake with both brakes at the same time. Avoid continuous hard braking, this can
overheat the rim and may lead to tire or inner tube failure.
Braking power is also reduced if the rim is wet or if you have new wheels or new brake pads.
Please adjust your manner of riding accordingly.
MAINTENANCE & CARE
1. Load limit of your product (the weight of rider + bike + luggage)
WheelSystems for road bike: 285 lbs. / 129kg
WheelSystems for mountain bike: 300lbs / 136kg
WheelSystems for E-bike: Consult an authorized GIANT dealer
2. Storing your WheelSystems
Carbon WheelSystems may be damaged by improper storing.
Do not hang the bike on the wheel while displaying or storage.(Fig. 13)
The carbon section of hybrid carbon-aluminum WheelSystems is not its main structure,
please do not apply external forces on this part as it may get damaged.
CAUTION: Tying the bike with the wheels to a car rack may
cause damage to the wheel because of unpredictable high forces.
3. Contact a qualified professional bicycle mechanic or your Giant
Retailer for all wheel tuning needs. Have the spoke tension and the
wheel trueness checked regularly. Spoke tension that is too high
or too low can cause high operating loads of the wheel components
and could lead to a premature failure caused by material fatigue.
4. Check the wheels regularly for any damage. Do not ride the wheels under any circumstances
if there is any damage to the rim or other components of the wheels, e.g. cracks in the rim,
broken spokes, and looseness or play in the bearings. If this is the case, contact your Giant
Retailer or a qualified professional bicycle mechanic to resolve the problem.
5. Get your bike checked by Giant dealer or qualified bike technician after every accident that may
result in damage to your WheelSystems.
6. CLEANING:
A. Wheels must be cleaned frequently with a soft sponge and a suitable cleaner. Do not use
solvents (e.g. acetone, mineral spirits, etc.).
B. Hub: The front and rear hub must be maintained at least once a year. If used regularly
under extreme conditions (e.g. strong rain, mud, transport in rain, etc.) the driver body and star
ratchet should be maintained more frequently. Frequent maintenance of the hubs guarantees
7
a longer life span and optimal performance over time. Use of high-pressure water or strong
cleaner may inject external contaminants into the hub and should be avoided. Do not use strong
solvents. (e.g. acetone, mineral spirits, etc.).
C. Sealant: to retain proper air tightness and puncture repair functionality, please follow below
mentioned maintenance frequency:
Every 2 months: check and refill sealant
Once per year: Remove old or dry sealant and clean the inside of the tire.
Improper maintenance may result in failure of sealant functionalities.
CAUTION: Before riding your bicycle, please check the tire pressure and clean all
contaminants and brake pad residue (grit, dirt, oil, etc.) from the tires, brake pad and braking
surface (particularly any traces of oil or grease) and check the wear of the brake pads, brake
surface of the rim before every ride. Replace worn out brake pads with new ones to maintain
optimum braking effect.
CAUTION: If you use Giant Tubeless Ready WheelSystems with tubeless tires, please check
your tire after riding your bicycle. If big punctures occurred on the tire, please replace your tire.
WARNING: To avoid damage to your carbon products, please do not store or transport the
product in a manner that the product is exposed to constant high temperatures. Excessive heat
can damage the resin that joins the carbon fibers. Giant suggests to ensure that the product is
kept a minimum of 45cm away from any constant source of heat, for example car exhaust,
heaters, open fire, etc.
Do not exceed 150°F (65°C) exposure to your carbon products.
