1 INTRODUCTION
2 INTENDED USE OF THIS MANUAL
3 PRECAUTION
3
Propel disc series bicycles feature professional-grade frame technology used by world
champion racers. These frames are handcrafted with the most advanced materials, engineering
and construction methods.
Composite parts are different from metal parts, therefore the treatment to the composite parts is
also different.
1. Prevent composite parts from sharp edges or excessive pressure
Sharp edges or clamping mechanisms can damage carbon fiber composite by creating a
stress load or high pressure point. Please follow these procedures to make sure the parts
or components are carbon-compatible before installing any carbon fiber part, or attaching
any component to an existing carbon fiber part.
It is normal, and no reflection of the strength of the frame, that you may feel movement in the tubes
when you squeeze them. However, repeated compression of the sides of the tubes could eventually
lead to frame damage. Do not squeeze the frame tubing, and never clamp the tubing in any
mechanical device, including car racks.
2. Clean before installation of carbon fiber composite parts
With some interfaces of metal parts, grease is used on the clamping surfaces to prevent
corrosion. When adjusting, always grease the bolt threads. Grease reduces corrosion
and allows you to achieve the correct tightness without damaging tools.
However, with most carbon parts you should avoid grease. If grease is applied to a carbon part that
is clamped, the part may slip in the clamp, even at the recommended torque specification. The
carbon part should be assembled in a clean, dry state. Contact an authorized Giant retailer for
special carbon prep products recommended by Giant.
3. Never modify the fork, frame or components
The parts of the Propel disc series framesets have been precisely designed to meet
strength and function requirements for safe riding. Modifying these parts in any way may
make the bike unsafe. Only an authorized Giant dealer should perform some of the
modifications illustrated in this manual. For example, cutting the ISP.
Never use suspension forks on a road bike frame. It can add stress and damage the frame. Do not
change the style and/or length of forks. If you are unsure if a fork is compatible with a frame, contact
your authorized Giant dealer. Any modification of a frame, fork or components means that the
bike no longer meets our specifications and therefore voids the bike’s warranty.

4. Prevent composite expose to constant high temperatures
To avoid damage to your carbon products, please do not store or transport t he 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, f or example car exhaust, heaters, open fire, etc.
Do not exceed 150°F (65°C) exposure to your carbon products.
Propel disc bikes feature OverDrive 2 to offer unprecedented steering performance with no additional
weight. The OverDrive 2 headset features massive 1 1/4-inch top and 1 1/2-inch bottom bearings and
provides up to 30 percent more torsional steering stiffness.
Once the headset assembled, make sure that some play exists between:
•
the fork crown and the bottom of the headtube
•
the top of the headtube and the conical spacer
So the steer rotates freely and easily without resistance.
There is no minimum clearance value but only a recommended value:
•
upper clearance : 0.5mm
•
lower clearance : 1.0mm
To learn more about OverDrive 2 technology, please visit the Giant website at giant- bicycles.com.

Steering tube
The steering tube of the Propel disc forks are constructed with carbon fiber material for light weight
and optimized stiffness.
Please contact your authorized Giant dealer to modify the steer length to your preference. If you are
a qualified professional mechanic, please follow these instructions:
CAUTION:
1. Always use a quality hacksaw with a fine-
tooth blade when cutting the steer tube. A
poor quality blade could damage the steer
material.
2. Lay the fork on a flat, stable surface. Use
a professional saw guide to help you cut.
Measure twice, cut once!
3. Do not clamp the composite steer with
more than 8Nm of torque. Over-clamping
force could damage the steer tube.
4. A professional saw guide for steer cutting
is must to be used. For example: PARK
TOOL Oversized Adjustable Saw Guide.
Fork structure
Do not file the fork safety tabs or drill any holes in the fork structure.
WARNING: The fork has been designed to optimize performance. Do not modify the fork by
drilling or filing. Any modification will affect the fork structure and damage it. This may result in
serious personal injury or death.
WARNING: Any modification of a frame, fork or components means that the bike no longer
meets our specifications and therefore voids the bike’s warranty.

WARNING: Failure to follow these instructions will void your warranty, and may result in
hidden damage to the ISP. Damage to the ISP can cause loss of structural integrity, which
may
result in serious injury or death.
A proper saddle height is essential for experiencing the best performance and comfort in your bicycle.
To meet the correct saddle height, the ISP may have to be cut to a specific length. Cutting the ISP is a
complicated task that requires training and experience. Please visit your authorized Giant dealer to
perform this sophisticated process.
ISP cutting instructions
Step 1: Determine the length to cut
Install the saddle onto the seatpost using the included saddle clamp mechanism. Put the saddle in a
horizontal position and then determine the length to be cut.
CAUTION: The additional range of saddle
height adjustment (utilizing the included
spacers) provides fine-tuning adjustment
after the ISP is cut.
WARNING: The final cut length must not
exceed the maximum cutting length limits
(see chart below).
Cutting the ISP length more than this limit
may result in the inability to attach the seat
clamp and can cause structural failure of
the ISP.

Step 2: Disassembling for cutting
Loosen the saddle clamp bolt and remove the saddle.
Step 3: Cutting the seatpost
NOTE: A professional saw guide for seatpost cutting is must to be used. For example: PARK TOOL
oversized adjustable saw guide.
CAUTION: Use a fine-tooth (32-tooth) saw blade to avoid fraying the composite fibers. Take
care when finishing the cutting process to not splinter the composite.
WARNING: Be sure to wear appropriate safety equipment such as glasses, gloves and a dust
mask. Make sure not to inhale any of the dust!
·
Lay your frame flat on a clean surface, protecting the finish with a clean soft cloth at points of
contact.
·
Place the Saw Cutting Guide at the precise location of the desired cut.
·
Be sure to double-check your measurement. Measure twice, cut once.
CAUTION: There is no way to restore the frame to a higher saddle height after the ISP is cut.
Please make sure your measurement is correct and that you cut precisely.
Step 4: Clean the cut
Remove the saw guide and carefully sand down any burrs with fine emery paper. Clean off the dust
with a damp rag and discard it immediately.
Step 5: Assemble the saddle clamp
Install the saddle clamp onto the ISP and tighten the
clamp seatpost bolt to standard torque value.
CAUTION: Do not grease the ISP or the inner
side of the saddle clamp.
•
Adjusting or correcting the saddle height
The saddle height can be corrected with washers.
WARNING: Do not raise the seat clamp without
washers or with more than 30mm of washers.
This may result in damage to the ISP.
ISP failure may result in serious
personal injury
or death.

The Giant Vector Seatpost is built with Giant Composite Technology for lightweight, aerodynamic
performance. To achieve the best riding experience and proper saddle height, the seatpost may need to
be cut.
WARNING
·
Cutting the seatpost is a complicated task that should be performed by a professional
mechanic.
·
If you have any doubts about your ability to cut the seatpost correctly, please contact an
authorized Giant dealer.
·
Failure to follow these instructions will void your warranty, and could damage the frame
and/or the seatpost, which may result in severe injury or death.
CAUTION: Use the carbon assembly paste for final installation, which could prevent the
seatpost from slipping down and damaging the frame. It could also prevent p ossible creaking
due to the friction between the frame and the seatpost.
Seatpost Cutting Procedure
Determine the length to cut
1. Install your saddle to the Giant Vector
Seatpost and adjust the saddle to a horizontal
position.
2. Adjust the seatpost up and down and
determine the correct saddle height. If the
saddle cannot be lowered far enough for
proper fit, because the seatpost meets the
seat tube curve inside the frame, the seatpost
must be cut.
3. The seatpost should be cut at a 45-degree
angle so that the bottom of the post slopes
downward from the rear side to the front. This
will help prevent damage to the frame if the
seatpost is pushed too far down in the frame.

The seatpost should be cut from its original condition when the saddle height that you require is lower
than the minimum saddle in the chart above.
Note: The maximum seatpost insert depth is at 30mm above than the seat tube curve. Do not let the
seatpost reach the seat tube curve shape when riding the bike.
WARNING:
·
Be slow and c areful when inserting the
seatpost into the seat tube. Too much
downward force may damage the frame
and/or the seatpost.
·
The minimum insertion of the Vector
seatpost is 90mm. Do not overcut the
seatpost. It is necessary to make a precise
measurement before cutting the seatpost.
·
If the seatpost reaches the seat tube curve
shape when riding the bike, it will damage
the frame.
Cutting the seatpost
4. It is recommended that you use a professional saw guide and a fine-tooth saw to cut the seatpost.

side to the front side. This will help prevent damage to the frame if the seatpost is pushed too far
down.
CAUTION: Use a fine-tooth (32 teeth) saw
blade to avoid damaging the composite
fibers.
WARNING: Be sure to wear appropriate
safety equipment, such as glasses,
gloves and a dust mask. Make sure not
to inhale any of the dust!
7. Make a clean cut carefully.
CAUTION: Do not splinter the composite when finishing the cutting process.
8. Remove the saw guide and carefully sand-down any burrs with fine emery paper. Clean off the dust
with a damp rag and discard it immediately.
9. Install the saddle onto the seatpost and recheck the target saddle height.
