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.
