4. Prevent composite expose to constant high temperatures
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.
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
