4. CARE & MAINTENANCE
All riders must understand the fundamental realities of composites:
• Composite materials constructed of carbon fibers are strong and light, but when crashed or overloaded, carbon fibers do not bend, they break.
• At and near the break, there will be rough, sharp edges and possibly delamination of carbon fiber or carbon fiber fabric layers. There will be no bending, buckling, or
stretching.
• Repeated loading of the fork during use can also create fatigue damage over time. Proper inspection of the fork is critical to ensure your safety while riding.
Before each ride:
• Squeeze the front brake and rock the bike forward and back. Does everything feel solid? If you feel or hear knocking with each forward or backward movement
of the bike, you probably have a loose headset. Readjust the headset as per the Assembly instructions above or have your dealer check it.
• Lift the front wheel off the ground and swing it from side to side. Does it feel smooth? If you feel any binding or roughness in the steering, you may have a tight
headset. Readjust the headset as per the instructions above or have your dealer check it.
• Check the fork for any deep scratches, cracks or discoloration. These are signs of stress-caused fatigue and indicate that it is at the end of its useful life and
needs to be replaced.
• Check the alignment of the front wheel within the fork to ensure no parts are rubbing. Readjust the wheel position if necessary.
During each ride:
• Stop and immediately investigate any new or changes in sound (squeaking/rattling), or feel (soft feel/vibration/flexibility) occurring in the area of the handlebars,
stem, fork, or front wheel. Do not ride the bicycle until the cause has been identified and properly resolved.
After a crash or significant impact:
• First, check yourself for injuries, and take care of them as best you can. Seek medical help if necessary.
• Next, check your fork for damage on the spot. Do not ride if any problems with the fork are detected. Bring the fork to your dealer for professional inspection.
• Following any significant impact, take your bike to your dealer for a thorough check. The entire fork must be inspected for damage – this requires fully removing
the fork from the frame to check all surfaces for cracks or other signs of damage. Replace the fork if any problems are detected.
WARNING: A crash or other impact can put extraordinary stress on a bicycle fork, causing it to fail or to fatigue prematurely. Components suffering from
stress fatigue can fail suddenly and catastrophically, causing loss of control, serious injury or death.
WARNING: If the fork sustains a significant impact, the entire fork must be inspected for damage – remove the fork fully from the frame to check all
surfaces.
