WARNING
Do not modify the frame. Do not face,
grind or cut the bottom bracket shell. Any modification
will affect the bottom bracket interface and will void the
warranty.
Failure to follow these instructions may result in
hidden damage to the composite frameset. Damage to
the frameset may cause loss of structural integrity,
which may result in serious personal injury.
Only proper installation will bring out the best
performance and comfort in your frameset. Since the
installation of the Press-Fit BB adapter is a complicated
task requiring training and experience, only Giant
authorized dealers should complete the sophisticated
process.
