PowerCore press-fit bottom bracket
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.
There are different types of Press-Fit BB adapters. Be sure to check the table
below before selecting which BB adapter to use. If the BB adapter is not
suitable, serious personal injury may result.
