To remove the bottom bracket bearings
With the Campagnolo system, each of the two bearings are pressed onto one of the
halves of the bottom bracket axle. To remove the bearings, follow the Campagnolo
service instructions.
Every 3 months check the bottom bracket adjustment.
To check the bottom bracket bearing adjustment
1. Lift the chain from the chainrings.
2. Rotate the crank so that one of the arms is parallel to the seat tube.
3. Put one hand on the crank arm and one hand on the seat tube, and attempt to
move the crank arm laterally toward and away from the seat tube.
4. Spin the cranks.
If the crank feels or sounds loose, or if the motion stops abruptly or you hear a
grinding noise coming from the bearings, readjust the bearings or take the bike
to your Gary Fisher dealer.
