Maintenance
Inspect the bearing condition annually (at a
minimum) or anytime the crankset assembly
is disassembled, serviced, or if a problem is
indicated.
To inspect, when the crankset is removed,
rotate the inner bearing race of both
bearings; rotation should be smooth
and quiet. Excessive play, roughness, or
corrosion indicates a damaged bearing.
Removal
To avoid serious damage to the frame, it is
important to remove bearing systems very
carefully using proper tools indicated by the
manufacturer’s service instructions. Make
sure the bearings (cup or adapter parts) are
driven out squarely and evenly from inside
the shell! Do not pry components from shell.
