Maintenance
In general, you should inspect the condition of the
bearings 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. Execessive 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.
Replacement

Consult with your Cannondale Dealer on the
quality and compatibilty of any proposed

Do not use chemical solvents to clean. Do not
remove frame material or use surfacing tools on

Frame damage, caused by improper components,

by the limited warranty.
