Bearing Maintenance
Inspect bearing condition annually (at a minimum) and anytime the crankset assembly is disassembled or serviced. With the
crankset removed, rotate the inner bearing race of both bearings; rotation should be smooth. No play or movement inside the
shell. If the bearing is damaged, replace both bearings with new ones.
Bearing Removal/Installation
(Professional Bike Mechanic Only)
Remove the old bearings with the bearing removal tool
KT011/
.
Reinstall bearings with a headset press and tool
KT010/ .
Clean inside of shell apply a high-quality bicycle bearing grease to the
inside surface. Press bearing one at a time. Press each bearing until seated against the circlip. Following installation, apply a
light coating of a high-quality bicycle bearing grease to both sides of each bearing to help repel moisture.
TIP:
Unless a circlip is damaged, removal is unnecessary during bearing removal . Use a small thin-blade screw driver or pick to lift
the hooked end up out of the groove and then pushing the circlip out counter-clockwise.
Adapter Removal/Installation
(Professional Bike Mechanic Only)
To install, first remove the bearings and circlips and clean the inside of the BB shell and adapter. Use a clean lint-free shop towel
dampened with alcohol. Apply Loctite™ 609 carefully to the bearing seat positions to both shell and adapter. Install the adapter
with a headset press and the installation tool
KF368/
. Adapter groove must be located on the BB drive side. Press until the
groove side face is flush with the drive side face of shell. Allow at least 12 hours (at 72°F) for the Loctite to cure before installing
the standard bottom bracket crankset. Follow Loctite Technical Data Sheet

To remove, use tool
KF366/
with a headset bearing press with tool arrangement as shown. Following removal, it will be
necessary to clean all remaining Loctite residue with a before reinstalling the Si circlips and bearings. Use Loctite 768. Use a

NOTICE
BEARINGS -
Frequent or routine renewal of undamaged bearings is not recommended. Repeated removal and reinstallation
can damage the inside BB shell surfaces resulting in poor bearing fit. Do not face, mill or machine the bottom bracket shell
for any reason. Doing so can result in serious damage and possibly a ruined bike frame.
ADAPTERS
- Use only adapters/tool recommended by Cannondale. Other available adapters /tools may cause damage.
See Replacement Parts. An adapter isn’t a “repair” part, so the BB shell must be in good condition. Repeated removal and
reinstallation of an adapter, or improper tools can cause damage. Therefore it is not recommended.
Loctite 609 - Prolonged contact with the frame finish may result in discoloration or damage. Be sure to immediately wipe up
any spills and remove any compound in contact with the painted surfaces.
Do not cut, face, or use abrasives to clean the inside if the BB shell.
We strongly recommend that these procedures be performed by an Authorized Cannondale Dealer. Damage caused by
improper installation/removal is not covered under your warranty.
