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

. 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 http://tds.loctite.com/tds5/docs/609-EN.PDF
To remove, use tool

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 dental pick to remove any adhesive from the grooves. For Loctite clean-up

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.
