BB Internal Routing
NOTICE
Keep all cables and wires outside the inner bonded
alloy BB shell (1). Do not route cables or wires inside
the inner alloy shell.
Secure all mechanical cables and electronic
wires safely inside the frame, so they cannot
unintentionally enter the inner alloy BB shell
through the access holes (a). The access holes are
only to support installation and removal of parts
through the frame tube easier. Do not permit cables
or wires to unintentionally enter the shell through
these holes.
Mechanical cables and electronic wires that contact
the rotating crank set spindle can cause serious
component damage.

BEARINGS
- Repeated removal and reinstallation
can damage BB shell surfaces resulting in poor
bearing fit.
•
Do not face, mill or machine the bottom
bracket shell for any reason.
•
Repeated removal and reinstallation of BB
components could result in damage to the
shell and is not recommended.
Damage caused by improper installation/
removal is not covered under your warranty.
Bearings
Inspect bearing condition annually (at a minimum)
and anytime the crank set assembly is disassembled
or serviced. With the crank set 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.
Remove the old bearings with the bearing removal tool
KT011/.
To install bearings, use a headset press and Cannondale
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.
Following installation, apply a light coating of a high-
quality bicycle bearing grease to both sides of each
bearing to help repel moisture.
Do not re-use removed bearings. Install both bearings
as a new set.
