Safety
WARNING
Properly tighten hardware
Always tighten hardware to the specied torque.
Over-tightening hardware could deform or break the
hardware or components. Under-tightening hardware
could cause hardware or components to become loose.
Either situation could damage the bicycle and result in
injury to the rider.
WARNING
Reapply threadlocker
All reused-fasteners with pre-applied threadlocker must
be cleaned with isopropyl alcohol and have new thread-
locker applied before re-assembly. If threadlocker is not
applied, the fasteners may loosen which could damage
the bicycle and result in injury to the rider.

Install the bottom bracket
1. Apply grease to the threads on both sides of the
frame.
2. Using your hands, thread the bottom bracket onto
the frame.
NOTICE: Do not start tightening the bottom bracket
with a tool. Dirt and other contaminants can damage
the threading.
3. Use the proper tool to torque both sides to
specication (see the Tool and spline compatibility
table below).
4. If necessary, add spacers before installing the cranks
(see the Spacers required table at the top right).
Spacers required
The table below contains bottom bracket/crank
combinations that require spacers. Your bicycle may have
other combinations that do not require spacers.
