Safety

WARNING.
Properly tighten hardware Always tighten hardware to the specified 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 thread locker All reused-fasteners with pre-applied thread locker must be cleaned with isopropyl alcohol and have a new thread-locker applied before re-assembly. If the threadlocker is not applied, the fasteners may loosen which could damage the bicycle and result in injury to the rider.

T47 bottom bracket
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.

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.
