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.
