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.
