WARNING
Tighten hardware properly
Always tighten hardware to the specied 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

All reused-fasteners with a pre-applied threadlocker
must be cleaned with isopropyl alcohol and have new
threadlocker applied before re-assembly. If a threadlock-
