If the fork ever begins to make “knocking” or “klunking” 
noises, or if it ever shows an unexplained increase in travel, 
or looks like it is extended farther than it was originally, or 
if the fork loses its ability to lock out, stop riding the bike 
and bring it to a HeadShok dealer for inspection. Possible
indications of a problem are:

An increase in the fork’s extension or travel.

A stretched-out fork boot (See above.)

A stretched or strained front brake cable. 

“Knocking” or “klunking” noises coming from the fork.

A sudden loss of lock-out ability.

If any of the above symptoms are ignored, the result could 
be a separation of the fork from the bicycle frame, leading 
to an accident with risk of serious injury or death to the rider.
