could come into contact with the frame causing the wheel to
stop suddenly. This can throw a rider off the bicycle or result in
a loss of control and crash.

AIR RELEASED FROM LEFTY AND FULLY
COMPRESSED.
Measure between the top of the properly inflated tire (1) and
the bottom of the fork steerer (2).
