PRODUCT, READ, UNDERSTAND
AND FOLLOW THE WARNINGS AND
INSTRUCTIONS PROVIDED IN THIS MANUAL.
IMPROPER INSTALLATION CAN RESULT IN
SEVERE PERSONAL INJURY OR DEATH.

features that are integral to the frame
and fork for proper use of the system.
Never use the 12-3-9® system on non-
compatible frames and forks. For a list of
compatible frames and forks please visit
www.naild.it

EVERY TIME YOU RIDE
WARNING:
Clamping forces should be
checked before every ride and any time the
wheel is removed and reinstalled. Before
attempting to install the 12-3-9® system
always inspect all surfaces to make sure
they are clean and free from debris and
other matter that would prevent full
engagement.
The 12-3-9® system has been carefully
engineered to be easy and intuitive to set
up and use. Once set up properly and
maintained according to the instructions
in this manual the 12-3-9® system is
very stable and should require very little
adjustment. However, the following safety
guidelines should always be observed to
ensure your 12-3-9® equipped bike is safe
and read to ride.
Always check your 12-3-9® system before
riding to make sure that the wheels are
correctly installed on the bicycle frame.
See www.naild.it for warranty terms and
conditions. Make sure that the 12-3-9®
system levers are in the CLOSED position
with the Locit® trigger fully engaged and
the CLOSED inscription on the end of the
lever visible.
Lift up the bicycle so that the wheel is off
the ground, and give the top of the tire a
few sharp downward blows as shown in the
diagram. The wheel should not be loose or
come off. Also check for side-to-side play
and make sure the disc rotors are properly
aligned and not rubbing. If the rotor is
rubbing then open the 12-3-9® system
and make sure that everything is clean and
properly adjusted and try again.
A misaligned rotor can cause the brakes
to fail resulting in severe personal injury
or death. If you are unsure how to properly
align your brake rotors take the bike to a
dealer or qualified bicycle mechanic.
These checks do not guarantee that the
quick release lever has received adequate
tightening torque. If you are uncertain as to
whether the 12-3-9® system is tightened
correctly, repeat the INSTALL AXLE AND
ADJUSTMENT section of this guide.
The Naild 12-3-9® system employs the
Quadrant Code System to provide a quick visual
reference to the appropriate use, warranty
