road and mountain bike handlebars.
Attach the mount to the handlebar
using the Philips head screw provid-
ed. Tighten so that the bracket cannot
rotate on the handlebar. There are
several sizing shims provided to fit
different diameter bars. If you are
using the new 31.8mm diameter bars,
you will need to purchase the
31.8mm Handlebar Mount Kit
(Specialized P/N 4812-3100) from
your Specialized dealer. To install the
31.8mm diameter strap onto your
SpeedZone Pro, remove the two
Philips head screws from the bottom
of the computer and push out the
retaining pin with a small screwdriver
or a straightened paperclip. (See fig-
ure 6) Use caution not to lose the pin
once you have removed it. Install the
other mounting strap and reinsert the
pin and screws. To test for proper
installation of the magnet, transmitter
and computer, activate the computer
by pushing the ‘MODE’ (right side)
button. Pick up the front of the bicycle
and spin the front wheel. The "wheel
option" indicator will flash. If it does
not flash, check the sensor and mag-
net alignment. Realign as necessary

placement of the magnet is correct.
(See figure 4). For the best signal
reception, adjust
angle of the transmit-
ter so that it is verti-
cal. It is not neces-
sary, or desirable to
aim the transmitter at
the computer.
Wheel magnets have
been provided for
both traditional
round spokes and
bladed (flat) aerody-
namic spokes.
For wheels with round spokes:
Attach the magnet to a spoke across
from the transmitter with the magnet
screw. The clearance between the
magnet and the transmitter should be
approximately 1/32"-1/16" (1-
2mm). Tighten the magnet and trans-
mitter. Do not over-tighten the magnet
screw. (See figure 5).
For wheels with bladed spokes;
Use some isopropyl (rubbing) alcohol
or a mild detergent to thoroughly
clean the spoke that you plan to
attach the magnet to. Remove the
backing from the adhesive tape and
firmly press the magnet onto spoke.
The tape uses a special pressure sen-
sitive adhesive. To ensure a strong
bond, please wait at least 12 hours
for the adhesive to cure before riding
your bicycle.
Your SpeedZone Pro comes pre-con-
figured with a strap to fit standard
