the transmitter should be
approximately 1/32”-
1/16” (1-
2mm). Tighten
the magnet and
transmitter. Do
not over-tighten
the magnet
screw.
(See figure 5).
For wheels
with bladed spokes:
Use some isopropyl (rub-
bing) 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 sensitive
adhesive. To ensure a
strong bond, please wait at
least 12 hours for the
adhesive to cure before rid-
ing your bicycle.
Attach the appropriate
mount (26.0mm and
31.8mm sizes are includ-
ed) to the handlebar using
the bracket screw provided.
Tighten so that the bracket
cannot rotate on the han-
dlebar. There are several
sizing straps provided to fit
different diameter bars.
(See figure 6). Slide the
computer rearward onto
the mount until it ‘snaps’
into place with an audible
click. To remove the com-
puter, remove the cadence
wire (if connected) then
push it forward until it
releases from the mount.
To test for proper installa-
tion of the magnet, trans-
mitter and computer, acti-
vate the computer by push-
ing 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 magnet
alignment. Realign as nec-
essary until the “wheel
option” indicator flashes
while spinning the wheel

from the transmitter hous-
ing. Install the battery
(model 23A) with the posi-
tive pole (+) facing
upward. Carefully thread
the battery cap back onto
the case with a coin.

INSTALLATION
MOUNTING THE
TURBO® PRO:
The Turbo® Pro wireless
transmitter can mount on
the right or the left side of
the fork blade. The right
side should be used on
large frames or when a
suspension fork is installed.
The optimal distance
between the computer and
the transmitter is 24 inches
(610mm). The distance
may need to be less than
24 inches (610mm) if
ambient temperatures are
below 40 °F (4 °C). To
reduce signal loss in colder
temperatures, the transmit-
ter should be mounted as
close to the computer as
possible. (Maximum
mounting distance is 28
inches). Use the transmit-
ter-mounting shim and tie-
wraps provided to position
the sensor. Do not tighten
the tie-wraps until final
placement of
the magnet is
correct. (See
figure 4).
Wheel magnets
have been pro-
vided 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
