then push it backward until
it releases from the mount.

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.

OPERATION AND
PROGRAMMING

When your Turbo® Comp

has not detected any
speed input for 30 min­utes, it will enter sleep­mode in order to conserve
battery power. During
sleep mode only the digital
clock is displayed. The
computer will wake it up
when wheel speed is
detected or when the
MODE or SET button is
pressed. In order to oper­ate your computer it must
be placed in various
“modes” (i.e. odometer
mode, distance mode). The
computer can be cycled
through these modes by
pressing the “MODE” but­ton located on the right­hand side the MODE/SET
rocker switch. There are
nine cycling modes avail­able: 1) Clock Mode, 2)
Odometer Mode, 3) Trip
Distance Mode 4) Average
Speed Mode, 5) Maximum
Speed Mode, 6) Automatic
Timer Mode, 7)

MOUNTING THE
TURBO® COMP:

The Turbo® Comp wired
speed sensor can mount on
the right or the left side of
the fork blade. Use the
cable tie-wraps provided to
position the sensor. Do not
tighten until the final place­ment of the sensor magnet
is correct.. (See figure 4).
Wheel magnets have been
provided for
both traditional
round spokes
and bladed
(flat) aerody­namic 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
transmitter. 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 sensitive
adhesive. To ensure a
strong bond, please wait at
least 12 hours for the
adhesive to cure before
riding your bicycle.

Attach the appropriate
mount (26.0mm and

31.8mm sizes are includ­ed) to the handlebar using
the bracket screw provid­ed. Tighten so that the
bracket cannot rotate on
the handlebar. There are
several sizing straps pro­vided to fit different diame­ter bars. (See figure 6).
Slide the computer forward
onto the mount until it
‘snaps’ into place with an

Roll Out Method

The roll out method will
provide the most accurate
computer calibration and
can take into account vari­ables such as inflation
pressure, rim width and
rider weight.

1. Extend a tape measure
out to 3000mm (120 inch­es) and lock it in place.

2. With your tire inflated to
its proper pressure, place
the valve at the 6:00 posi­tion (at the bottom) directly
over the start of the meas­uring tape.

3. Roll the wheel one com­plete revolution until the
valve stem is again at the
6:00 position. Read the
tape directly under the
valve and note the distance
in millimeters. (To convert
inches to millimeters, multi­ply inches by 25.4). Use
this number to replace the
default (default values are

2073 for wheel one, and
2134 for wheel two) when
programming your com­puter. (See figure 12).
