Install the computer on your bike
Install the Sensor and Magnet
1. Position the sensor unit to the inside of
the right fork blade near the top (Fig. 18). NOTE:
For best results computer and sensor should be
less than 18” apart. Attach the sensor to the fork
blade with quick ties, but do
not tighten the ties yet.
2. Attach the wheel
magnet to the spoke, aligning
the magnet with the sensor
(Fig. 19). The magnet should
have 3-5 mm clearance from
the sensor. If the sensor
and magnet are too close, or
touching, rotate the sensor
unit away from the magnet
until adequate clearance is
achieved.
3. Once correct orientation is achieved, tighten
the sensor attachment quick ties and tighten
the magnet. Trim excess quick tie length with a

scissors.
4. Attach the bracket to
the handlebar, on the righthand side of the stem. Position
the bracket end with the
Phillips head screw nearest
the rider (Fig. 20).
Your computer comes with a bar clamp which ts both 25.4
and 26.0mm diameter (mountain or road) handlebars. If your
handlebar has a 31.8mm diameter, purchase the special clamp
from your dealer.
Attach the Computer to the Handlebar Bracket
From in front of the handlebars, slide the
computer back onto the bracket until it snaps
rmly into position.
5. To remove the computer from the bracket

computer calibration. Perform the
roll-out test on a hard, at surface such
as a garage or basement oor.
Make sure the tires are properly
inated. For the highest level of
accuracy, the rider should be on the
bike during roll-out.
1. Position the bike so
that the front wheel valve

E.17
stem is at its bottom-most position.
2. Mark the ground directly under the valve
stem with chalk or a piece of tape (Fig. 23).
3. Roll the bicycle forward in a straight line
until the wheel has completed one revolution and
the valve stem is again at its bottom-most position. Make another mark, as before.
4. Measure the distance between the two
marks. Record your measurement in mm_________.
This is your wheel calibration setting.
Note: 1 inch = 25.4mm
