While riding your bicycle, do not stare
at the computer for long periods of
time (Figure 1). If you do not watch
the road, you could hit an obstacle,
which may cause you to lose control
and fall.
Make sure the computer wire cannot
contact the tire or wheel spokes (Figure
2). The wire could be damaged causing
the computer to malfunction. Also, the
wire could get caught, causing you to
lose control and fall.

Placing the computer on the handlebar
The Trek Incite 9i or 11i computer can be
mounted on the handlebar or on the stem
(Figure 3).
To install the computer on handlebar
1. Select the bar clamp that fits your bike.
31.8mm bars: large clamp
25.4mm and 26.0mm: small clamp
22.2mm bar: small clamp with rubber shim
Figure 4- Clamp and friction pad
in computer base
2. Insert the handlebar clamp into the back
of the computer base (Figure 4) and slide
it towards the front of the base.
3. Insert the rubber friction pad into the computer base, aligned
across the computer base.
4. With the wire pointing toward the front of the bike, wrap the bar
clamp around the handlebar.
5. Insert the screw through the washer and into the computer base.
6. Tighten the screw until the computer base cannot rotate on the
handlebar.
7. Slide the computer into the computer base until the front of the
computer and computer base line up.

Check that the computer base cannot
be rotated around the handlebar,
and that the computer cannot slide
backwards on the computer base
(Figure 5).
To install the computer on the stem
1. Insert the rubber friction pad into
the computer base, aligned along the
computer base.
Figure 5- Make sure the com-
puter cannot be bounced off.
2. Insert two nylon ties through the
computer base (Figure 6).
3. Place the base on the stem and tighten the
nylon tie.
4. Slide the computer into the computer
base until the front of the computer and
computer base line up.
5. Check that the computer base cannot be
rotated around the stem and the computer
cannot slide backwards on the computer
base.

Placing the magnet
The wheel magnet must be aligned so that it passes across the
sensor. As the magnet passes the sensor, it must be no further
from the sensor than 1 to 3mm (1/32 to 1/8 inch).
The wheel magnet has a ‘T’ shaped slot with two configura-
tions: round spokes and flat or bladed spokes (Figure 7).
To install the wheel magnet
1. Remove the screw from the magnet.
2. Slide the slot in the back of the magnet
over the spoke.
For a flat or bladed spoke, start the
spoke near the end where the spoke is
round, and align the top of the ‘T’ with
the spoke as you slide the magnet up the
blade (Figure 7).
3. Thread the screw into the magnet until it

Attaching the computer wire
The computer wire is usually longer than needed. Extra wire
length can be diverted by wrapping it around the brake housing
prior to routing it down the fork blade or down tube (Figure 8).
Make sure the computer wire is not pulled tight when the
handlebar is turned all the way to either side.
To attach the computer wire
1. Determine the length of wire to divert by
holding the sensor at its desired mounting
point.
2. Wrap the wire around the front brake
cable, diverting the determined amount.
3. Continue routing the wire, either by
wrapping around the fork or frame tube,
or attach the wire to the fork or frame
tube with electrical tape.
Figure 8- Trim excess nylon tie
4. As needed, solidify the wire attachment
length
with either nylon ties or electrical tape.

Attaching the sensors
The magnet must pass across the line on
the sensor (Figure 9).
These instructions are written for
the front wheel, but apply equally to
installing the magnet and cadence
sensor which go on the left crank and
the frame’s chainstay (Figure 10).
1.0 -
3.0mm
To install the sensor
1. Align the sensor with the magnet.
Figure 9- Magnet alignment and
clearance
2. Orient the sensor so that the clearance
between the sensor and the magnet is
between 1 to 3mm.
The sensor can be rotated around the fork
about 45 degrees.
If needed, the sensor and magnet can be
moved up or down the spoke and fork to
change the amount of clearance.
3. Attach the sensor with nylon ties, but do
not fully tighten.
4. With the computer in the computer
base, check the alignment of the sensor

displaying speed.
If the computer shows current speed, the sensor is
reading the magnet.
If the computer is not displaying a value, realign the
sensor and magnet until one is displayed.
5. Tighten the nylon ties and trim the excess
length (Figure 11).

EASy SETuP (RESET)
You can program the starting values of your computer in a
single, easy procedure:
• Units
• Clock
• Wheelsize
• Odometer
The Units setting tells the computer which conversion to use:
metric or SAE (“English”):
MH = miles
KMH = kilometers
You can set the clock for 12 or 24 hour display, which changes
how time appears in the afternoon, such as 3PM:
12 hour clock
24 hour clock
3:00
15:00
You can set the wheel size by simply choosing from a menu
listing tire sizes, or you can set custom values listed in a chart.
For the most precision, do a “rollout” test. The rollout test is
described on page 22.
You can set the odometer to be at “0” or you can start at a
different value. This allows you to keep track of your previous
mileage after the computer has Reset (started over at 0), such
as after installing a new battery.

Once the computer is programmed and installed, it is very easy
to use. To change to different modes (functions), simply Cycle
the Mode button until the desired function appears, shown by
the spelled name of the function.
Removing the computer from the computer base
The computer is held on its base by a flexible snap. To remove
the computer, press firmly on the computer (not on the base) in
a rearward direction.
using the computer in wet weather
Bicycle computers function on electricity. If the electrical
contacts between the computer and its base become saturated,
the electrical signals may become irregular or interrupted
entirely. If the computer is to be used in heavy rain, etc., we
recommend that a plastic bag be put over the computer and its
base. The other parts of the computer system are waterproof.

REPlACINg ThE BATTERy
If the computer is giving erratic information, the computer or
hear rate strap battery may be running low on power (normally
accompanied by the low battery icon, Figure 16). Replace the
batteries whenever the computer malfunctions, or every 6
months. When purchasing new batteries, it is best to take the
old batteries with you. However, this is the generic description
for the proper battery:
CR2032, lithium cell, 3 volts
When the battery is removed, the computer automatically
resets function totals to Zero. After installing a new battery, you
can manually set your totals, but you must note those values
before removing the battery.
To replace the battery
1. Remove the computer from its base.
2. Identify the battery cover, with its deep
slot (a similar battery cover is found on
the back, or skin-side, or the heart rate
strap).
3. Insert a large coin into the slot and rotate
in a counter-clockwise direction about

4. Lift the battery cover, exposing the

Be careful to avoid losing the rubber O-ring
seal.
5. Remove the old battery.
It may be possible to shake the battery out.
Otherwise, carefully pry the battery up with
a thin tool or knife blade.
6. Insert the new battery with the ‘cross’
and identifying label pointing up
(Figure 18).

To measure rollout for wheel size
Table 1 approximates the circumfer-
ence of each tire size. Instead of using
an approximation, you can measure the
actual circumference of your wheel. You
need a helper, your bike, and a smooth
floor with enough room to roll the bike
about 7 feet (245 cm) in a straight line.
1. With the valve stem of the front wheel
directly over the floor Figure 19), sit on
the bike.
Figure ꢀ9- Measuring rollout for
wheel size
2. Have your helper mark the floor at the
valve stem.
3. While you sit on the bike, have the helper roll the bike forward
one revolution of the wheel, so that the valve stem is again
directly over the floor.
4. Mark the new location of the valve stem.
5. Measure the distance between the marks, in millimeters.
If you can only measure in inches, convert to millimeters by multiplying
by 25.4.
6. Use the result to program your computer, following the instruc-
tions on page 22.
