SAfeTy And generAl guIdelIneS  
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.  
Fꢀgure ꢁ- Watch the road when  
rꢀdꢀng.  
Fꢀgure 2- Keep the wꢀre out of  
the spokes

The Trek Incite ACH 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  
2. Insert the handlebar clamp into the back of  
the computer base (Figure 4) and slide it  
towards the front of the 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.

the computer base, aligned along the  
computer base.  
2. Insert two nylon ties through the  
computer base (Figure 6).

Placing the magnet and sensors  
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 configurations: round spokes and flat or  
bladed spokes (Figure 7).  
The cadence sensor, with the wire, mounts  
near the crankset. It must be aligned so that  
the magnet passes within 1-3mm, and in line  
with the small line on the sensor (Figure 8).  
Fꢀgure ꢂ- installꢀng magnet on  
round or oval spokes  
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  
is snug against the spoke.

To install the sensor  
These instructions are written for the  
cadence sensor, which goes on the frame’s  
left chainstay. The instructions apply  
equally to installing the ACH Digital  
cadence sensor or the wheel sensor on the  
fork- where there is no wire on the sensor.  
1.0 -  
3.0mm  
1. Align the sensor with the magnet.  
The magnet must pass across the line on the  
sensor (Figure 9).  
2. Orient the sensor so that the clearance  
between the sensor and the magnet is  
between 1 to 3mm.  
Fꢀgure 9- Magnet alꢀgnment and  
clearance  
The sensor can be rotated around the crank  
about 45 degrees.  
If needed, the sensor and magnet can be moved  
up or down the crank and bike frame to change  
the amount of clearance.  
3. For a wireless sensor, install the rubber  
“foot” in the sensor (Figure 10).  
The ACH Digital has an integrated rubber foot.  
4. Attach the sensor with nylon ties, but  
do not fully tighten.

5. With the computer in the computer base,  
check the alignment of the sensor and magnet  
by spinning the wheel and noting if the  
computer is displaying cadence (or for the  
wheel sensor, speed).  
If the computer shows cadence (RPM) or 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.

length (Figure 11).

POSITIOnIng Of THe HeArT rATe STrAP  
To monitor your pulse, or heart rate, you  
must be wearing the heart rate strap. The  
strap senses each contraction, or beat, of  
your heart. The beat is sensed electrically,  
so proper location of the strap is important  
to attain the strongest signal.  
To be near to your heart, wear the heart  
rate strap around your lower rib cage, just  
under the breasts (Figure 12).  
For best results, the contact between the  
sensor and your skin should be moist.  
Fꢀgure ꢁ2- Posꢀtꢀon of the heart  
rate strap  
Wet the ribbed section of the sensor before  
putting it on. Once you start riding, this  
area will stay moist from perspiration.

Pairing (ACH digital only)  
The ACH Digital computer uses a wireless system where the  
computer reads radio signals from the speed, cadence, or heart  
rate sensors. For the computer to differentiate the signals, the  
computer must be paired to the correct sensor.  
To PAIr the computer  
Only activate one sensor at a time. Until Pairing for a given  
mode (Speed, Cadence, Heart Rate) is completed, the computer  
cannot tell one signal from another.

rePlACIng THe BATTery  
If the computer is giving erratic information,  
a computer or sensor battery may be running  
low on power (normally accompanied by the  
low battery icon, Figure 17). Replace the  
batteries whenever the computer malfunc-  
tions, or every 6 months. Take an old battery  
to the store with you, but this is the generic  
description for the proper battery:  
ACH computer and heart rate strap  
• CR2032, lithium cell, 3 volts  
ACH wheel sensor  
• 23 AE 12v  
Fꢀgure ꢁꢂ- low battery ꢀcon  
ACH Digital- computer, sensors, heart  
rate strap  
• 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. With the ACH Digital, you will have to  
again perform the Pairing procedure.  
Replacing the battery in the speed sensor, cadence sensor, or heart rate strap  
follows the same basic procedure.

To replace the computer 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  
one-quarter turn (Figure 18).  
4. Lift the battery cover, exposing the  
battery.  
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 19).

To measure rollout for wheel size  
Table 1 approximates the circumference of  
each tire size. Instead of using an approxima-  
tion, you can measure the actual circumfer-  
ence 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 22), sit on the bike.  
2. Have your helper mark the floor at the valve  
stem.  
Fꢀgure 22- Measurꢀng rollout for  
wheel sꢀze  
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 25.

Grade describes the steepness of an incline.  
It is a function of altitude gain divided by the  
distance travelled, expressed as a percentage  
(Figure 28). For example, if you gain 6 feet of  
elevation in 100 feet traveled (183cm / 47.2m),  
you would be on a 6% grade.
