INSTALLATION
Tools needed:
• Electrical tape
• Slot-type screwdriver
• Phillips-type screwdriver
• Scissors
This section explains the steps to install your computer onto your bicycle:
• Placing the computer on the handlebar
• Placing the magnet and sensor(s) on the bike
Placing the computer on the handlebar
The Trek Incite computer can be mounted on the handlebar or on the stem (Figure
3).
To install the computer on the handlebar
1. Determine your bicycle’s handlebar diameter: 22.2mm, 25.4/26.0mm, or 31.8mm.
2. Select the corresponding bar clamp
For a 22.2mm bar, use the rubber shim (provided) inside the smaller clamp.
3. Insert the handlebar clamp into the back of the computer base (Figure 4) and slide it towards the front of the base.
4. Insert the rubber friction pad into the computer base, aligned across the computer base.
5. With the wire pointing toward the front of the bike, wrap the bar clamp around the handlebar.
6. Insert the screw through the washer and into the computer base.
7. Tighten the screw until the computer base cannot rotate on the handlebar.
8. Slide the computer into the computer base until the front of the computer and computer base line up.
9. 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.
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.
6. Tighten the nylon ties and trim the excess length.

Placing the magnet and sensor(s) on the bike
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).
Computers with the cadence function have two sensors. The shorter computer wire is for the cadence sensor which mounts near the crankset. The sensor must be aligned so that the magnet passes within 1-3mm of the sensor, and in line with the small line on the sensor (Figure 8).

To install the 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 ʻTʼ with the spoke as you slide the magnet up the blade.
3. Thread the screw into the magnet until it is snug against the spoke.

Installation
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 9).
Make sure the computer wire is not pulled tight when the handlebar is turned all the way to either side.
Wireless computers do not have wires. For wireless computers, see To install the sensor.
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.
4. As needed, solidify the wire attachment with either nylon ties or electrical tape.

To install the sensor
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.
1. Align the sensor with the magnet.
The magnet must pass across the line on the sensor (Figure 10).
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 blade or crank about 45 degrees.
If needed, the sensor and magnet can be moved up or down the fork and wheel to change the clearance.
3. For the wireless sensor, install the rubber “foot” in the sensor (Figure 11).
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 speed.
If the computer shows current speed, the sensor is reading the magnet. If the computer is not displaying current speed, realign the sensor and magnet until current speed is displayed.
6. Tighten the nylon ties and trim the excess length (Figure 12).
