1. Temporarily attach the sensor to the left chain stay.

(1) Loosen the sensor screw using a Phillips screwdriver and check that the sensor arm moves.

(2) Attach the sensor rubber pad to the sensor.

(3) Refer to the illustration and temporarily attach the sensor to the left chain stay with nylon ties.

2. Temporarily attach the magnet.

(1) Using a nylon tie, temporarily attach the cadence magnet to the inside of the left crank arm so that it faces the cadence sensor zone.

(2) Rotate the sensor arm and temporarily attach the wheel magnet to a spoke facing the speed sensor zone.

* If the sensor cannot is not positioned so that both magnets (speed and cadence) pass through their respective sensor zones, reposition the sensor and the magnets so that each magnet passes through its sensor zone.

3. Adjust the gap between the sensor zone and the magnet.

(1) Tilt the sensor so that the gap between the cadence magnet and the cadence sensor zone is approximately 3 mm, then fasten the sensor securely with nylon ties.

(2) Rotate the sensor arm so that the gap between the wheel magnet and the speed sensor zone is approximately 3 mm, then tighten the sensor screw securely.

4. Secure all parts.

Tighten the sensor's nylon ties, the sensor screw, and the magnets, and check that they are not loose.

Trim off the excess nylon tie.

* If using pedals with steel axles, the cadence magnet can be attached magnetically to the pedal axle. In this case, remove the adhesive tape from the magnet and do not use the nylon tie.
