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).

To install the sensor

1.Align the sensor with the magnet.

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
