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. 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
