To Install the Sensor(s)
Certain Trek and Gary Fisher road bikes feature a specially designed pocket
that allows you to integrate a SpeedTrap sensor directly into the fork leg or a
DuoTrap (Figure 32) sensor directly into the chainstay. If installing a SpeedTrap
or DuoTrap sensor (both sold separately), please refer to the installation
instructions included with the sensor.
For non-SpeedTrap or DuoTrap compatible bikes:
Position the sensor on the fork leg (Figure 31) or chainstay to achieve
the correct alignment with the magnet (Figure 28). If needed, move the
magnet.
When you have achieved the correct alignment, pass a zip-tie through the
sensor and around the fork blade or chainstay (Figure 33).
Install a second zip-tie.
Re-check the alignment of the sensor, and tighten both zip-ties.
Using a pair of scissors, cut off the excess length of zip-tie.
