Speed Sensor (slim)
The speed sensor(1) and its CenterLock magnet(3)
or spoke magnet(2) are mounted ex works in such a
manner that the magnet, after a turn of the wheel,
moves past the speed sensor with a clearance of at
least 2mm, yet no more than 15mm.
The correct distance between the magnet and sensor
must be maintained (see figureA) if design changes
are made.
Notes: Ensure that you do not damage the sensor or
sensor bracket when fitting or removing the rear
wheel.
When changing a wheel, make sure that the sensor
cable is routed so that it is not under tension and has
no kinks.
The CenterLock magnet(3) can only be removed and
reinserted up to five times.
Rim magnet
When installing a rim magnet, no sensor is required to
detect a wheel turn. The drive unit itself detects when
the magnet is close to it and calculates the speed and
any other data required from the frequency of the
emergence of the magnet field.
Since the drive unit is sensitive to magnetic fields,
avoid other magnetic fields in the vicinity of the drive
unit (e.g. magnetic clipless pedals, magnetic cadence
sensors, etc.) in order to prevent disruption to the
drive unit.
