INSTALLATION

MAGNET INSTALLATION

Quarq power meters measure cadence using a magnet, or if a magnet is not present, by using an accelerometer

that is built into the power meter.

Using a magnet is the best method for measuring cadence; it is accurate to +/- 1.5% regardless of environmental

conditions. When properly installed, the magnet should be in line with the cadence sensors and within 2-8 mm

of the sensor ring. If necessary, magnets may be stacked to achieve the proper distance to the sensor.

NOTICE

Do not allow the magnet to contact the power meter.

If the magnet becomes dislodged or is removed, the built in accelerometer is automatically enabled.

Using the accelerometer to measure cadence offers the convenience of not having to install a magnet. The

accelerometer was specically developed for bikes that have limited options for magnet placement. While the

magnet provides the most accurate cadence measurement, the accuracy of the accelerometer is excellent up to

160 rpm and in all environmental conditions except those that produce severe vibrations.

It is easier to install the magnet when the cranks are not installed on the frame.
