Es gibt (oder gab bei älteren) quarks Probleme.
z.B. hier nachzulesen

Danke. Und ich habe auch noch folgendes gelesen:

Unusually high or low power values

Perform the Manual Zero as described in the Quarq Power Meter User Manual.
If the Manual Zero is well outside +/- 1000, check pre- and post-ride Zero Offset values.
If the pre- and post-ride Zero Offset values differ by more than 50 points, it may be necessary to contact Customer Support. Keeping a record of the Zero Offset values will be helpful when contacting Customer Support.

With a new power meter or newly installed chainrings, the zero offset takes 2-3 rides to stabilize. During this time you should perform the Manual Zero procedure regularly to ensure accurate power readings. Short, hard efforts in both chainrings on your first ride will speed up stabilization.

Remove third party cadence sensors. The power meter delivers both power and cadence data to the bike computer.

Inspect and clean the chainrings and power meter, including the chainring mounting tabs. Re-assemble according to the instructions in the Quarq Power Meter User Manual.

Ich habe noch den 2. Cadence Sensor dran. Der muss also auch noch runter. (Wieder 10g gespart :-) )
