MAHLE 12-Speed Magnetic Ring
Couldn't load pickup availability
The MAHLE magnetic lockring for 12-speed cassettes secures the freewheel and transmits the signal to the PAS sensor, which detects pedalling. It must be fitted to the X20 or X35 system, where it detects pedal movement. If you are looking for a lockring for your e-bike with a 12-speed cassette, this is the right version.
It weighs 84 g and fits on the cassette side of the rear wheel. Choose this version only if the cassette is 12-speed: compatibility is not guaranteed for other speed counts. Also check that the freewheel is compatible with the lockring before fitting.
