Does anyone know where to purchase disc rotors with the integrated speed sensor that come oem on the PX? ( they are not an option in the accessories section of the Amflow website)?

Whole idea is to remain with 2.5mm rotor and not have extra distance from added sensor. I can’t find them on the Magura site either ( Amflow specific that is)
These are the 2.5mm rotors.
MDR-S 2.5 - MAGURA Bicycle Brakes & Spare Parts
The new MAGURA MDR-S vibrates Thanks to an optimised friction ring design and the increased rigidity of a 2.5 mm rotor.
magura.com
Which can be combined with this:
DJI Avinox M1 Speed Sensor Ring - 42 Teeth | eBike24
DJI Avinox M1 Speed Sensor Ring - 42 Teeth ▶ Regulates Maximum Speed | Mounted on Rear Brake Disc ▶ Original DJI Avinox Spare Part ▶ Buy Now Online!

It goes on the outside face of the disc.
Rotor mount (6-bolt) is not the same as rotor thickness.
As others have said, get a speed sensor and use regular MDR-S rotor

I was wondering this too in case I don't like the Maguras. So if you add the separate sensor ring the extra 1mm or whatever it moves it closer to the rear triangle frame doesn't matter I assume?

I've asked Amflow and Magura about getting more of these rotors and neither one can supply me. Magura say they don't sell them, telling me:
"Unfortunately Magura doesn't offer a rotor with a speed ring for the Avinox DJI, in the aftermarket."
And advising me to contact Avinox or the shop where I purchased the bike.
And Amflow don't currently offer them as spares either.
For now I've used my front PX rotor on a new rear wheel and purchased 2x standard rotors for my front wheels.

The bike comes with spacers for the sensor, so you can adjust the distance slightly. Can't remember exactly how much, sorry.

Amflow seem to be a victim of their own success. Every single item on their spares and accessories page shows as sold out. Everything!
Sensor goes on top of the rotor
