Can anyone tell me if Magura Louise rotors are compatible with SRAM brakes?

If the size is correct a rotor is a rotor is a rotor.

Wish the above was true, the biggest issue is having the rotor braking surface cover the pad, not sure if the Louise brake pads are the same size as SRAM, a visual check of the rotors should tell you.

Magura rotors are made by galfer so are 2mm thick from new unlike SRAM Shimano which are 1.8 mm and you’ll be having superb initial bite point but the brakes will drag\rub slightly
So no a rotor isn’t a rotor as mentioned above .

Yeah, as stated, as well as thickness it’s the actual rotor/brake pad contact zone that is the critical part, i honestly do wish they were all interchangeable, was thinking of shifting to hopes on the enduro, but shimano and hope don’t mix, so it would be another 80 or 90 quid on rotors.
