Lol those holes are the most retarded pattern imaginable, it's almost funny. imagine the donkey who came up with the design.
They work fine! I double checked my gravel bike brake pads which does long descents on dirt trails and there are no deep track lines on the pads. My 2x160mm rotors are 1.6mm thick and feel quite sturdy. For someone to toast their rotors and dig tracks into their brake pads suggest to me they weighed like 130kg and had zero clue how to feather and modulate front/rear braking! There's a reason they have bigger rotors for bigger riders!
