My rear pads turned to dust the first week. Luna didn’t have any in stock so refunded me $20 almost instantly. Since then I’ve upgraded to magura mt5 that I found for $80/each from starbike.... literally night and day performance contrast over stock. I really have to be careful to not lock up (while my muscle memory gets used to it) and I’m a 1-finger-on-the-brakes rider.
For those of you sticking with stock breaks, I found the avid pads for less than $1 each on AliExpress (I had to hit one corner with the grinding wheel for them to seat flush but works).
