So I’ve haven’t been running these long but so far really impressed. While I didn’t notice a ton of modulation, they have a gradual increase in braking with enough power that I was able to one finger take without any hand fatigue. For the price I can’t think of a better option out there.
I like these rotors. They're not too expensive and seem to have more bite than the lower end stamped models like SM-RT54. Maybe that's just in my head, but they look nice too.
