IIIPRO 6-Bolt Centerlock Ultra-Light Disc Brake Rotor with Heat Dissipation for MTB Road Bike 140mm/160mm High-Performance Brake

“

The new’ish IIIPro floating center lock disc rotors are pretty good. I have them on 3 wheelsets and braking is solid. Just make sure to use a disc rotor truing tool if they’re not straight.

I picked up these iiiPro disc rotors awhile back. They're a few grams heavier than my lightweight Onirii disc rotors I was using, but braking definitely has more bite. I liked them so much, I ordered a second set. Highly recommended!
