Review on 2Pcs 160Mm 180Mm 203Mm 6-Bolt Disc Brake Rotor Stainless Steel Bicycle MTB BMX Road Bike by Phillip Samuel

The disk seemed fine when new. However shortly after installing them, I noticed that the rotor on the rear wheel of my E-bike was vibrating. It took some time to confirm the vibration was coming from the rotors and not something else. I was able to dampen the vibration by using electrical tape between the ribs of the rotor. It was annoying that I had to do this to reduce the noise, but acceptable.However, I have recently noticed that the front rotor is beginning to rust after only 8 months of usage. And I happen to live in a pretty dry environment.If you are willing to live with these issues, then the price for these rotors is good. If not, then you might what to spend a little more for better quality rotors. I would recommend something without long spiny ribs for use on an E-bike if you want to minimize vibration noise.
