Review on Bicycle Disc Brake Rotor Set: High-Quality 160mm/180mm Bike Disc Brake Rotors with Bolts for MTB & Road Bikes by Marco Maurer

I bought these for my 9 year old daughter's new build. I can't believe they can make rotors and ship them to your door at this price point. I thought they were crappy or wobbly but they were straight and looked great. I'm not sure I would ride them as an adult mountain biker, but for a kid or for light use I think they're an amazing price. Update: After a few rides, I rode her bike around the property and the brakes were pounding. . I didn't notice it when the brake pads were new because they haven't held up that well. Now you can feel the uneven thickness of the rotors when braking. I'm adjusting my rating to 3 launches because they're still amazingly cheap and most kids probably won't notice anyway.
