D Dymoece 2 Pcs Bike Disc Brake Rotors with 12 Bolts 140mm/160mm/180mm/203mm for MTB Mountain Road Bicycle

These rotors have play at the screws because the holes are measured wider than the screws. Which caused these rotors to shift under braking. My solution was to loosen up the screws and twist the rotors in the direction they would move under forward breaking as far as possible then tightening the screws down. This solved the rotors shifting problem.

Took a bit longer than usual receiving the package. I used Amazon prime thinking I would get it faster. Anyway, set up was a breeze. Test rode it only once. I wanted a stronger stopping power for my converted fat bike to a class 3 e-bike. The original came with a 160, figure changing the disc to a larger 203mm one is the least expensive way instead of purchasing a 4 piston brakes.It did the job. Rode for about 20 miles, pushing the bike to go up to 28mph then stopping. No squeak or noise. Couldn't tell you about heating issue because it was cold, about 38 degrees F. First impression so far it's good value for the size and style.

Works great on my escooter, awesome upgrade over the stock rotors. Looks way better too.

These seem to be decent rotors for my older mtb. I have done a brake conversion to an 08 iron horse hard tail from v-brakes to cable pull disc. The front already had the lugs for mounting a caliper but I had to get an adapter for the rear. Once I got the calipers installed loosely I bolted these to the new set of wheels I had to also buy for the conversion. Once they were on the hubs securely I tightened the calipers while I was holding the brake lever on, adjusted and tightened the cable and these are pretty good rotors. They have already taken some abuse off road and haven't bent or broken and they stop the bike really well compared to the old v-brakes did, they are good in my book.

Super light rotors with good braking pad area. Most lightweight rotors there is not enough material to stop bike. These rotor perform on par with brand name rotors
