Review on 🚴 BlueSunshine MTB BB7 Mechanical Disc Brake Set with 160mm Rotors, Bolts, and Cable - Front and Rear for Increased Performance by Dennis Wood

The calipers are easy to install and fairly easy to adjust. The problem is the rotors themselves. Wouldn't stop at all, I mean it's at least 4x longer than my other bike and can't even lock up the rear wheel. I took the front rim and rotor off another bike and they are holding up just as well as the other bike. I think they tried to overdo it and removed all the slotted and jagged braking surfaces. My other rotors have a very small shell on the OD and just holes instead of slots. There will be different rotors.
