RUJOI 160mm Bike Disc Brake Rotor Set – Front & Rear Stainless Steel Brake Discs with Calipers & Bolts – MTB Parts for Mountain, Road & Hybrid Bikes

very good

Stops like a power outage

For the price these are a great value. They are solid and are certainly very strong. I haven't actually weighed them, but given the amount of steel they are certainly heavier then some other options. However the brand name options are at least 5x the price!The bolts for these are Torx not hex. That isn't quite common for brake rotors, but it isn't unusual either. No problems there at all. And the set includes a handy little tool to align the brake calipers. Every bike toolbox should have one.

I have both the 180mm (round edge) and the 203mm (wavy edge) in use. Both are great ! The photos show the 203 mm version. Highly recommended. Comes with gap gauge as well.

Bought for an alternate set for my Cannondale Bad Habit Mtn Bike so I can road ride. They don't get much wear like they do on the trails, but they fit, are true (straight) and installed no problem. Metal is a bit thicker than my other discs, but fit in my Shimano XT brakes.

Installed on a DIY build 1500w fast ebike. Received two in the box, along with a metal pad spacing disk and the proper number of loctite coated mounting screws. Works well with a simple Shimano cable actuated disc caliper with stock resin pads. Clears the very busy rear motor axle area. Large enough cooling holes to fit a disk mount security lock if desired. Braking pressure and feel are almost identical to the old school front v-brake I still must run (using an old Manitou Pro suspension fork, no disc mount). No problems, although they do seem to sometimes make a "chiming" or ringing sound a little bit at times...no big deal. I need to do an alcohol clean is all probably, and some different pads once these wear out.
