Review on RUJOI 160mm Disc Brake Rotor: High Performance, 6-Bolt Design with Brake Pad Adjuster - Ideal for Shimano/Tektro/TRP Brake Lock (2pcs) by George Utley

Mounted on a home built 1500w fast electric bike. Received two in a box, along with a metal spacer and the required number of Loctite coated mounting screws. Works well with a Shimano single cable actuated disc brake caliper and standard polymer brake pads. Erases a very heavily stressed area of the rear axle of the engine. Cooling holes large enough to allow a security lock to be mounted on the drive if required. Brake pressure and feel is almost identical to the old-school V-Brake front I still have to use (with an old Manitou Pro fork, no disc mount). No problem, although sometimes they seem to make a bit of a "ringing" or clinking sound. never mind I'll probably have to do an alcohol cleaning and some other pads when they wear out.
