ZTTO Bicycle Brake Cooling Disc Floating Ice Rotor For MTB Gravel Road Bike 203mm 180mm 160mm 140mm Cool Down Rotor Vs RT99 RT86

The reviewer discusses replacing their Shimano disc rotors with ZTTO floating ice rotors purchased from AliExpress. They mention the ZTTO rotors look great, have good ratings, and were affordable at approximately 16 euros each with fast delivery. The reviewer notes the packaging lacked sufficient protection, and one disc arrived slightly bent, causing initial brake adjustment difficulties. They compare the ZTTO rotors to Shimano Dura Ace, which are much more expensive (71-86 euros each). The reviewer installed the rotors using adapters for center lock mounts and mentions the weight difference is minimal (33 grams less for the ZTTO pair with adapters).
