RACEWORK Carbon Fiber Bike Disc Brake Rotor MTB Road Bicycle Ultralight 6 Bolts Floating Rotor 140mm 160mm 180mm Brake Disc

The reviewer discusses the RACEWORK carbon fiber disc brake rotors, noting they are similar to more expensive Carbon TI rotors but much cheaper. They highlight the construction with a steel brake track, carbon spider, and steel rivets, and mention the weight of 89g for a 160mm rotor. The reviewer prefers these over lighter rotors because the brake track is more substantial, reducing heat buildup and brake fade on descents. They also note that the rotors are six-bolt and require adapters for center lock wheels, and they recommend pairing them with lightweight adapters for weight savings.
