LTWOO RX / R9 Disc 2x12s / 2x11s Road Hydraulic Disc Brake Groupset, 6 kit, Benchmark R7170 R8170
Created: September 20, 2024The reviewer discusses the LTWOO R9 2x11 speed hydraulic disc brake groupset used in a gravel bike build for their son. They mention it's their first time using a budget Chinese groupset from LTWOO and their first experience with hydraulic disc brakes. The groupset arrived well-packed without its original box (a cost-saving measure), and includes shifters, front/rear derailleurs, brake calipers, and hoses. The reviewer notes the brakes came pre-filled with mineral oil and had hoses already terminated into the calipers. Installation required some adjustments, particularly with the shifter mounting screws being awkwardly placed behind the hoods. The reviewer successfully installed and bled the brakes, finding the process less difficult than anticipated.
