L TWOO RX Hydraulic Groupset: We have a problem (Or two)
00:28:10

The reviewer discusses the LTWOO RX 12 Disc 2x12s Road Hydraulic Disc Brake Groupset extensively throughout the video. They mention that the group set is close to being great but has some issues. The shifting is described as perfect, with crisp and reliable performance, but the brake lever travel is initially too long, making braking feel spongy and less effective, especially in the drops. The reviewer later discovers an adjustment screw that fixes the brake lever issue, significantly improving performance. They also note that the group set does not come with rotors, which causes compatibility issues with Shimano rotors. The reviewer highlights the lack of instructions as a major drawback but ultimately finds the group set to be a promising, affordable option once adjusted properly.
