This Hydraulic Groupset is SO CHEAP!!!
The 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.

Possibly the best value groupset in existence!
The reviewer discusses the LTWOO R9 Disc groupset extensively, highlighting its exceptional value as an alternative to Shimano's 105 groupset. They note it offers hydraulic disc brakes and 11-speed functionality at a fraction of Shimano's price (around £140). The reviewer praises the braking performance as 'absolutely fantastic' and mentions good build quality with features like ceramic brake pistons and replaceable jockey wheels. However, they critique the shifting performance as being slightly inferior to Shimano's, particularly in feel and multi-shift reliability, though this improves significantly when modifying the cable routing. The reviewer concludes it's an excellent value proposition despite minor shortcomings.
