r1 racing brake set including spare extra caliper from previous warranty replacement, rotors, extra hose, SRAM matchmaker clamp and extra lever body. These brakes have been amazing, love the modulation and stopping power and also easy to maintain. The front is bled but have had to cut the back to get it off the bike they were on. Super light at around 360g on my scales for the set without rotors. Recently had fresh pads so loads of life left
