Um.... XT lever, SD7 arms, Clark cable, Heatsink CNC backings, Phatpad material, Shimano Carbon booster. I expect it'll work like poo, due to the rim being covered in bits of paint, but with a fresh grind on it's pretty monstrous. Most would disagree - but I like it. If you pull it hard, it locks, but up until that point there's f**king LOADS of modulation.
