The X0 rear derailleur, the main attention was paid to maximum switching speed and precision. The lightweight carbon cage was precisely adapted to the required length for 10x translation. Exact Actuation technology to produce smooth, precise shifts throughout the gear range. The SRAM Type 2.1 derailleurs have improved Roller Bearing Clutch Technology and a Cage Lock. That means in plain language that the cage has a higher voltage power. The chain tension is kept high on rough trails thus, reducing a beating of the chain against the chainstay.
