SRAM X0 Typ2 Short Cage Rear Derailleur

The new SRAM XO type 2 10-speed derailleur has compared to the previous version a couple of changes. One of the changes is the so called 'Cage Lock'. By pressing the button it is possible to release the tension of your derailleur, this makes it easier to replace your rear wheel. In addition, the use of the 'Roller Bearing Clutch' ensures your chain is kept under tension. This ensures that 'ghost shifting' and slapping the chain is kept to a minimum.
