Deragliatore Posteriori SRAM XX1 Type 2

Descrizione

The Sram XX1 Type 2.1 rear derailleur has a "horizontal parallelogram" design and the derailleur jockey wheel offset, X-Horizon keeps the chain distance constant across all 11 gears, so you can shift quickly with the Sram XX1 rear derailleur. Equipped with 'Cage-Lock': by pressing the button it is possible to release the tension of the derailleur in order to get the rear wheel easily in and out. In addition, the chain tension is kept much tighter. This ensures that 'ghost shifting' and slapping of the chain is kept to a minimum.
