Sram XX1 11 Speed Rear Derailleur

THE ONE AND ONLY. SRAM XX1 was designed with a philosophy of 1X dedicated transmission: to be simpler, lighter and more durable than any other. Wherever you go, whatever you do: SRAM XX1 IS UNSTOPPABLE. MAXIMUM IMPACT With its design “horizontal parallelogram” and the spacing of the wheel that characterizes X-HORIZON u2122 maintains constant blur chain in 11 speeds, offering fast and accurate changes speeds. By restricting all movements to the horizontal axis, this design offers greater speed, reduces power shifting and eliminates the problem of involuntary changes speeds. The ROLLER BEARING CLUTCH u2122 technology reduces the rebound and prevents the chain gets too often. CAGE LOCK u2122 technology makes it easier than ever removing and installing wheels. Associated lever XX1 speeds, the rear derailleur X-HORIZON is the central element of the X-ACTUATION u2122 technology for incredibly smooth shifting. The wide spacing of the upper roller automatically adjusts the chain gap The right parallelogram design with a horizontal movement reduces the force and improves shifting performance of the transmission Rollers X-SYNC 12 teeth (1 tooth 2 is square) Technologies TYPE 2.1 : ROLLER BEARING CLUTCH LOCK u2122 and CAGE u2122 New pebble silent teeth Weight checked Alltricks: 244 g
