Burke 20 - SRAM XX1

6,500.00

The XX1 group is SRAM's top-of-the-line 1x11 drivetrain. Single chainring drivetrain simplifies functionality.

The XX1 cassette is SRAM's X-Dome 10-42t wonder. This 11-speed cassette gives an amazing 420% gear range without sacrificing clean shifting or speed. The gearing is equally spaced so that there aren't any surprise jumps in cadence or missed gears.

The Force 1 crankset combines SRAM’s Force 22 carbon arms and forged aluminum spider with SRAM’s world-class 1x11 MTB technologies. Featuring X-SYNC™ technology, the Force 1 crankset is engineered for complete chain control. Unidirectional carbon in crank arm is matched to a forged alloy spider for light weight and durability.

The shifter features a carbon fiber body and lever for lightweight, durable construction. The shifter also uses X-Actuation to provide consistent shifting throughout a wide range of gears. 

The XX1 X-HORIZON™ rear derailleur keeps the chain gap constant across all 11 gears, providing fast, precise shifts. By limiting all movement to the horizontal axis, this design is faster, reduces shift force and eliminates ghost shifting.

Weight of bike: ~ 7.9 kg (17.4 lb) without saddle
