The SRAM X1 drivetrain carries on the tradition of SRAM’s championship-winning 1x philosophy. X1 excels in several ways. It is simpler, lighter, and the shifting is fast and solid. It is a drivetrain that is free of front shifters, front derailleurs, and extra chainrings. X1 is built to be a dedicated 1x system. Its wide range gearing and quick, snappy shifts are built to excel at everything from elite cross country racing, enduro racing, and high-performance trail riding. No matter where you ride, or what you are up against SRAM X1 is up to the challenge.

With SRAM X1 you not only get 11 speeds, but also a very widespread of cogs that go from 10 to 42 teeth. This large ratio cassette supplies you with all the gear needed to easily spin your way up climbs while still being able to mash your way down hills or along flat sections. The three smallest cogs of the X1 cassette is sculpted from a single piece of steel to create a lightweight and durable cassette that when combined with the XD driver body creates a superior connection to the wheel.

The X1 trigger shifter is an integral part of the SRAM 1x drivetrain system. Built to be simpler, lighter, and more durable the SRAM X1 X-Actuation trigger shifter keeps gear changes sharp and consistent across the entire 10 to 42-tooth cassette.

With its “horizontal parallelogram” design and pulley offset, X-Horizon 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. Roller Bearing Clutch technology reduces bounce and chain slap. Cage Lock technology makes wheel removal and installation easier than ever before. Paired with the X1 shifter, the X-Horizon rear derailleur forms the backbone of X-actuation technology for unbelievably smooth shifting action.
