The SRAM Schaltwerk X-Horizon X.0 1 Type 2.1 rear derailleur is designed for riders who demand crisp, reliable shifting on aggressive terrain. Built around SRAM’s X-Horizon architecture, it keeps the distance between the upper pulley and cassette consistent across the gear range, helping to deliver precise shifts and reduce ghost shifting on rough trails. This makes it an excellent choice for modern 1x drivetrains where chain control and fast, accurate shifting are essential.
Featuring SRAM’s Type 2.1 clutch technology, this derailleur helps keep the chain tight and quiet, minimizing chain slap and the risk of dropped chains when the trail gets rough. The robust construction is aimed at mountain bikers who ride hard and need components that can withstand repeated impacts, mud, and dust. At the same time, the X.0 series is known for combining durability with a relatively low weight, making it suitable for both trail and enduro use, as well as performance-oriented XC riders.
With its straightforward setup and compatibility with SRAM’s matching shifters and cassettes, the X-Horizon X.0 1 Type 2.1 rear derailleur is a strong upgrade for riders looking to sharpen their drivetrain performance. Whether you are pushing through technical climbs, sprinting out of corners, or descending rock-strewn lines, this derailleur is engineered to keep your shifting smooth, consistent, and dependable ride after ride.
