Features of the SRAM Apex XPLR rear derailleur

• specifically designed for 1x12-speed drivetrain systems
• suitable for cassettes with 10-44 or 11-44 teeth gradation
• clutch to control the chain tension
• no sudden miss-shifting thanks to X-Horizon™ parallelogram design for less effort and more precise gear changes
• X-Actuation™ technology for crisp, sharp and consistent shifting performance across the entire ratio range of the cassette
• Cage Lock™ mechanism for faster wheel changes and easier chain installation
• for use with mechanical Apex / Eagle shifter levers and Flattop chains

X-Horizon™ | The parallelogram design of X-Horizon™ rear derailleurs limits movement along the horizontal axis. This eliminates so-called "ghost shifting" and reduces the effort required to shift gears. The large offset of the top sprocket ensures constant chain spacing in each gear, allowing faster and more accurate shifting.

Cage Lock™ | Thanks to the Cage Lock™ rear derailleur technology, the installation and removal of the rear wheel and the chain assembly are faster and easier than ever before. Simply slide the cage forward to release the chain tension and lock.
