Every detail of the 11-speed X1 X-HORIZONâ„¢ rear derailleur is engineered for smooth, reliable shifting action-from the larger upper pulley offset to the 12-tooth X-SYNCâ„¢ pulley wheels. By eliminating unwanted chain movement, X-HORIZONâ„¢ shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with CAGE LOCKâ„¢ technology, wheel removal and installation are easier than ever.
- This X1 rear derailleur is an integral part of the SRAM 1xâ„¢ drivetrain system. NO COMPROMISES.
- X-HORIZONâ„¢ design reduces shift force and ghost shifting
- Consistent chain gap on all cogs
