Elegant and secure direct-mount X-SYNC chainrings from the company that originated the 1x drivetrain for the ultimate in consistent chain control over the long haul.
SRAM designed X-SYNC chainrings to prevent chain deraillment over bumpy terrain by using both sharp and narrow teeth, as well as rounded chamfer edges.
In addition, the longer DUB crank spindle accommodates both road and MTB width frame bottom bracket standards for unmatched cross-compatibility across brands.
