Sram:

A single chainring with a wide-range cassette is a wonderfully clean way to tackle so many disciplines, and were the 1x leaders. Gravel, TT, tri or crits: just pick the right chainring size for the discipline and go. Our lightweight and strong direct mount chainrings feature X-SYNC tooth technology to maximize chain retention, and they bolt to carbon arms with a spectacular but subtle finish.

FEATURES

• Single-ring drivetrain simplifies functionality and reduces weight
• Direct mount chainrings are lighter and stiffer than traditional spider-based rings
• 48T and 50T variants have direct mount aero chainrings for better aerodynamics
• SRAM X-SYNC wide-tooth, narrow-tooth chainring technology provides maximum chain control
• DUB bottom bracket adds durability and simplicity
• Can be upgraded to a power meter
