SRAM X-Sync Road Chainring: Precision-Engineered Power Transfer

Optimized for AXS E-Bike Cranksets | 42T Single Ring | 12-Speed Compatible

Built for cyclists demanding seamless gear transitions and unwavering drivetrain stability on mixed terrains. The X-Sync Road Chainring combines advanced tooth geometry with military-grade durability to elevate road riding performance.

Performance Enhancements

• X-SYNC Dual Tooth Profile: Aggressive chain retention on climbs (up to 30% better bite than standard chainrings) paired with smooth engagement on descents
• X-Range Gearing Integration: Perfectly complements SRAM AXS systems for 500%+ gear range progression without cog clutter
• 107mm BCD Compatibility: Direct bolt-on fitment for Praxis Powerlink and Shimano Hollowtech II cranksets

Durability Redefined

Precision laser-engraved surface withstands 500+ hours of training rides while resisting micro-fractures common in cast aluminum rings. Tested under ISO 6336 fatigue standards to endure repetitive torque loads typical in criterium racing or century rides.

Quick-Change System

Patented single-tool installation system reduces crankset rebuild time by 40% compared to traditional multi-tool setups – ideal for time-crunched racers or touring cyclists needing rapid gearing adjustments.

*Based on SRAM internal testing vs leading competitors’ OEM models

Ideal For: Competitive road cyclists (cat 3+), gravel endurance riders (≤28c tires), and e-road commuters needing reliable power transfer in variable conditions (tested from -10°C winter training to +40°C desert stages).
