SRAM Rival AXS X-SYNC 40T Chainring – Direct Mount Performance Upgrade

Engineered for precision
This direct-mount SRAM Rival AXS chainring delivers seamless integration with compatible electronic drivetrains (11-speed). The 40-tooth design optimizes gear ratios for mixed-terrain cyclists prioritizing torque over cadence—ideal for gravel grinding or technical trail climbs where consistent power delivery matters most.

Built to endure
Forged from aerospace-grade aluminum alloy (6061-T6), this chainring resists metal fatigue while maintaining featherlight performance at just [insert weight] grams. The proprietary X-SYNC tooth profile reduces chain wear by up to 50% compared to standard designs*, ensuring quieter operation and longer component lifespan across XC racing or daily urban commutes.
