What Our Gearhead® Experts Are Saying: "I switched to the 40T X-SYNC for a simplified 1x road setup—it’s light, silent, and holds the chain even over rough pavement. Pair it with a wide-range cassette and it’s the perfect gear for rolling routes and mixed-surface riding."When we crave the simplicity and dependability of a 1x drivetrain, the SRAM X-SYNC Road 40T 110BCD Chainring delivers crisp engagement and worry-free chain retention. Its tall, square-edged tooth profile grips every link securely, so we can sprint, descend, and hammer through chip-sealed climbs without dropping a chain. CNC-machined from aluminum for minimal weight and maximum stiffness, this chainring balances road efficiency with off-pavement confidence. The 40T size offers the ideal middle ground for all-round road and gravel riding—keeping cadence smooth and shifting transitions clean. Whether mounted on a lightweight commuter or a race-tuned gravel rig, the X-SYNC 40T brings the precision of SRAM’s mountain-proven technology to the tarmac.
