Narrow-wide tooth profiles solved the chain retention problem that plagued early 1x drivetrains, and the Force 1 X-Sync chainring applies SRAM's tooth design to their road-focused single-ring systems. Each tooth alternates between wide and narrow profiles that match the inner and outer chain link spacing, creating a mechanical grip that holds the chain in place without the weight or complexity of a chain guide. The design works particularly well on rough pavement, gravel, and cyclocross courses where impacts and vibration would otherwise bounce a chain off a traditional ring.

The chainring mounts directly to Force 1 cranks using SRAM's hidden bolt pattern with a 110mm BCD. This direct-mount interface positions the ring closer to the crank spider than traditional bolt-on designs, which improves chainline and shifts the ring inboard slightly compared to the outer position on a double crankset. The aluminum construction uses CNC machining to cut each tooth profile precisely, which matters because the retention system depends on tight tolerances between the tooth shapes and chain plates.

Tooth count options run from 38T through 46T in two-tooth increments, letting you match the ring to your terrain and fitness. A 38T pairs well with a wide-range cassette for hilly routes or mixed-surface riding, while the 46T suits flatter terrain where you want higher gearing without sacrificing the simplicity of a single ring up front. The black anodized finish matches Force 1 cranks and resists corrosion from road spray and sweat.... Read More
