The SRAM Rival 1 Rear Derailleur is engineered for riders seeking smooth, precise, and reliable shifting in demanding conditions. Designed specifically for SRAM’s 1x™ drivetrains, it delivers consistent performance by eliminating unwanted chain movement and reducing shift effort.
Featuring Exact Actuation™ technology, the Rival 1 provides fast and accurate gear changes using SRAM’s 1:1® cable actuation ratio. The X-HORIZON™ straight parallelogram design keeps derailleur movement strictly horizontal, preventing ghost shifts and enhancing shifting precision.
The X-Sync™ pulley with its 12-tooth design controls lateral chain movement, while the Roller Bearing Clutch™ maintains consistent chain tension, reducing chain slap and noise. Cage Lock™ technology simplifies wheel removal and chain installation for quick maintenance.
Built for reliability and efficiency, the Rival 1 accommodates cassettes with sprockets ranging from 36 to 42 teeth, making it ideal for gravel, cyclocross, and performance road cycling.
