Know before you buy
This derailleur is compatible with any SRAM shifter that utilizes Exact Actuation technology. It will not work with non-SRAM shifters or SRAM road-specific 10-speed systems.
The cage length you choose depends on your drivetrain's total chain wrap capacity. Generally, a longer cage is required for setups with a wider range of gears, while shorter cages are used for tighter, more performance-oriented gearing.
The SRAM GX 10-speed rear derailleur is designed to work with a largest cog capacity of 36 teeth. Using a cassette larger than this may result in poor shifting performance and potential damage to the derailleur.
The Roller Bearing Clutch provides constant tension on the chain, which significantly reduces chain slap and prevents the chain from dropping on rough terrain. It keeps your drivetrain stable and quiet, even when riding over technical obstacles.
No, this specific model is designed for a standard 10x1 mount. Please ensure your frame is compatible with this standard before purchasing.
