SRAM's X7 Front Derailleur is stiff, light and strong. It provides crisp, precise action for fast, smooth and reliable shifting season in and season out.
Your seat-tube diameter determines the needed derailleur clamp size.
Capacity is calculated by subtracting your smallest chainring's tooth count from the largest chainring's tooth count. Example: 46/34/24 chainrings: 46 - 24 = 22-tooth capacity.
Maximum chainring size: 42 teeth
