SRAM's RED shifters are in a class all by themselves. Utilizing SRAM's Double Tap Shifting technology, this is the lightest and most efficient road shift/brake lever ever made. The Red shifters offer a trim function to optimize chain ring selection, not on the Rival and Force models, and also includes double hidden cable routing. Simply put, the SRAM RED shifters deliver fast and precise shifts at a weight that is near unbelievable (280 grams). Includes cables and housing.
