The Shimano 105 ST-5800 Shifters are some of the best value shifters available on the market today, featuring trickle-down technologies from Shimano's Dura-Ace and Ultegra lines at a reasonable price. One of those trickle-down technologies is the redesign of the brake levers to make braking more comfortable when your hands are on top of the shifter hoods. The 105 ST-5800 Shifters also feature an internal cable routing to help give them a more aerodynamic design so nothing will slow you down during your rides. To help make these shifters light and durable, Shimano has crafted the levers out of aluminum, which adds only a small amount of weight. Shimano has given these levers a silver finish as the finishing touch. The Shimano 105 ST-5800 Shifters are designed to work with Shimano 10 speed double drivetrains. Includes shifter cables.
