Shimano's 105 Dual Control Left-Side Lever (Triple) is for use with a triple crankset and a triple front derailleur. Shimano's Dual Control levers let you shift and brake without ever taking your hands off the handlebars. The short-stroke shifting is so telepathic you'll be in the gear you want almost before you realize you shifted. Plus, the robust design offers excellent durability and the hoods are ergonomically contoured for top comfort.
