Shimano's Ultegra Di2 shifters raise the bar for high-speed shifting and unbeatable ergonomics. With a simple push of a button, you get precise, near-instant gear changes. These sculpted beauties greet your hands with a flat transition from the handlebars to the hoods, and the blade design makes it even easier to reach the shift buttons from the hoods or the drops. Easy-to-add satellite shifters (sold separately) can be used for even easier access to the shift buttons from the bar tops or the drops. The use of electronics limit wear and tear on your shifting components, so you'll experience like-new, perfect shifting ride after ride.
