Setting a new bar in the trickle-down technology trend, Shimano 105 5800 brings uncompromising 11-speed road performance to the more budget conscious rider. With a foundation set firmly on the success of Dura-Ace and Ultegra, Shimano's 105 5800 group is a workhorse component package that can hang with the best the industry has to offer. Powerful improvements across the range deliver optimized drivetrain and braking performance that will instantly take your riding to a whole new level. There are lots of flashy, distracting contenders out there, but if you're main focus is getting down to business, the new Shimano 105 group is ready to log some overtime.
Shimano's 105 ST-5800 11 speed shifters borrow from their older siblings in all the right places. That famous light-action shifting that creeped its way down from Dura-Ace to Ultegra has now found its way to the 105 series. The ST-5800 shifter features an ergonomic compact lever shape with shift action that has been optimized to deliver what Shimano calls "the lightest and easiest front shifting Shimano has ever made." The crisp, responsive shifting that made Shimano famous and used to be financially out of reach is now at the fingertips of the masses.
