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.
For the 5800 series, Shimano didn't only focus on shifting improvements. The 5800 group now offers the same symmetrical dual pivot design found in the Ultegra and Dura Ace groups. Twin bearings at the pivots decrease friction and make for an exceptional brake feel and performance. These updates result in a 10% power increase and the new design allows for up to 28mm high volume tires.
