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 brand new CN-HG600 11-speed chain bursts on the scene with an asymmetric design that features outboard plates that aid in front shifting and inboard plates that help to improve rear shifting. This design is borrowed from 105's relative, the HG-X 10 speed mountain chain. The HG-X has proven to offer more accurate, quieter shifting that ever before and these benefits have now been passed on to Shimano's road category. Quiet performance, hassle-free shifting, just set it and forget it, it's everything you want in a chain.
