The Shimano 105 5800 groupset has been revamped for 2014/15. Now in 11 speed, these components draw down technology from the Shimano Dura-Ace and Ultegra groupsets.
Shimano 105 5800 STI levers, feature ergonomically designed 11 speed 105 dual control levers. These levers come complete Polymer coated cables and silicon greased outer casing. The calipers feature Dual pivot technology and are the racer's choice. They are compact and have a lightweight design for high performance. The Shimano 105 front derailleur has a wide link design for increased rigidity and improved shifting response. The Shimano 105 5800 rear derailleur gives awesome shifting under all conditions. Increase rigidity and reliable long term quality with this 11 speed 105 wide link short cage rear derailleur. The Shimano 105 cassette is a high performance road cassette with hyperglide EV sprockets that have a computer designed tooth configuration. These have contoured shift gates, resulting in a crisp smooth shift even under load. The 11-speed chain uses previous years Dura Ace technology and Shimano's low friction surface treatment SIL-TEC, to reduce friction.
A groupset is a matched set of components from a single manufacturer that are designed to work well together. If you are upgrading your existing bike or specifying a new one, you can usually save money by buying a groupset rather than the individual parts. Pay close attention to whether all the parts will fit your frame - particularly the front derailleur. Most groupsets don't include hubs or pedals but there are many different configurations so read the component list carefully.
