Shimano Ultegra 6800 11 Speed Groupset

The Ultegra 6800 series is "pro-proven" as it is a direct trickle down from the Shimano Dura Ace groupset. It stands for state-of-the-art technology, proven in pro races, the technology used in the new Ultegra 6800 series with 11 speed, newly designed

brakes, new chain treatment etc.
