Ultegra is Shimano’s high-end, road- or race-ready mechanical groupset, and has long offered maximum performance for a bargain. But this isn’t just a new set of stickers on the 6700 groupset. Just as Dura-Ace was redesigned for the 9000 series, Ultegra has been tweaked to mimic its higher-end counterpart.
Ultegra 6800 levers feature a refined hood shape, borrowed directly from Dura-Ace 9000, which, in turn, borrow from the venerable Di2 levers. The new design improves grip and comfort, combined with crisper shifting. Sleek carbon lever feature a more pronounced outward curve than on the old 6700, making for a more pronounced interaction with your hands from either the hoods or drops.
The new front derailleur matches the new shorter stroke lever action of the shifters. To achieve this, Shimano had to borrow yet again from Dura-Ace. In a similar manner, the rear derailleur was redesigned to be more compact, lightweight, and to ensure equal shifts across the cassette's entire 11-speed range. The new 6800 was designed with the same attention to the shorter stroke at the lever as Dura-Ace.
Although the first thing you see will probably be the shifters, the 6800 crankset really steals the show. Borrowing from Dura-Ace yet again, the new crankset is practically unrecognizable when compared to the 5700. The 5-arm spider lost an arm, replaced by a 4-arm crankset that not only matches the rigidity of Dura-Ace while saving 26 grams of weight but is compatible with both standard and compact chainrings. Gone are the days of needing two sets of cranks for two sets of chainrings.
Finally, the 6800 brakeset has gotten its own makeover and taken stopping power to a whole new level. Shimano began the redesign from the ground up, using a dual-pivot design, so the mounting bolt is no longer also the pivot. As a result, the brake arms are now located symmetrically over the wheel and work independent of the mounting. The cable stop is still to the side, but the new dual-pivot design allows any pull to apply equal tension to both arms. In addition, the arm placement is closer to the rim, which, coupled with the equal pull, drastically increases modulation.
