The new Ultegra 6800 groupsets features a redesigned 4 arm chainset that allows 34/50 and 39/53 rings combinations to be used on the same spider, we will also see the 36/52 ratio as seen on the Dura Ace chainset. The brake calipers are symmetrical dual pivot design again brought over from the 900 Dura Ace groupset, 10% more powerful than the 6700 caliper.
The rear derailleur has a GS model to allow it to be used with the 6800 11 speed 11-32 cassette, when used with the compact chainset it gives a gear for every ride and every rider, ideal for the toughest sportives.
