Shimano Ultegra 6800 Mid-Compact Crank 170 mm (36/52) Presenting Shimano’s new Ultegra 6800 group set. The Ultegra series is performance proven mechanical group as it is a direct trickle down from Shimano’s Dura Ace group. Following the Dura Ace’s move to 11 speed, Shimano has introduced 11 speed to the Ultegra. This performance group set now features an 11-speed cassette with more gearing options. Shimano also claims the new shifter’s ergonomic design greatly resembles those of the new Dura-Ace. According to Shimano, a complete group weighs 2,309 grams, 35 grams less than the previous generation.
