Three key words have emerged as the theme for the latest DURA-ACE system: Speed, Smooth and Strength.
Speed and Smooth result in effortless shifting, improved braking operation, enhanced ergonomics and an attractive feeling and design. Strength is focused on the critical need for lightweight without sacrificing rigidity, durability or precision. "100% Power Transmission" is the goal pursued by the fusion of these three concepts. 
Lance Armstrong used Dura-Ace to win the Tour de France seven consecutive times.



Group includes: STI shifters, crank, bb, front & rear derailleur, chain, cassette and front & rear brakes.
