Performance without compromise Three key words have emerged as the theme for the total new DURA-ACE system: Speed, Smooth and Strength. Speed and Smooth result in effortless shifting, improved braking operation, enhanced ergonomics and updated 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 those three concepts.
