NEW DURA-ACE DELIVERS CONCENTRATION, CONTROL AND CONFIDENCE
The all-new 2013 Dura-Ace group is the result of 40 years of development and innovation, tested to the limit at the highest level of competition in road racing, time trials and cyclo-cross. Dura-Ace now has an 11-speed cassette with numerous gearing options to cover all situations. Leading edge design, materials and construction reduce weight, improve stiffness and enhance control. Every innovation, every detail, has one aim – to give Dura-Ace the power to make you go faster.

Technology
Dura-Ace is Shimano's flagship group, built on many technical innovations. Dura-Ace relies on Shimano's most advanced manufacturing technologies to give class-leading performance for all riders centred on delivering concentration, control and confidence.

Concentration
You are your bike's engine. You need to remain free of distractions. Dura-Ace lets you concentrate on the ride by making shifting and braking as easy as possible. Redesigned shift levers and new smooth polymer coated cables for mechanical Dura-Ace give shorter lever stroke and lower shifting effort for easier, faster shifts. Electronic Dura-Ace Di2 shifters have improved ergonomics and feedback. And a new 11-speed cassette means that you can always find the right gear.

Control
Whether it's the slick, smooth action of mechanical Dura-Ace, the lightning-fast electronic shifting of Dura-Ace Di2 or the improved modulation of symmetrical dual-pivot brakes, Dura-Ace gives you maximum control. The unique needs of road racers, time triallists and multisport athletes are met with a range of shifter and brake options.

Confidence
For maximum performance, you need to have confidence in your equipment. Dura-Ace delivers unparalleled reliability, with a PTFE coated chain and new polymer-coated cables boosting durability as well as giving smoother performance. Dura-Ace Di2's electronic shifting puts effortless and precise shifts just a button push away, regardless of weather conditions. And the new Dura-Ace Hollowtech II crankset with asymmetric spider design guarantees maximum power delivery.
