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.
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.
What's New & Benefits
New 11-speed drive train with a range of gearing options for all situations
More compact lever hoods for improved comfort and control
New asymmetric four-arm crankset optimises power delivery
Lighter shifting and braking action thanks to shorter lever throw and new polymer-coated cables and a new PTFE coated chain.
E-tube single-wire connections on Dura-Ace Di2 to simplify installation and give clean looks
More compact battery for Dura-Ace Di2 with internal mounting options
Improved shifting feedback and multiple shifts on Dura-Ace Di2
New range of wheels including deep-section aero rims
Redesigned symmetrical dual-pivot brakes give better power and control
Same bolt circle diameter for compact and traditional double chainsets means that one crankarm fits all chainring size.
The complete group is again more lightweight than before. The total weight of the mechanical Dura-Ace is 1978 grams and the total weight of Dura-Ace Di2 is 1957 (both excluding wiring).
