DESCRIPTION
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 centered 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.
Improvements:
- 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

of the mechanical Dura-Ace is 1978 grams and the total weight of
Dura-Ace Di2 is 1957 (both excluding wiring)
