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. 

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. 

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. 

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.

This is a great Di2 9150 shift/brake lever, an improvement over the previous version. The click sound from each shift button is louder, and the shift action provides more positive feedback. While not as loud and positive as mechanical SRAM Red, it's close enough. Of course, shifting is smooth and flawless as always. Once you fine tuned it to a particular cassette, it's pretty much set and forget. Highly recommended.
