Shimano Dura-Ace is the cream of road bike groupsets, with the Japanese giant applying its latest technology and most cutting-edge materials to deliver the very best in bike componentry.
Described as their “lightest, most ergonomic, and most precise groupset ever”, it comes in mechanical and electronic Di2 versions, and sits above performance road groupset Ultegra in the Shimano family tree.
With this latest update, Dura-Ace will continue to be available in electronic (Di2) and mechanical options, and both will remain 11-speed. Along similar lines, Dura-Ace Di2 will not be wireless in a traditional sense, although it does feature some wireless functionality.
The latest mechanical version is Dura-Ace 9000, released back in 2013, was described by our tester James Huang as “plain fantastic”, especially when compared to its predecessor.
He particularly liked the fact that shifting is quieter, faster and smoother, while also praising the slight weight savings, improved hood shape and cleaner looks. Read our full review.

So good in fact that our reviewer Ben Delaney says it “underscores mechanical shifting limitations”, like squeezing in shifters where previously you couldn’t, such as aero bar extensions. Read our full review.
