Just when you thought shifting quality and reliability couldn't get any better, Shimano ups the ante with their Dura-Ace Di2 9070 electronic components. Some call the Dura-Ace Di2 9070 a "luxury group", but we have yet to meet a pro who didn't want ultra-reliable, precise, lightning-fast shifts across an 11-speed cassette with just a button click.
This build kit includes everything needed to build a complete bike except frame, fork and pedals. The crankset gets and new bolt diameter that will house compact, mid-compact and standard size chainrings. While they are at it, they decided to offer more front chainring options. The brake set now works on a cam, so the modulation is improved and the braking power is increased. The front derailleur has a longer pivot arm that makes front shifting so smooth, it rivals electronic shifting. The dual controls brake/shift levers receive improved ergonomics and smoother cable routing. Simply put, this is the best Dura-Ace release to date and possible the best set of bicycle components ever produced.
A Ritchey WCS cockpit and Mavic Aksium wheels round out the package.

Please call 800-627-6664 to order with our helpful sales staff or if ordering online include the following specs in the comments section of your order. It is helpful to know where the battery is designed to be located on your frame, where you plan to locate the lower junction box (internal or external on the bb cable guide area) and if your frame is factory designed for Di2 internal routing. If possible, also measure from the lower Junction Box to rear derailleur, front derailleur, battery and Cockpit Junction to determine E-tube wire lengths.
