First Look: Shimano Di2 Dura-Ace and Ultegra groupsets - the end of mechanical Ultegra

It’s hardly a shock that Shimano has today officially unveiled its latest Dura-Ace Di2 flagship electronic road groupset with a 12-speed cassette and semi-wireless format. We’ve been expecting it for months, and there’s been no shortage of spy photos circulating online. But what few people expected is that — for the first time ever — Shimano has simultaneously launched the new Ultegra Di2 groupset, with all the same features and benefits. What features and benefits, you ask? According to Shimano, the shifting is faster across the board, the brakes run quieter and offer better modulation and feel, it’s easier and more intuitive to install and customize, and there’s even a new lever shape that claims to address some minor issues with the outgoing model without alienating riders who love the current stuff. And yes, there are some surprises, too, both good and bad. Without further ado, let’s get into the shared details.
