For fans of electronic shifting, or at least the curious, we’ll have a full ride report/review on the new Shimano Ultegra Di2 electronic group in a little more than a week.

So, assuming there are no production delays, you should start seeing this stuff on bikes in your local shop later this year! More pics after the break…
