Interbike 2011: Close look at Shimano Ultegra Di2, cyclocross parts

We got our first close-up and in-person look at Shimano’s new Ultegra Di2 electronic shifting group today. There wasn’t a bike available for test riding, but it’s clear the new system is even cleaner and easier to integrate with the frame than the Dura-Ace version. Where does this leave Dura-Ace Di2? I would expect a major update in the next year.


We also saw the new front derailleur and chainrings specialy developed for cyclocross racing, as well as new cantilever brakes. The deraileur is a top-pull design, which eliminates the need for a pulley when routing the cables along the top tube. The chainrings are now available in more race-friendly sizes. 

The new cantilever brakes will work with any road shift/brake lever, but are optimized for Shimano’s latest series of shifters, which have a slightly different cable pull.
