XTR Di2 Electronic Shifting for Mountain bikes!

We knew it! It had to be in the works, Shimano could not leave mountain bike riders out on the most important advancement in bicycle history…

Bikeradar recently posted this article showing prototype XTR Di2  on  a Scott mountain bike. Can’t wait to get it on my mountain bike.

But one is left to ponder… are they really going to release this before they come up with a Dura Ace Crank in BB30? Can you believe this does not yet exist?
