It?s big excitement here in Tech land today ? Madison has sent us the Shimano Dura-Ace electronic Di2 groupset to play with for the weekend.

The Di2 groupset is the only one in the country and has been sent directly from Japan for the Cycle show this coming week, (10-12 October) so is built onto a bike ready to roll. As they need it back on Tuesday they?re only allowing us the weekend to ride it but I?m sure that?s enough time to do some damage!

Dan and Mike have literally just spent the last hour playing with it and very impressed they are too. With no instructions it was a bit of a guessing game as to how it worked and they managed to break the shifting for a while after fitting a Campagnolo wheel and adjusting everything to make that work ? all credit the Campagnolo cassette did work, even if not perfectly, and they even managed to get it set up for Shimano once again.

Fitted to a 55cm bike Dan is going to have the privilege of using it for the weekend and telling all in next week’s magazine.
