I played with it a bit at Interbike this year. It was watched by a Shimano tech pretty closely. I was able to pedal it and shift through a few gears as it hung from a repair stand. I would say that making the derailleur shift is similar to setting a microwave. If you want popcorn you push the popcorn button. If you want to down shift, you push the down shift button. Current versions would be similar to a crosswalk button. You just keep having to push it till the crosswalk sign lights up. Ok, maybe the older stuff doesn't work like that but the Shimano Di2 does shift quickly and it even adjusts quickly too. The biggest reason for this is a simple: input equals output. Current cable systems have lots of opportunity for error. Anytime you have two parts moving over another there will be friction. Friction increases as you add the elements of dirt and rust. Or maybe it's just a case of your housing ends not getting cut cleanly. With Shimano's Di2 you eliminate that because there are no cables. Zip over to
Bike Radar to learn a little bit more info.
So the reason for this post is, if there is anyone looking to pick up the new Shimano Di2 please let us know. We have the option of possibly getting a set or two. 605-275-2453. Ask for Kyle.
