This time it’s about a new electronic gear shifting system from Shimano, called the Di2: http://www.wired.com/gadgets/miscellaneous/news/2008/07/shimano?currentPage=1
It’s rather expensive now, but that’s what people thought about the first pocket calculators as well. And look where we are now. Looking forward to 2014 when bikes will come standard with servo gear shift, anti-lock breaks and traction control.
The problem is the battery, which just is not lasting enough, and after a few hours will leave you unable to shift gears. I wonder why they won’t go the route of a dynamo, not the classic one that rubs against the tire of the front wheel, that would be simply unacceptable in a racing bike, but something using the force of the wheels spinning or something. They should figure this out, they are the scientists.
