    WANTED: Person that has Di2 on a bike in the DMV area

    I've been thinking lately about problems with electronically actuated shifting that uses wireless protocols. If someone out there has a Shimano Di2 setup and lives in the DMV area (MD, NOVA, or DC), I'd appreciate hearing from you so I can record some of the signals and have a look at what the protocol looks like.

    Thanks,
    Kevin

    Maybe I misunderstood?? Di2 is not wireless.

    There IS a Di2 wireless setup but it may just be a prototype outfitted on some pro teams. I'm mostly interested in which frequencies it would be using and the underlying protocols.

    "Thinking about shifting? You already have. The Toyota Prius Project bike combines the forward-thinking innovations of the popular hybrid car, the carbon fiber sculpting of Parlee Cycles, and the computer engieering of the Deeplocal design firm to create a one-of-a-kind technological leap.

    The idea was simple: by using off-the-shelf technology, could they design and build a bike that could be shifted only with the rider's thoughts? They combined a Dura-Ace Di2 drivetrain, a smartphone app and a brainwave-sensing helmet to make it possible. The drivetrain's electronic brain was wired to a wireless transmitter, and once the crew could make it shift with a smartphone, they kenw they were in business. It took a bit of practice with the neuron sensors to activate the derailleurs in just the right way, but it works. What's most amazing is that all of the technology demonstrated here is commercially available."
