Very cool Andy - I like. :)

Does anyone know if the big S plan to make the Di2 system wireless? Was Wiggins' version which went wrong an experimental wireless version?

Presumably you would just need to put a battery in each mech and a watch battery in the shifters? Or am I ten years ahead of myself? :)


Yes, you're years ahead, first they'll link the system to the GPS to locate the position and the gradient, live weather info via location and 4G networking, heartrate via a monitor and cadence via frame sensors.

Once this is tested it'll go wireless.

Gear selection will be automatically chosen based on gradient/weather/wind and sensors to select the best gear to propel the bicycle the fastest given leg power output.

Well, since there are XT Dynamo hubs and Ultegra Dynamo hubs it looks like even Shimano accept batteries are a weak point in it's quest for an electronic shifting world....
