There are cycling apps that allow riders to track distance, speed, calories and much more, but now the UK-based Cambridge Consultants are looking to allow an app to do the shifting for you. In essence this app, when paired with electronic shifters such as Shimano’s Di2 will great an automatic transmission.
The data is reported transmitted by the sensors using low-power Bluetooth Smart and then processed by an algorithm on the handset. This does some quick math, determines the rider’s current pedaling speed to preferred cadence and then instructs the Di2 to shift according.
It can detect those times when wheels slow, such as when a rider a stopping or slowing and shifts to a lower gear. This system is already called ideal for triathletes, but whether it works for roadies is yet to be seen. But could this be automatic for the people?
