Posted - 03/03/2017 : 13:26:31 Hi,
this is my first post. I'm interested in HPV:s but not active.
I read the rules with regard to some imaginary projects in my head.
Rule 3.1.1 states that no control devices may be powered by non-human power sources. This makes me wonder what a control device is. Are the Shimano Di2 derailleurs control devices?
If anyone have thought about this or know the interpretation of this rule I would be very grateful if you would let me know.

It is also my understanding that the rules only prohibit non-human powered sources that contribute or might be construed to contribute to the forward momentum of the vehicle.
