I have spent some time looking over the pictures of their CVT on their
website repeatedly, and I have some difficulty in understanding just how the diameter of the pulleys is changed by the weights. From looking at the pictures, I see that the weights fold out when the shaft is spinning faster, but I see that the pulleys remain at the same diameter. Is this a friction based CVT, because I see that the man's hand in the background is holding onto the shaft tighter in one of the pictures than in the other.
Can someone on team 494 possibly give more information?
