I'm interested in seeing the outcome, not because I'm a serious cyclist (MTB) by any means (not even in my wildest dreams ), more so from the stand point that this was done on compound bows oh so many years ago and a lot has changed since it started. Now nearly all compound bows have them from the factory.
It will be interesting to see, what the development of this will bring when someone hits the sweet spot with these and they get accepted. I can see that long term developed properly, that rider could greatly benefit from increased power with reduced effort under almost all conditions. I suspect though that all of the gears on the crank must be changed to maximize the performance and shift patterns. Ring shape is going to be determined by power application and feel. Equal full power throughout stroke or maximize peak at maximum stroke. What could make this more interesting is being able to adjust the ring for application point on the fly (ie letting the ring be moved).
Be interested in what the serious riders feel development will be like.
