Probably not, especially if the free speed is to be obtained by adding tiny weights to your spokes. Do let me know if you find otherwise, though, I'd love to put some of these babies on my hed 3.

The guy ought to come over here and defend his idea, then he will learn what thick skin really is! :-)

Personally, I think it would be helpful if he first calculated the overall kinetic energy of the entire bike plus rider system at various speeds and then used that as a basis for judging the effects the relatively tiny changes in rotational inertia those weights represent, and their affect on the entire system inertia.


Also, from the website, the very second sentence from the "rolldown" study begins:


My BS meter was pegged after that ....

Did you notice Frank, on that site there was a section "how it works" . Maybe if you used a "HOW THEY WORK" section on your site people might be more positive towards the Powercrank idea.

Huh? I do my best on my site to explain how they work including videos and many words of attempted explanation. Most people seemingly cannot comprehend what we are talking about until they actually get on a pair as they seem to think PC's are simply the equivalent of single leg drills and since they have clipless pedals, they pedal in circles anyhow. If you have a better way of explaining what PC's are without someone riding them I am all ears, although i suspect that might be hard for you since I don't believe you have ever used them. But, just in case, send me your thoughts.

Probably not "free" speed, but maybe "cheap" speed? For a little extra work carrying the weights in circles up a hill, you'd be able to pick up a greater amount of energy by letting gravity do the work on the way down. It seems to me like it would work..
