This didn't stop them from claiming some outrageous increase in power output.

I would like to the the full mechanism design, I would like to know how they continuously wind the the spring with out slipping. And to that point I would like to know what kind of spring is used that can withstand the nearly millions of cycles it would be expected to last. It will be interesting to learn more about this.Unknownhttps://www.blogger.com/profile/13033755790922017710noreply@blogger.comtag:blogger.com,1999:blog-13887692.post-54584669604473212622009-10-22T20:02:33.388-04:002009-10-22T20:02:33.388-04:00I'm a doubting Thomas when I see hoopla like t...I'm a doubting Thomas when I see hoopla like this so this post comes as a great lesson!

Which means they are inefficient while producing the same power. I don't know how the e-hub affects all this though, no certainty as you say.Stannoreply@blogger.comtag:blogger.com,1999:blog-13887692.post-89194858204064670122009-10-22T15:45:21.869-04:002009-10-22T15:45:21.869-04:00Insightful post as always.

From the look of the power and HR numbers for these cyclists, it seems to me as if they were already pretty efficient and fit to start off with, even before they put the hub in there. To believe that recreational cyclists maintain their HR at a mere 167 bpm on a 25% grade track is surely way off the charts for me.Smudgenoreply@blogger.comtag:blogger.com,1999:blog-13887692.post-25650916898393649412009-10-22T15:35:36.642-04:002009-10-22T15:35:36.642-04:00Its all about reading between the lines, isn't...Its all about reading between the lines, isn't it?Ron Georgehttps://www.blogger.com/profile/18394865788996482667noreply@blogger.comtag:blogger.com,1999:blog-13887692.post-68585507341814242472009-10-22T15:11:56.818-04:002009-10-22T15:11:56.818-04:00good riddance! you've got the critical eye i o...good riddance! you've got the critical eye i often think im not born with. thanks for a good read.Unknownhttps://www.blogger.com/profile/11626094319696552381noreply@blogger.comtag:blogger.com,1999:blog-13887692.post-25717820872706219582009-10-22T15:06:30.752-04:002009-10-22T15:06:30.752-04:00Ron,
