Freewheeling may be a typo. If you were coasting you'd be using zero watts, so you'd have nothing to save.
The pulley does save watts, but I don't know if the 4-6 is correct. The only thing I've heard is that Norman said that. There are no tests on it or anything of that nature.
Where can you find one? Get one made custom like Norman did.
IN triathlete magazine there was an article on Stadler's bike...It said that he had a 14 tooth pulley rather than a standard 11 tooth. It also said that it saved energy (4-6 watts) when "freewheeling" the bike.
First of all, what is freewheeling? I was under the impression that it was coasting, i.e. no pedaling. But if that is true, how on earth does that save energy since you aren't expending energy?
Hopefully someone can explain...I will take 4-6 watts any day of the week by just replacing the pulley...although where I find one of those I have no idea.
