Apparently you did not read Franks comment, yet quoted it. Odd.
Frank is correct: he stated "Power transmission efficiency drops at least 1% with every chain, belt, or gear mesh between the crank and the wheel(s) right?"
That is precisely correct. If you don't believe that, then you'd have to provide some test results that show otherwise to gain any credibility. Chain manufacturers, who have an incentive to claim high efficiency, do not claim more than 99% efficiency for chains. It is a very rare straight cut gear mesh that is better than 98% efficient. Helical cut are worse, and hypoid gears are worse yet. Toothed belts are advertised as being as much as 98% efficient, but never over 99% efficient.
Math counts. Frank is right.
