Re: Mechanical efficiency of chain drive vs roller drive
The road surfaces in N.Israel are so poor that my chain drive threw its chain three times too often. So I've gone back to friction drive for the moment. Although less power, friction drive is much more sturdy and reliable and tolerant of bumps. Having changed to semi-slicks has also helped considerably. I await to read a proper review of Staton's new axle kit before considering going back to a chain.
