Hi all, I would think that overall weight is important, weight matter
wether going uphill or along the flat, the more weight and wind
resistance the more energy required to drive that bike, sure rolling
resistance of the tyres and friction of the drivetrain also come into
that equasion as well, sorry about the spelling.
Wheel weight having the centrifical/flywheel effect does affect handling
as well as engergy required to drive, one could babble on for hours all
about this I am sure, and there would be so many different ideas as well,
so I guess we will be in for some good reading over the next few
days.........regards wayne davidson Invers NZ........
