or D) Dont agree with your comments and opinions. Tourers schlepping a 30lb bike plus 40lbs of stuff up a mountain and/or all day 100km ride are expending a heck of a lot of energy just like a "racer", so while you are convinced there isnt an efficiency gain I cannot change your view, but I will however take any help in my schlepping, especially up hills.

and E) as we don't have to all wear Chairman Mao uniforms, folks will make up their own minds, going from all opinions if they dont have a chance to try some before on their own.

cheers and good riding no matter what your pedals.
