Indeed, I recall that my PX-10 was 21#, just as Peter Kohler stated. My
Masi 3V Volumetrica is 23#. Anyone riding the two would immediately notice
that the Modern Masi is faster and more responsive to pedal pressure. I'm
sure there will be those who would not agree with me, but please, if you are
going to be vehement about it don't do so without having owned and ridden
both bikes...folks speaking strictly from theory would do well to be gentle.
Now why do you suppose that weight should not be the determining
factor...gearing? Stay stiffness? It sure isn't my 30 years older now
legs! I have long pondered just what makes one bike faster than another
(other than the rider) and I'll be darned if I can say for sure. I'll bet
some of the frame builders or racers can illuminate the issue??
