Given that nearly all the light weight tubing for making bicycles weighs
relatively the same...a tiny variation doesn't seem to make much difference.
The frame itself would have only a very small weight difference from one to
another of these tubes, is my thought. Then realizing what a small portion
of the total weight of the bike is a function of frame weight, it is hard to
see how all this could translate to much difference in the real world.
Perhaps different tubing requires different construction techniques?
Possible, but doesn't seem to be a critical factor.7
When we discuss tire weight, the weight of pedals or rims my attention is
immediately drawn. I feel these things really make a difference in the
actual performance of the bike. The difference in the total weight between
different sets of high quality tubes seems rather inconsequential by
comparison.
I wonder what the frame builders on the list have to say about this? I know
some use a mix of tubing...they must have their reasons...
