The differences are minuscule and irrelevant for the average cyclist
on his commute.  Small differences in weight and horsepower really
don't come into play until the cyclist is at or near his limit.
Racing, trying to maintain speed uphill, almost late for work, etc.

...don't necessarily get you to B any more quickly than heavy old clunkers.

"A reduction in the weight of the cyclist rather than that of the bicycle
may deliver great benefit at reduced cost".



The results probably depend on all things being equal other than the frame,
for example if the wheels are different widths the results are going to be
skewed, but it's quite interesting. It's quite a commute.



I wouldn't expect it to make any difference in commute times. Those are 
going to be constrained by the route, traffic & such.


Where I would expect to see a difference is in the amount of effort the 
cyclist is required to make to cover the route. If you're going over the 
same route from point A to point B (and back again) every day, it would 
seem to me that a cyclist might expend less energy covering the route on 
a lighter weight bike.


Especially if the rider could combine the lighter bike with becoming a 
lighter cyclist.

depends on whether you're shooting action or landscape I guess =)

The results probably depend on all things being equal other than the frame,
for example if the wheels are different widths the results are going to be
skewed, but it's quite interesting. It's quite a commute.
