The article leaves many unanswered questions. How much did he carry
on his commute, how often did he need to stop, were there hills to
climb, did he monitor his efforts by heart rate to screen out
unintentional bias, was he trying to ride to the same perceived effort
or the same speed? What
Do you think some unintentional bias was causing him to ride harder on
the steel bike in order to keep the same time? If so, it was
remarkably consistent over the course of 56 rides and nearly 1500
miles.
Commuting with stop signs would give the lighter bike an even bigger
advantage than in
In this case it's more of a riding style than the bike. As much as we
would like to ignore or minimize the speed difference weight and
equipment makes, it does exist.
Even if in most cases it's areodynamics.
1 2 or 3 mph average speed is nothing right? It could still add up to
15 percent if you

Thanks for the link.
While the author does not describe the hubs on either bike, he does
point out the plastic bike had lighter and obviously more expensive
wheels than the steel (obviously as the entire steel bike cost him 50
pounds).
Appears there are modest hills on his commute. Not sure
It seems like he did the best he could to be unbiased. I cannot imagine doing
this starting out with a particular result in mind.
I think the results are valid.

That's true. In the news today, stem cell transplant cured HIV on
the berlin subject. I think they threw in that the berlin subject
should also lose some weight.

Actually a cyclist should gain weight in the form of muscle in his
legs (horsepower) and lose body fat overall thereby increasing his
cardiovascular efficiency. Aerodynamics influence speed more than any
factor including power output of the cyclist but given a similar
riding position between the
I especially enjoyed Grant's notion that if cycling is fun, why would
one want to rush it? ...muddle on... has been a successful riding
technique I've enjoyed (thanks for giving it a name!) for quite a

Right on Doug..I enjoy coffee also. Glad to have contributed
to the vernacular of cycling lingo. Confused as the word muddle is,
that is exactly what we do when we ride with the idea that we must go
ever faster from point A to point B on our bicycles or we just aren't
doing it right.
