Thanks Doug and Charlie for providing this missing ingredient... While I am a big fan of science, I prefer philosophy to guide my riding experience. I ride, therefore I smile... Peace, BB On Dec 15, 1:51 am, charlie wrote: > Right on Doug..I enjoy coffee also. Glad to have contributed >

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. Unless

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 while. Hey, nothing like a good muddle on my Atlantis with no particular place to go nor sche

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 t

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. On Dec 14, 3:09 pm, Steve Palincsar wrote: > On Tue, 2010-12-14 at 14:59 -0800, William wrote: > > I don't get why he repeatedly

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 abou

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 a

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 sport

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 tires
