The Only Way You Can Pin Down A World-Class Rider

A few cyclists who are even more dedicated (to what, I don’t know) than I am, or are simply more Retro-grouchy than one of my favorite bloggers, has a pair of wheels with wooden rims.

Once upon a time, such wheels were de rigueur.  After all, wood is light (at least compared to metal), strong and resilient.  All racers used them until Mavic developed alloy rims.  While road riders embraced this new development, track racers used wooden rims until they were banned for competition during the 1950s.

Why were wooden rims banished from the velodrome?

Well, when an metal wheel is crashed, it bends or crumples.  But a wood rim is likely to shatter. That is made all the more likely because on track wheels, the spokes are tuned to a higher tension, and the tires are pumped to higher pressures, than on road bikes.  

The result of an “exlpoding” wooden rim was often a cloud of wooden shards that could shush-kebab riders or spectators.

Decades after the ban on wooden rims, many velodromes have wood surfaces. Nobody anticipated such hazards from them—until now.

Lorenzo Gobbo suffered a previously unheard-of mishap.  Apparently, when he went down, his pedal scraped up a half-meter length of the track that ended up in his back—and pierced  his  lung

He is expected to make a full recovery.  But  you have to wonder: how many other cyclists  have come out of a race looking as if they’d  been attacked by an  by an archer?

In Other Worlds, And Ages

Yesterday, on the 50th anniversary the first moonwalk, I wrote about Dr. Rhett Allain's wonderful article on what it would take to ride a bicycle to the moon.

If I live long enough to see all of that technology develop, and eat my vegetables and drink my milk (I do one of those things now!), I just might make it to the Sea of Tranquility.  

Now that I think about it, I wonder whether I'd want to take such a trip.  After all, if I could go to Paris and bump into someone I hadn't seen in twenty years, who knows who (or what) I might encounter in another world:

How Long Would It Take You To Ride To The Moon?

As a teenager, I followed the journey of John Rakowski, who rode his bicycle around the globe.  In all, it took him three years to pedal through every continent except Antarctica.

Up to that time, one other journey so captured my imagination:  the Apollo 11 flight.  Exactly fifty years ago on this date, Neil Armstrong alighted from the space capsule and became the first human to set foot on the moon.

I must say, though, that the moon landing didn't sustain my interest in the same way Rakowski's trip did, mainly because the trip from Cape Canaveral to the lunar surface took only four days, and a few days later, Armstrong and fellow astronauts Buzz Aldrin (who followed in Armstrong's steps) and Michael Collins returned. 

Moreover, you couldn't escape (even if you wanted to) seeing or hearing about Apollo 11:  literally everything else, from Bewitched to ballgames, was pre-empted for moment-by-moment coverage of the event.  It really took no effort to follow the moon mission.  On the other hand, the only news, it seemed, you could get about Rakowski's trip was his serialized accounts in Bicycling!, which came out every month.

I mention him and the astronauts today because of an interesting Wired article.  Rhett Allain is a physicist who can actually explain his work in terms that folks like me can understand.  Heck, he's even entertaining.  But what makes his article so wonderful is that he takes a seemingly idle question (which, I admit, I have pondered) and answers it in a way that makes the process of scientific research comprehensible and fascinating while showing its complexities.

The question is this:  How long would it take to ride a bicycle to the moon?  The short answer is 267 days, but that assumes that the cyclist weighs 75 kg (165 pounds) and puts out the same amount of energy as a Tour de France cyclist would--for 24 hours a day.  He acknowledges that such a combination of factors is impossible, and that other things come into play, such as what sort of cable or other contraption would serve as the rider's route between worlds and a bicycle capable of being ridden on it.

One thing that's great about Dr. Allain's article is that it reveals just how complicated a task it was to land humans on the moon, and why accomplishing it little more than six years after JFK's proclamation was nothing short of miraculous.
