Special Guest: Enve Composite’s Jason Schiers

Special Guest:  New Belgium Brewery’s Bryan Simpson

The first podcast of the last Mayan Calendar year is a cracker!  The United States Attorney closes the case, Contador decision & a potential AC fairness fund.  In racing news, Boonen is back.  For those Boonen fans out there, here are couple videos you may enjoy, compliments of Godot.

For those of you who REALLY like Tommeke.

For those Tommeke fans who like that, this may be just the Burger King ad you’ve been waiting for.

And for those who want a little tour fix.

Colnago Rescue Shelter, Highs & Lows, wheels, wheels, wheels, whole greater than the sum of parts?, 1 hour to train & shower, 25’s?, saggy leg warmers, burr & grinder are covered in Listener Feedback.  Finishing things off are a few Best of 2011 calls, with last but certainly not least, St. Albans, Hertfordshire’s own Fun Run Robbie.

Podcast 12/16/2011 & Your ‘Best of 2011′ Cycling Moment

That’s right, you, the listeners’ chance to be part of the podcast yet again.  Beyond the email or attached photo, passed the free style outro message, light years ahead of the random call in, leave a message telling us about your favorite cycling related best moment, ride… whatever of 2011.  They will become part of the next podcast.  The number to call is 513.253.0180.

Powering up down under with some Power Domes

But first, it’s the impromptu Christmas Gift Podcast!  We loosely go over gift ideas to show that someone special how much you care.  Maybe to the well rehearsed and heavily scripted production normally associated with The Two Johns Podcast, rather a loose, freewheel’in list- We even go over a new category, the Bro gift!

Emails, emails and more emails… which category should I ride?  A harrowing melodrama of the podcast’s role in an Aussie relationship, Vittoria CX too fragile for Scottish Roadie?  Wheels or pit bike?  The Airing of Grievances and is aluminum the new carbon?  Dre reforms and now photographs his bike drive side on the camera side, will a trainer ruin my smooth pedaling technique?  Shotgun gives thanks for her expanded lexicon of cycling related words among other comments and are the Johns down with 420?  Answers abound in this, our best podcast of 2011.


Podcast 9/27/2011

Special Guest:  Robin Farina for a pre- World Championship Interview
Is Cavendish a worthy World Champion?  We think so, as we mull over the happenings in Copenhagen this past weekend.  John G digs into the depths of self help books to come to terms with the mostest, muddiest, slippiest cross race he has ever come across.  All this is a prelude to heaping helping of feedback from the likes of  the Aussie Fan, Doctor Big Love, PJ Blue Ribbon with questions  like, why is PBR popular with the cross crowd?  Wheels, wheels, wheels?  more questions of where to go from Ksyriums and the Foam Roleur shares SMART goals with his middle school class and wonders why he can’t close his water bottle as coolly and John G.

These wonderful texts are often accompanied by equally wonderful images.  Below we see Fun Run Robbie’s brother (a 26 min. 10M TT rider), with Fun Run’s Giant Mini Velo that recently took on the Ken Laidlaw Sportive in Hertfordshire.

And below we see the closest finish ever in a recumbent vehicle race.

As with each podcast we award the listener of the week with a t-shirt from our friends at Stomach of Anger.

But first we take a call from the upper midwest, another vuelta another mountains jersey for Moncoutie and Cobo stays in the saddle up the Angliru.  In Local News, one John does two races has one rolled tire, and the other John rolls through one race.  It is all cyclcocross all the time for the near future.

We suspend our rule of no nickname, no read your email for this thoughtful study of Convergence, by Miles.

A cyclist riding on a low traffic road looks up to see car A come around a corner in the distance and is approaching at 60 mph.  At the same time behind the cyclist car B comes around the corner approaching from behind at 60mph.  All three vehicles reach about the same place at the same time and all three vehicles line up and pass at the same point: a convergence occurs.  Why does this happen more than it should?

With over 50,000 miles of professional bicycle touring experience I noticed this convergence happening a lot and set about figuring out what causes it. Below is a much more complete explanation of the phenomenon.  Yes, I have gone out to the road and stood there and watched what is happening.  I have driven into this situation from behind and in front either as a passenger or a driver. Basically drives of cars do not judge the speed of cyclists well and initially assume they are stationary and readjust their estimates over time.  Drivers of cars see a huge pile of paper work if they hit the cyclist and get caught so the cyclist can be a threat to them. The driver approaching from behind tends to slow their speed to pass safely.  The driver approaching from the front has calculated the passing point based on initial speeds not the new slower speed.  Both drivers adjust their speeds just a little to cause the convergence because they never really figure out how fast anyone is going either because they are not use to slower moving vehicles or the speed of the approaching vehicle is constantly changing slightly.

Two cars approach each other on a road and neither car is a threat to the other so they continue driving at the same speed and pass each other where ever they happen to pass.  Mathematically they pass at some point that can be easily worked out with their respective velocities.  If a person is hiding in the weeds next to the road it is statistically unlikely that the two vehicles will pass each other where the person is hiding.

Throw a cyclist into the mix.  Well don’t throw them maybe give them a push with a tail wind.  The first car approaching from the front, Driver A, sees the cyclist as a stationary object in the other lane because the speed of the cyclists is so different than anything they are use to on the road. There is no threat to Driver A unless the cyclist throws themselves across the road into their path which isn’t likely, but happens from time to time with some idiot cyclists.  Driver A continues on towards the cyclist pretty much unaffected by the presence of the cyclist.

The second driver, Driver B, sees the cyclist and at first assumes a stationary object in their lane and slows or gets ready to slow while they figure out what to do.  After a second or two, Driver B recalculate the speed of the cyclist and see it is moving, they will overtake it and will pass it at some point.  To move around the cyclist safely Driver B will have to take up some of the space in the oncoming traffic lane which means timing the pass so the oncoming car is not going to hit them when they move over a little bit.  They do not want all three vehicles to pass at the same point on the road. Does driver B pass before or after the oncoming car?  If both cars are initially going about 60mph and they are 1000 feet apart there is about 5 seconds before the cars pass each other if they do nothing.   One to two seconds of these five seconds has already passed in figuring out the speed of the bike and that passing is inevitable.  Driver B has probably already slowed to give time to figure out the problem they are faced with. Without deliberate intension and through a series of misjudgments about speed of overtaking the cyclist, adjustments in speed are made so all three vehicles arrive at the same point at the same time.  If Driver A is on the ball and sees the convergence about to happen and car B is going to need part of their lane then driver A will also add their speed adjustments to make this Grand Alignment even more possible.  Both drivers want to safely pass the cyclist but continually misjudge true closing speeds to bring themselves all together at the same time.

Pick a point on a long stretch of road and watch how many time two cars pass a given point at the same time.  Not often.  Go stand on the edge of the roadway and watch the cars and see that cars will pass each other at or near the place you are standing much more often.  The difference is the drivers response to something in the road whether it is moving or not.  Ride your  bike down a four lane lower traffic volume road where the cyclist does not ride on the shoulder.  Notice that the cars from behind will most often move over to the other lane and there will not be a car in the oncoming two lanes.  Convergence of three vehicles happens less frequently because no one is messing with their speed.

And of course there is more feedback, but none quite as thorough as Miles.  For that he wins a t-shirt from our friends at Stomach of Anger.

Female Feedback: Part Deux

This supplementary podcast from the female perspective is to fill the gaps left as John and I digressed into imagining Jersey Shore women’s bike racing.  Our last podcast had a parade of questions from women and here to address some of those questions is a woman,  Christy, to our podcast listeners, referred to as Mrs. John K.
