The DigitalJer Challenge
Feedback is encouraged at cycling cosmonaut. It seems that one devoted reader wishes to challenge the expertise and intellect of Mr. Barry Hamlin. DigitalJer proposes: Terminal velocity can be solved for in the cycling equation above by setting power at 0. If one assumes the rolling resistance term is also 0, and that there is no wind blowing (v = s), then the equation becomes: kaAs3 = -giMs or s = (-giM/kaA)1/2 Thus, the terminal velocity is roughly proportional to the square root of the ratio of M/A. Scaling reveals that larger cyclists have a greater ratio of mass to frontal area. They therefore descend hills faster as a consequence of purely physical, not physiological, laws. Since the larger cyclist has a greater mass, gravity acts on him or her with a greater force than it does on a smaller cyclist. We thank DigitalJer for his audacity by questioning Barry Hamlin's scientific logic. However, Barry Hamlin is known as "Pope Barry of Cycling" and as such is infallible. DigitalJer should now expect the Spanish Inquisition.

Lampo Pre-TdF preparations
Lampo Bianco has hit upon a radical but extremely effective method to get down to racing weight. With the Tour de France looming, Lampo found himself a few tens of kilos over his preferred racing weight. Somehow, he picked up a particularly virulent 31.4 hour virus. Whether it was from a toilet seat or air borne, experts are baffled by the puzzle of its origin. The virus's effectiveness cannot be denied. In the space of 24 hours, Lampo Bianco purged all excess liquids, dropping his weight precipitously and giving a workout to the sewage system of his local municipality. Bravo and chapeau LB! You are an inspiration to us all.

The Pros and Cons of Weight Loss
The struggle against weight loss is universal to cyclists the world over. In order to ride efficiently and effectively, one should have minimal body fat and maintain a diminutive stature, preferably less than 1.57 meters. Speaking from experience as a formidable bike rider at 1.95 meters, weight definitely has advantages. Plunging down any hillock, tolt, hilligen, sinuous mountain track, coulee, downward facing switchback, or sloping driveway allows gravity to work its magic on the bigger rider. Often I find myself reaching subsonic speeds causing facial disfigurement.

You know it's windy when...
You know it is windy when: 1. Pedaling required down a 6% grade just to maintain forward momentum. 2. Skin tight spandex flaps in the wind. 3. Being passed by a loser on a recumbent. 4. Strange white crustiness develops around the mouth. 5. Sun burn superseded by wind burn on face. 6. Ambient temperature is plus 20 but feels like plus 5 degrees C. 7. You plead with the devil to instantly become 1 foot shorter and 100 lbs lighter. 8. You ride in echelon formation (shown below)

Throwing down the gauntlet
Yesterday, Johan threw down a gauntlet and demanded that Team Vitesse riders get off the couch and train since the Giro starts on Saturday. Immediately excuses began to fly. Dr. K2 pleaded that he had to learn his children's names again and could not go. Lampo Bianco assured Johan that he has been training regularly but there is no way to confirm that. h2o suited up after his green eggs and ham dinner, pumped up the tyres and grabbed some gloves because it seemed cold and threatening. Realizing that the climatic conditions compromised his hand warmth, h2o attempted to put on his gloves. The 2 right handed black neoprene gloves did the trick and kept his hands warm. Unfortunately he could not bend his left hand against the neoprene form fit. h2o claims that the glove discomfort reduced his average speed by at least 5 kmph.
