The Dynamic Synergy is being touted as the world’s first production road bike that comes outfitted with an internal gear hub. No doubt, IGHs are still not as efficient as derailleur systems, and they come with a weight penalty as well, but this is an indication that they’re getting lighter and more efficient. I suspect we’ll see more of this in the future as IGH technology continues to evolve.
From the American Heart Association:
PALM HARBOR, Fla., March 13, 2009 —People who have had a heart attack are likely to report having been in traffic shortly before their symptoms began, researchers reported at the American Heart Association’s 49th Annual Conference on Cardiovascular Disease Epidemiology and Prevention.
In a German study of patients who had a heart attack, researchers found the patients to be more than three times as likely to have been in traffic within an hour of the onset of their heart attack. The researchers also observed small but statistically significant increases in the chance that a heart attack occurred within six hours after exposure to traffic.
Driving a car was the most common source of traffic exposure, but taking public transportation or riding a bicycle were other forms of exposure to traffic. Overall, time spent in any mode of transportation in traffic was associated with a 3.2 times higher risk than time spent away from this trigger. Females, elderly males, patients who were unemployed, and those with a history of angina were affected the most by traffic.
The entry period for the EcoVelo Photo Contest is officially closed. If my tally is correct, we ended up with 411 photos! We’ll start the judging process this week and if all goes as planned we’ll have the winners for you within the next 10-14 days.
I had to bring back the Shop Quail as it seemed there were these unbelievers when it first appeared on your old blog. Then a couple of my favorite customer trikes that struck me as being very cool. The S&S coupled GS GLO and the super matte black finish made it look very stealth. The finish was so course that decals were supplied, but not applied. Would ruin the look anyway. The Catrike 700 with customer upgraded components such as the Dura-Ace 9spd STI Brifters that took a test ride to become a believer. —Rick
