gift for Christmas a fancy expensive ultra-light road bike get? Sylvester good focus on good intentions, because of a lot of movement in the new year? And drive less ?.. protect and more Air
Prima Congratulations to all others is the message from the wide world of science:
The UK's Jeremy Groves from the Chesterfield Royal Hospital has a revealing experiment on himself behind. He went for weeks, used 22 km to work by bike at random times with the old steel wheel for 60 €, bought 13.5 kg heavy. Time with a resurrected for 1180 € bicycle light. With carbon frame, aerodynamic, ultra modern, all four kilos lighter than the steel horse. Super Cool indicated. As expected
Jeremy Groves? With the new ultra-light carbon wheels, he would be ten percent faster on the road. At least.
put on a sunny morning of the environmentally friendly commuter because actually a new record and created the hilly 22 km in 43 minutes. Triumph!
But the disappointment after 53 working days: for 28 round trips by Gebrauchtrad required the doctor an average of one hour, 47 minutes and 48 seconds. With the luxury one-third lighter bike, he took an hour, 47 minutes, 21 seconds.
a result which is completely contrary to the beautiful illusion that less wheel weight means more speed. Groves' conclusion:
"A weight loss of the driver promises greater benefit." At lower costs.
