Are Expensive Bicycle Wheels Worth the Money? Lets Check the Physics

In this video, you assure a cyclist testing new aerodynamic wheels from Zipp. Swapping your wheels may seem like a small change, but can make a big difference. From his tests, the rider discovers 😛 TAGEND With conventional wheels, he can ride 20 minutes at an average speed of 41. 12 kph with an average power of 379 watts. With the Zipp 808 NSW aero wheels he rides 51 minutes at an average velocity of 41. 13 kph and average power of 344 watts. is the density of air( around 1.0 kg/ m 3 ). ). A is the cross sectional region of the bike plus the rider( how much of the object interacts with the air ). Finally, C is the drag coefficient. This parameter depends upon the shape of the object. If you change the wheels, it is the value of C that should change. 1 2 1
