Every July millions flock to the Champs-Élysées in Paris—and hundreds of thousands extra to their televisions and computers—to witness the dramatic end of the grueling 3 weeks of the journey de France. there isn't any greater degree of the global love of the bicycle. yet of the 1.2 billion cyclists traversing the world’s roadways and trails, few people take some time to think about the technological know-how in the back of the game. the easy means of getting approximately on wheels brings us in contact with a wealth of attention-grabbing technological know-how, and the following journalist Max Glaskin investigates the clinical wonders that continue cyclists of their saddles.


Cycling Science excursions readers via a wide selection of issues, from tire rolling resistance and the adaptation among yield energy and supreme energy, to the significance of aerodynamics and the influence that shaved legs have on velocity. every one bankruptcy explores a distinct subject—fundamentals, energy and balance, fabrics, strength, aerodynamics, and the human factor—and is geared up round a chain of questions: what's the perfect body form? what's the greatest resource of drag? What retains a bicycle from falling over? How a lot energy can a bike owner produce? Which muscle mass does biking use? every one query is tested because of explanatory diagrams and illustrations, and the ebook can be utilized to go looking for specific themes, or learn via for a entire evaluate of ways laptop and rider paintings together.


Athletes have a lot to achieve from figuring out the technology in their activities, and Cycling technology will be a must-read for cyclists of all stripes—professionals, leisure riders, and somebody trying to improve their delight in cycling.

79 How are solid metals joined? What sticks my frame together? Solid/liquid cycles: welding Welding rod melts into the junction of the tubes Adjacent tube ends melt An arc (spark) from welding rod to tube junction Surface tension Face Nearly every metal frame is assembled by either welding or brazing the tubes together, and both methods involve turning solid metal into liquid and back again. The joints must be at least as strong as the tubes, and the frame builder achieves this by harnessing the complex chemistry of hot metal.

Heart rate was also slower, by 20 to 50 beats per minute. 12 In other words, despite the added weight, it was significantly easier to ride a fully suspended bike. 58 Strength and Stability a Smoothing out the bumps On the rough stuff, suspension wins out. The blue line shows the vertical forces on the front tire of a mountain bike riding over a single bump. The red line shows the same bike but with front suspension added. 15 (This is all fine for rough terrain, but it’s a very different situation on smooth asphalt.

Trial and error have taught bicycle mechanics which metal is best for each part of a bike. Quantum mechanics explains why. The bonds between metal atoms pull them into a repeating pattern (much like a collection of ball bearings settles together). Such a long-range pattern forms a crystalline structure. This tight packing makes the metal resilient, because it allows atoms to slide over each other, just as it’s easier to ride over closely packed cobblestones than ones with big gaps. The cobblestones on the Paris–Roubaix race are not just a test for riders; the infamous pavé also hammers the very atoms of their bikes.
