29er: new mountain bike descent, with the conventional bicycle 26 inch wheel diameter different, with a 29-inch design, brings many exciting new features! Some people may think that these "big wheels" like a clown riding a car, but in fact most of them, and no in-depth study will have this idea.
Despite the small number of people to resist, but the 29er mountain bike are becoming mainstream. See every year more and more appears on the 29er bike shop and Hill. In 2010, the United States and British mainstream car brand 29er store almost all sold out! And many world-class riders is using these "big wheels" and win a game. This is the time to draw our attention.
Size determinism 29er 26er Let us return to 1986, Dr. Alex Moulton, because he invented the cozy little bike wheels are well known. His car was a 20-inch wheels and all-terrain bike. Unfortunately, Moulton ATB (All-Terrain Bike) has an essential defect. When you're riding now those 26-inch car can ignore small potholes, they are authentic reflected on his car. Although the vast majority of mountain biking that are age structure of the whole Ying Jia, his shock ATB with amazing comfort and handling, the car or the car 20-inch inevitably become obsolete.
If you've ever been riding on the standard Hill BMX, I never forget that painful experience. Small wheel diameter, and small wheelbase, is not conducive to riding over rough terrain. Imagine, when other conditions are the same, big wheels touch the ground arc to make it easier to pass uneven ground. However, we can assume that these big wheels faster terrain it? Not always the case, because there will be more complex cases need to be considered.
Take for shock. In theory, all forms of shock, including the 29er, and seem to be able to make the terrain becomes flatter. But the shock is installed on a 29-inch mountain bike is much more complicated than in the 26-inch board. Because the bigger wheels, shock absorbers can be placed space becomes smaller, it is necessary to redesign the frame. And
bigger wheel frame geometry needs to be redesigned to let the car in the best condition.
Larger wheels and tires while the car will become more important, which is not conducive to enhance the speed. Although the 29-inch wheels protruding through the diamond when it would be easier, but the performance in other types of potholes is not entirely true. Small wheels momentum is small, easy to accelerate, but the big wheels to better maintain the rotational inertia. So, even if we find the optimal frame geometry design before, we should not arbitrarily say because the big wheels roll more smoothly so they are better.
How much should you use a wheel? Now the mountain bike market is still ruled by 26-inch wheels, it is very easy to understand. Since the average size of drivers, coupled with a crude tire has been able to meet the requirements of mountain biking. And 26-inch wheels effortlessly mounted on a common frame structure size regardless of stained mud after leaving the problem of insufficient space.
