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.
