　26-inch 29-inch 27.5-inch mountain bike Compare the advantages and disadvantages

First, weight

(1) wheel / tire overall weight (the heavier the wheel is not conducive to climbing and acceleration)

Lighter wheels (wheels + tire) accelerate faster, but also makes the vehicle lighter weight can be, is a combination of a double benefit. Start with 26-inch X g, 27.5 slightly increased 5% by weight, and 29 is a 12% increase on the total weight of the wheels, which allow you to greatly increase the burden when riding, whether it is accelerating or climbing in , the 27.5 is not as we think, so heavy.

Will have the same size with 29 weight 27.5,26 inch models of its class in comparison, you can find significant differences. As expected, the 26-inch version is slightly lighter than the 27.5, and compared to many 29-inch lightweight. Static weight for riding has indeed impact, the more weight the more help you climb faster, more powerful ride.

Static weight difference is one, and the dynamic rotation of the weight of the impact is doubled. As described above on the part of the static weight of 27.5 and 26-inch and 29-inch comparison, is more lighter, but the difference in the dynamic case the effect is huge, deeply affected the performance of the rider when accelerating.

Wheel diameter can be reduced to increase the angle of the wheels in contact with the barrier, which is a positive help, 29-inch wheels in a 6 cm when scrolling through large square obstacle, can be more than 26-inch wheels on the high efficiency 14 % in contrast, 27.5 inch wheels also 9.8% increase. Another comparison is to look at the size of its angle of attack, angle of 27.5 compared with 26 small 4 degrees, 29 degrees is a small 6, the smaller the angle, the more easily roll over obstacles, of course, this part of the best 29-inch, but the performance of 27.5 also very close to 29, but not like 29-inch 27.5 weight so heavy.

Part of this is when the rider urging stampede to accelerate the reaction speed of the car related to the acceleration factors in addition to the static weight of the vehicle about the outside, but also with the weight of the wheels have great relevance, weight distribution away from the axis the farther, the worse the acceleration, the same structure is similar to the static weight compiled from 29-inch 26-inch wheel acceleration is better, because the greater the wheel weight distribution, the more out of the more unfavorable, so we should try to enhance the accelerated reactivity It may reduce the weight of external parts located wheels (rims, head of copper, steel, wheels, inner tubes ...... etc.), as shown below, you can learn only 27.5 wheels slower than the 26-inch by 1.5%, while the 29-inch is significantly slower 3.6%. Comparison of acceleration (the

The larger wheels, relatively speaking, axles will be higher, and higher axle his better nature will come across. 26-inch shaft height of 12.5 inches, the shaft 29 is high is 15 inches, but in 27.5 axle height of 13.8 inches, if compared to 26, will come more than 26 good, but then how than the stable, 29 will be the best, but taking into account the rigidity, stability, under all factors combined, 27.5 will be the best choice.

Lateral steel wheels and wheel sizes is also somewhat related to the larger wheel diameter require longer wire rims and larger diameter, which both result in greater lateral deformation, so that the steel performance is poor. When accelerating and cornering, handling is also less than ideal.

Larger wheel diameter tire can create a larger contact area with the ground, the larger tire contact area can have a better grip, help to improve the efficiency of the acceleration, and braking performance when cornering and tire snake bite chances will be greatly reduced.

Limit the size of the frame design, 29-inch size is often limited by the small wheel diameter is too large, and must ride and handling performance on geometrical be sacrificed compromise can not be shortened from five-way to the rear track and wheelbase so that transmission efficiency is poor, slow steering effort. The first front-end 29-inch car is no longer under pressure, so the small size of the body geometry can not have enough ideal gap. Also look in the larger frame size smaller balance of beauty is not good. The 27.5-inch size is moderate, none of these problems would not have the size of 26-inch size appears larger vehicles ride the ferry situation. 26 The evolution of the 29 inch too big for Asians, 27.5 is the best choice!
