What kind of Cycling enthusiasts are the carbon fiber bike rims ?-Ekay Original article
2016-04-26
Level 1 bicycle
Cycling around can be divided into three levels: 1 commercial grade (vegetable vehicles); 2-entertainment-level; Grade 3 race. Entertainment stage and race level bike can also be referred to as "motion class." In summary it can be said with vegetables and general commuter car is compared to two things.
Civilian-level price of between about 100-2000, entertainment level price between about 3000-20000, tournament level between 20000-100000 (both RMB). There will be different types of vehicles are some differences, relatively low fancy bike (small wheel, BMX, dead fly) the price, the higher the price of road, downhill bike.
Getting cycling enthusiasts recommend to buy more than 3,000 cars, which is the entry-level entertainment. This level of the car and the general nature of a vegetable trucks there will be differences in configuration and performance to meet the needs of long-distance cycling movement and security aspects. Although many people can ride big twenty-eight Princess car on Tibet, but between ride and ride feel, performance, pleasure is different. If economic conditions permit, the vehicle of 3,000 yuan is not recommended to buy. Even if you buy a $ 2000 used car, do not buy a new car about 1,000 yuan.
Advantage 2 level sports bike
And civilian vehicles compared to the performance benefits of sport bike class is mainly reflected in the following aspects:
1 high-strength, high impact resistance. Usually your car from the 5th floor stairs Tinker Leverage ride down triaxial will destroy, but an exercise bike can be done safe.
2 durable and strong, even after a long ride performance of the structure of the vehicle will not be significantly damaged. Common cycling 1000 km in the rear axle after the general need depth maintenance, brakes also need to readjust care. But sport bike without. Even after riding thousands of kilometers, the average car may have thrown away, but the movement still has a good level of performance bike.
3 light weight, aluminum frame internal exercise bikes (and possibly other materials) wall thickness is different, the purpose is to reduce the weight. Other configurations will also try to ensure that the strength in the premise of reducing the weight by grinding, drilling and other methods. These steps will increase costs, but also improve the riding experience. A lot of people riding the car lovers breath came through the fifth floor expressed admiration, but for most people to do the same to lift up.
4 excellent performance, the most obvious is good braking performance, stable and easy. Gently pinch wheel lock can be done. Second gear transmission system cut accurate, smooth operation. Finally, because light weight and other reasons, after the car ride up and you will find its acceleration, top speed, there will be (except for fancy cars, trucks and other vehicles downhill, because they were not doing that) superior performance.
3 exercise bike configuration
① frame and axles: In the specific configuration, the sport bike uses superior performance level of aluminum, titanium, scandium alloy, carbon fiber and other materials. These materials generally have a lighter weight and structural strength. In order to facilitate pumping pipe processing technology to achieve weight and balance, exercise bicycle frame is generally more bulky, but part of the structure of the wall thickness is not necessarily higher than the average of the bicycle frame, the frame may be part of an exercise bike in the transverse strength There were weaknesses. Ordinary bicycle triaxial typically use the bowl axis and sport bike uses a closed Peilin axis, this axis in addition to the advantage in strength, the biggest advantage is maintenance-free, not like an ordinary bowl axis as a year in March wash change.
② transmission system: now SIS transmission system in the civilian car also began to spread, but the movement of the bicycle transmission shifting will be more easily and accurately, because of the higher precision, adjustment process requirements. In addition to folding, and other fancy vehicles, general-level sports bike gear position to be more than an ordinary bicycle, riding to meet the needs of complex environments.
③ Brake System: Civilian ships using V brake or hoist brake, drum brake. Level sports bike disc brakes or the general use of oil disc brakes. V brake although there are high-end products, but because of some inherent defect, people have now used less and less. Oil disc brakes or disc brakes maximum use of experience stable performance, once installed in almost not go to hell for months and years, only occasionally can adjust the look. Ordinary General V brake brake pads will be about one hundred kilometers significant wear, you need to re-adjust. Even the best brake pads using thousands of kilometers even improvise ride can not do, and must be replaced. Many people think that complicated calibration disc (brake oil was a little more difficult), but if you learn to adjust the way you will find more accurate and reliable calibration disc brakes, unlike the V brake had a lot of uncertainty, disc brakes overall maintenance costs are much lower than V brake.
④ riding posture: Sport bike stage one of the greatest features is all too familiar: that is, you gotta ride position. Bicycle handlebar height movement generally lower grade, the high seat. The aim is to balance the body weight, so the weight of the body evenly spread over the arm and buttocks, in order to meet the requirements of long-distance riding comfort. Otherwise, the car with the princess posture long distances, anybody's ass will not stand. But if you share the weight on the arm, buttocks burden will be greatly reduced, overall comfort, there will be a qualitative improvement. Course, before anyone to get used to it, then you can appreciate the habit of riding need for such a gesture.
⑤ seat: So there will be no sports bike seat electric bread princess car or bicycle. Bread seat surface looks very comfortable, but for long-distance + Jue Ding riding position, it is worth mentioning: the buttocks because pressure is not great, seat cushion depth bread in fact, most do not have access. Too soft seat make the seat tightly clad rider's crotch, which impede blood circulation and heat dissipation. More pit father is part of the thigh and the seat will be repeated friction kneading, leg waste energy, hindering the normal force. So the use of small thin seat on an exercise bike but will enhance the riding experience.
⑥ Fork: movement class mountain bike suspension fork are normally used. The high-end vehicles typically use gas fork. High-end fork is characterized by light weight, responsive, and part of the fork will have long stroke (depression depth) to meet the needs of off-road riding. Most fork function will be locked after the lock can be adapted to the flat road riding. So only use fixed road bike fork (hard fork), mountain biking soft fork. Downhill bicycle fork using a long stroke. Touring bicycles using high-sensitivity short-stroke fork (fork as hard wrist strain will increase, so the car is not suitable for long distances by road). Civilian vehicle suspension fork is a decorated general, sensitivity generally low, you need to have little reaction to severe turbulence (too hard). Or too soft, tiny jolt will hit bottom (damage fork life). And this type of car front fork oil is also very poor quality, the winter may freeze. So many civilian car in the summer it feels okay, but in the winter it becomes a hard cross.
⑦ fender and rack: Sports bicycle fender rarely used (except wagon), because in the long-distance, high-speed riding environment, mud fenders for dust blocking ability is not outstanding, but also bring additional weight and wind resistance, stability in the presence of additional risk. So level sport bike mudguards are generally not even shelves with not much. Of course, except the station wagon, the wagon has most of the shelves, or even three or more racks and fenders.
