You can choose the giant's things: XTC3 shelf (slightly lower price), ATX7 shelf (price 6XX), or ATX8 shelf (slightly higher price). These shelves are very representative, and the budget within 3000 can be configured.
Optional Moso: Moso shelves are highly recommended (price 6XX). However, please note that shelf 07 is selected, and shelf 06 cannot be selected. The difference between them is that the lower tube of 06 is reinforced and the lower tube of 07 is integrated. I'm sure the old bird will tell you this. The weight is very light and strong, and no one dares to say that Moso's shelves or giant's shelves in 6XX shelves are better. You are sure to drown.
For comrades with great power, such as 0. 1, the first consideration for such comrades is firmness. Merida shelves are recommended. There are many choices, but the price will be higher. You can choose Miami and pro (price 7XX——9XX). These two things are very good, 9XX can buy shelves known as the European version. That thing is better than other 7XX products in workmanship and local pipeline design.
To choose what is your own career, all the above choices are positive solutions. Just choose what you like. Someone may choose $ TERM (price 16xx- 18xx). That's a personal hobby, but the budget will definitely exceed it, and you still have to choose a poor one. At the same time, you can also recommend another XTC (price 13XX) shelf.
Ha ha. But you'd better honestly choose the shelf of 6XX. These shelves mentioned above are all alloy aluminum shelves. Other shelves are not recommended.
I said the shelf is very simple, because beginners know the above is enough. For example, ATX7 is more suitable for long-distance use than MOSSO. Moso is divided into upper and lower lines. These are deeper differences. Birds can check themselves more. Don't want to bother, just pick.
Forward fork: It is recommended to buy 3XX-4XX forks. This question is relatively simple. There are many choices of fork brands, and the old bird will tell you that there must be a difference between 3XX and 1XXX forks. But this difference is not very big. Buy a better quality spring fork and pay attention to wipe the dust. A little more oil will make it more and more useful. There is no choice of brand here. Just find an old bird to take you when you match. Prevent the suspicion of advertising. Fork is a very complicated hunger problem, which has a lot to do with use. Imagine that there is a difference between walking flat every day and flying 1 meter high every day. So don't give personal examples. Welcome everyone to clap for what I wrote above. There are no bones in the eggs, but who can guarantee that the hatched chickens have no bones?
Brake system: Disc brake can be selected, and V brake is recommended. Disc brakes are cool in appearance and more expensive than other brakes, so I think disc brakes must be very good, so I don't buy non-disc brakes. The final result of this blind consumption is a great waste of money and energy.
Disc brake: generally, the price is higher. Cheap disc brake shaft, 2XX can be bought. Generally, the price can be guaranteed to be around 5XX (not connected to the shaft). The weight is still very heavy. Personally, I don't like disc brakes. Adjusting the disc brake is a technical job, which is not easy to adjust. The only advantage is that the shape is cool and the weather conditions are better, because the V brake may be affected by rain, and its performance will be reduced, and the disc brake is not easily affected by the weather. It is said that a novice bought an 800 disc brake and only rode for a few kilometers. After a very urgent brake, all the brake discs were deformed and the car could not move forward. Therefore, warn friends who go to the disc brake that they must buy a better disc brake. That's the CD of your life.
V-brake: it is not that V-brake is better than disc brake, but that V-brake is cheap, light in weight, low in use cost, convenient to adjust and good in performance. Compared with disc brake, V-type brake is made of rubber, which is more flexible, easier to control and relatively difficult to lock. Buying 100+ V brakes is similar to using 500 disc brakes. Those who especially like disc brakes are not allowed to pat bricks!
I suggest you buy a V brake at a price of 100. Cheap and easy to use, even if it is changed in the future, it will not hurt. There are AVID (5 series recommended, of course, the price may be more expensive) and Japanese ones to choose from. See if you like it. The choice of V brake and disc brake has great influence on the configuration budget of the whole vehicle. So put it in the front. For those who want to save rice, it is right to choose V brake. The final result of choosing V brake is that it can have good use effect and cheap price.
Welcome everyone to clap for what I wrote above. There are no bones in the eggs, but who can guarantee that the hatched chickens have no bones?
Variable speed system: this is a problem that attracts people's attention. But there is only one fact. How do novices choose the transmission system? Let's take a look at the following introduction about the variable speed system:
At present, there are only two brands that can choose variable speed variable system, Shimano and sram, and the others are not without them, but they are rarely seen in China. Because Shimano invented sis technology, it mainly refers to its unique design flywheel. If you look closely at Shimano's flywheel, you will find that every tooth in his tooth plate has a different shape, some are high or low, some are like a piece falling off, and some are so thin that it seems to be only half a piece. It is this unique shape that enables the chain to move smoothly from one tooth to another under full load during the speed change process. It was also because of Shimano's patent that he suddenly took the position of the boss. It was not until Shimano began to agree to sell flywheel separately that other manufacturers were able to break through this technical barrier. Usually, when loading a car, a big choice is to fly back at a few speeds. Flywheel, rear derailleur and gear lever are unified and must be matched when purchasing. At present, flying after 9-speed has become the mainstream. Delaur and most importantly, use a 9-speed system. What are the advantages of more speed? Just like a car gear. The maximum output power can be guaranteed at different speeds. Fine transmission ratio changes can give full play to your physical strength and ride at the most appropriate frequency and speed at any time. On the road car, even the 30-speed shift of 3 * 10 * * * has been used. Another common system is 8-speed. Many old parts and entry-level ones fly at 8 speed. The biggest advantage of 8-speed is economy. For mountain bikes, fine speed change is not a very important requirement, because the terrain of mountain bikes changes greatly, and a wider speed change range is more important. Generally, it can reach the range of 1 1 tooth to 30 teeth at 8 speeds.
In the matching of transmission system, the matching of parts of the same transmission series is of course no problem, but the matching of different series of vehicles should be compatible. Generally speaking, the chain of the 8-speed system cannot be used in the 9-speed system, and a derailleur may be used, which is best avoided because the teeth and chain of the 9-speed system are ultra-thin. The compatibility between 7-speed and 8-speed is much better. The range of parts to choose from is also much larger.
Detailed differences between Shimano-class kits
Up to now (February 2007), the models of SHIMANO's various grade kits are
Mountain: competition; ; Altus; acera(M340)； A livio (M 410); Deore(M530 for M530 disc brake); Deore LX(M580 for M580 disc brake); Deore XT(M760 for M760 disc brake); xtr(M975)； For M970 disc brake); And HONE(M600；; ; Saints (M800)
Highway kits: 2200, SORA(3300), TIAGRA(4500), 105(5600), Ultegra(6600), DURA-ACE(7800).
Detailed comparison only discusses these latest models, starting with the details of each part, and after reading it, you will understand where the differences of each grade are.
Sa: TOURNEY is not strictly a complete set of packages. Its positioning is that the entry-level movement supports 6/7-speed Acer and ALTUS. There is no obvious difference in prices, which can be simply understood as the same level. Acer is mainly equipped with 8-speed, while Acer and ALTUS are mainly equipped with 7-speed (in fact, they are both compatible with 7-speed and 8-speed). Compared with TOURNEY, it has increased 8-speed support. Acer's back dial-up connection pins include
ALIVIO is also an 8-speed kit, and now M4 10 is already a complete kit. In addition to the characteristics of Acer, it is better than Acer.
1. The rear dial adopts wide connection, and the two connecting feet are coated with fluorine.
2. The front dial adopts wide connection.
3. The form of variable speed handle has changed from EZ FIRE PLUS of Acera and ALTUS to a more advanced RAPIDFIRE PLUS.
4. Cranks began to be connected with eight-bar splines.
5. This grade of flower drum began to be quickly disassembled with aluminum.
6. Matching HG50 flywheel with chrome plating
Deore starts from Deore and all adopt MEGA 9 system, all of which are 9-speed. In addition to the characteristics of ALIVIO, Deore is superior to ALIVIO in that
1. The rear steering wheel is made of stainless steel screws and chrome steel bearings, and the tab pivot is sealed with O-ring, with low standard design.
2. The hub of the hub of the hub is super-precision polished, and the axle bowl is polished by roller and sealed by double labyrinth.
3.9-speed HG flywheel HG50-9 is made of nickel-plated steel.
4. It's all four. M530 and M535 have dual control handles.
5. The front connecting steel is galvanized and the chain cover is chrome plated.
6. The crank adopts hollow technology, the first generation technology crank, eight-bar octagonal spline connection and stainless steel screws. The big and middle teeth are made of aluminum, the small teeth are made of steel and the crank arm is made of aluminum.
7.HG53 chain is made of taupe steel.
In addition to the characteristics of Deore, Deore LX is superior to Deore in that
1. The material of the back dial is harder and thinner, and electrostatic coloring is adopted accordingly.
2. The hub bowl is polished by non-roller.
3.M580 flywheel is made of pearlescent steel.
4.HG73 chain is made of gray/gray steel.
5. The crank adopts the integrated central shaft and hollow second generation technology of HOLLOW TECH II, and the crank arm adopts forged aluminum.
In addition to the characteristics of Deore LX, Deore XT is superior to Deore LX in that
1. The rear tensioner adopts sealed bearing, the pull ring pivot adopts double O-rings, and the guide plate pivot also adopts O-rings. All four connecting pins are coated with fluorine, and the inner and outer guide plates are made of aluminum.
2. The crank arm is made of forged aluminum with high hardness, and the big tooth piece is cut with 7075 aluminum. The middle tooth piece and the small tooth piece are made of high-hardness aluminum, and the screws are made of aluminum.
3. Flywheel adopts alloy bracket.
XTR not only contains the characteristics of Deore XT, but also has advanced characteristics that XT does not have.
1.XTR is completely redesigned, and M970 has many major changes. See the introduction of M970 everywhere for details, so I won't go into details here.
2. The backward guide wheel and tensioning wheel are sealed bearings, and all connections are made of ultrahard cold cast aluminum, which is anodized and colored.
3. The gears and bowls of the flower drum are super-polished, and stainless steel balls are used. The shell of the flower drum is made of high-hardness aluminum. The newly improved M970/975 hub seal has a smaller gap between the new four claws and the shaft is made of titanium alloy.
4. The flywheel is made of superhard alloy bracket, and the largest four teeth are made of titanium alloy.
5.770 1 Chain is made of galvanized alloy.
6. The crank is made of superhard cold-cast aluminum, the large and small teeth are cut with 7075 aluminum, the middle teeth are made of titanium alloy, and all screws are made of superhard aluminum.
The spare parts of sports bicycles are highly targeted in both design and collocation, and the principles and details involved can completely become a science. But there is one unchanging rule: suit yourself. If it doesn't suit you, then even the top-grade parts can't play their original role. It's a pity that the most parts in sports bicycles all over the world are produced by a small Japanese company-shimano Ximano. This company is also very strange. It never produces complete vehicles, frames and front forks, but only produces other parts of bicycles, such as speed change, transmission and braking system.
In 2000-3000 vehicles. The correct solution of the speed change system is ALIVIO suite: 8-speed, including: finger dialing (with brake handle, which can save money on buying brake handle), forward dialing and backward dialing. You can also choose to support 9-speed back dialing, and choose Deore or Deore LX. Because an old bird said that if you use 9-speed dial-back, you don't need to change the dial-back in the future. However, personally, there are still many things to be changed in the future. Tooth plate, flywheel, chain, so I suggest you don't use your own brains to configure it. The manufacturer will arrange it for you. In addition, ALIVIO's back dial is not very expensive, and it will not hurt if it is changed in the future. Using this suite will not lead to possible incompatibility problems, because it is generally compatible with the same company. So only one person chose Shimano ALIVIO model 4 10 kit. Do not choose anything else. 3000 cars can also consider 9-speed things, but it is still not recommended. You can buy some other things with the saved rice. Because the most important thing in cycling is to look at people, not cars.
Welcome everyone to clap for what I wrote above. There are no bones in the eggs, but who can guarantee that the hatched chickens have no bones?
Motion system: In the road bike, the wheel is also called the soul of the road bike, but it is actually in the mountain bike. Because cars are rolling, no matter what cars are on wheels. The motion system comprises a central shaft, front and rear shafts, a pressure plate, a flywheel, a chain, a steel ring and inner and outer tires. The main accessories still think that we can consider the things of Shimano in Japan. Some people also suggested using other brands of products, but they still think it is more scientific to use Japanese products. Because most people use it, there is no problem. Absolutely affordable, using all reasonable things. Other brands always have a price factor in it. Not that you can't use anything else.
Axis: Shimano UN5 1 or below (there are many cheap options, such as choosing VP products, but this thing is not easy to break down and not expensive, so buy a better one. Still worth it)
Front and rear axles: you can choose Deore (recommended), Deore LX (better effect) and Deore XT (good things, but the price is a bit high). And JOY belongs to Jiuyu. The price is not much different from Deore XT, but there is a little difference in price and performance, so I won't go into details here. But it is recommended that people who are heavy use JOY's things. Deore XT is a load-bearing structure. Happiness is a Pei Lin structure.
Flower drums are generally called axles and wheels. It's popular now that flower drums have bearings. In fact, the flower drum we use has always been a bearing-ball bearing. Only the marbles and fairways (axle bowls and axles) are self-assembled. At present, the so-called bearing flower drums all use finished bearings. I used to be superstitious about bearing flower drums, but later I gradually found that bearing flower drums were not so perfect. At least in some middle and low-grade flower drums, it is found that the bearing flower drum performs well in the direction perpendicular to the fairway surface because of the use of ordinary ball bearings, but for the lateral pressure, because the fairway is symmetrically designed and the center line is the focus, it will cause slight deformation, indicating that the wheel is unstable under the lateral force. I think only specially designed bearings, plus needles and balls, can solve this problem perfectly. For example, the bearing design of Shimano's top tread. I think this may be the reason why Shimano has been using the traditional marble scheme, but all the above are my personal guesses. In actual loading, sports are generally the mainstay. Using the bearing hub will not cause much problem, but it can prolong the service life of the hub. Pei Lin is said to be exchangeable, but the things inside JOY are still Japanese. Bearing is a very complicated problem, so I won't say much here. If you are interested, you can check the information yourself.
Press plate: Shimano dental plate model m34 1 (this thing is not easy to break, as long as it is durable).
Flywheel: Shimano HG508, i.e. 8-segment flywheel.
Chain: Shimano IG5 1
Steel ring: Sun model CR 18, ordinary stainless steel wire. Correct after riding 1 month. Re-calibration after half a year can ensure a long time. (You can also choose something with two stars.)
Tires: buy a pair of horse brand tires, which can be applied to almost all roads. Buy a new pair of bald tires. Just choose a new inner tube.
Seat: diy bike looks very good, but there is a lot of learning in it. If you don't choose and match well, you will spend more money and be uncomfortable to ride. The following are mainly for ordinary mountain bikes, downhill bikes, road bikes and slopes. When loading a car, it is very important to choose a shelf with the right size first. This includes selecting the frame and placing the vertical saddle on the horizontal saddle. Specifically, the size of the mountain bike frame is relatively tolerant and relatively easy to choose. Height: After the wheel is mounted, the upper pipe should span the vertical frame, and the distance between the upper pipe and the gear should be more than one punch. According to my experience, ten centimeters is the safest. Because if you use the shock fork, this height will be reduced. Besides height, length is very important. Many people say that mountain bikes are too tired to ride. Actually, the length is wrong. Too long a frame will make the upper body lie too low and the arms stretch forward, which can't effectively support the body, so it is very tired. The best distance is to make the angle between your upper body and your arm 90 degrees or less. Of course, you can be older, but you will definitely be tired. This way, the waist and arms will not get tired easily. As for the adjustment of the frame length, it can be adjusted by handlebars with appropriate length and different widths. The third is the position of the saddle. Adjusting the saddle back and forth can also increase the length of the frame. But the effect of this adjustment is obviously that the abdomen and waist are bigger. Comfort depends largely on the position of the saddle. A seat that is too far back (for example, with some seat tubes extending backward) will make the legs and waist fold too much, which will make the waist ache easily on the one hand and make it difficult to exert force on the other. And the front end of the saddle is more comfortable when it is away from the central axis 10 cm. Long-distance running can go a little further. In terms of the framework, besides the above, there are some small details. For example, the shape of the car seat, the type of handlebar and the shape of the car seat: some people think it is wide, soft and comfortable. Actually, it is not. Not as soft as possible. Too soft a cushion will make your pp sink in, and then it will hurt to grind. Otherwise, it will crush the little dd. These are all faults caused by the soft cushion. And the angle of the saddle. According to the book, the level is better. In fact, it is better to lean forward slightly and the front end will be slightly downward. Support pp with ischium instead of pressing the whole pp on the cushion. My cushion is the kind that looks small and a little hard. But it's comfortable and seldom hurts. And the type of handle. There are two main types. Straight handle: it is suitable for long-distance running through the forest with a handle. It is a classic mountain-crossing type. Yanba: Suitable for places with complex terrain and high requirements for handlebar control. But for the swallow handle, the width is generally relatively large, and it is difficult for people with short stature. It is likely that a straight handle will be more comfortable. Moreover, the adjustment and rest of hand posture when going uphill, exerting strength and riding for a long time are not as good as straight handle+paid handle.
1. Buy a seat of 100+. For boys, this is very important. One thing that girls need to pay attention to is to buy a relatively wide seat. Because of the bones, a wider seat has better support for the body.
2. Like vertical handles, horizontal handles, auxiliary handles, sitting poles, subject to price restrictions. Just use ordinary ones. Generally speaking, there is no need to choose something ultra-light. Ultra-light things are still expensive. Of course, the price is still tens of dollars, which is a little more expensive than street stalls.
3. Buy a 40- 100 pedal, and don't approve of using PD (self-locking pedal) or egg beater. Maybe many people are using the two things I mentioned above now. If you get on that thing, you'll have to wrestle with your bicycle shoes in the future. But some people have said that I died early playing DH (speed reduction) with self-locking. Who can guarantee that there is no danger in the cross-country process? When the danger comes, the foot is still connected to the bicycle, which can't be separated and can't protect itself. Haha, I'm afraid of death, but I still don't think I should go to PD. In the process of riding, sometimes I feel that it is really good to have PD, but for safety. I'd better not use it I don't believe in myself. For this 2000-3000 budget. Recommend the brand PD pedal of VP. The price is lower, 1XX.
This is a very important question. Helmets, helmets, helmets, helmets, helmets are life-saving things. You must wear them, and gloves are recommended. And cycling clothes, cycling pants.
After the car is installed, it is a question of maintenance and general application:
Do not move all bearings. Not even lubricating oil. Pay attention to nursing, and it is best to avoid high-pressure water flushing. What needs cleaning is the chain, pressure plate and flywheel. It takes a lot of effort to clean up these. Practice slowly. Just soak the cloth in kerosene (commonly known as fire, water and oil) and wipe it. It is better to have a chain washer for the chain, otherwise it will be very troublesome to clean it. Chain washing machines can be rented, or several people can chip in to buy one. You can clean the chain with engine oil or professional lubricating oil. Small quantity, oiling is also very important. Check the refueling method yourself.
Conclusion:
There are many inaccuracies in the article I wrote above. Please correct me.
I didn't think much about the weight of the car, because 2000-3000 cars are generally around 13XX. Again, riding a bike mainly depends on people. The car is over there, so you can ride it. There are many things to choose from, and the scope is very small. According to me, it is estimated that everyone's car is the same. And what I recommend to you is not necessarily the range of 2000-3000. It is normal to have fluctuations. I hope you can understand that I am not the owner, so the price of things will definitely be wrong. I hope you can understand. That's it. Again (you are welcome to get tired of what I wrote above. There is no bone in the egg, but who can guarantee that the hatched chicken has no bone. Forgive me if there is no picture.
