Question 2: How to install the joint clamp spring of bicycle chain? The joint clamp spring of bicycle chain should be installed along the rotation direction, so it is not easy to fall off. (That is, when the interface is above, the opening of the clip is backward. That is, when the interface is at the bottom, the opening of the clip is forward. )
Question 3: How to install the mountain bike chain when it falls off? This is very simple. The rear transmission has a relatively small wheel. Touch it down, the chain will become longer instantly, and then help the chain to connect, and the hand that moves the transmission pulley will be OK.
Question 4: Assembling a mountain bike, as the name implies, is a bicycle that can be used for mountain field driving. The first impression is that the appearance is rough, the tires are wide, the shock absorption is rough, and the transmission system is complex. In fact, according to the different off-road intensity, mountain bikes are mainly divided into: off-road (XC), all-mountain (AM), free riding (FR), downhill (DH) and extreme free riding (EFR), as well as mud jumping (focusing on action and mud racing). What we usually see is basically a mountain bike belonging to XC off-road category. Here is a brief introduction to the selection and assembly of this kind of car. In fact, everything is the same. First of all, I need to know that everything I want to assemble needs those basic parts. Then, how to choose and match parts. Finally, you need some simple knowledge and hands-on ability to assemble the purchased parts. Let's start with the basic parts of mountain bikes. Mountain bikes are no different from ordinary bicycles, and consist of the following parts: frame-I don't need to say more, but I need to know the names of the main parts of modern mountain bike frame, as shown below (this is XC frame without rear shock absorber), in which the five-way is used to install the central axle and the tail hook is used to install the rear drive: front fork-fork for fixing the front wheel, modern sports. Bowl set-a round part installed at the joint between the frame and the front fork, with balls or closed bearings inside, which is responsible for the rotation of the front of the car. Generally, there are two types of light mountain bikes: 34MM outer box and 44MM inner box, depending on the type of frame head tube. Generally, the diameter of the cross handle is roughly divided into 25.4MM and 3 1.8MM, which need to be matched with the stem with the same caliber. The thinnest part of the cross handle is 22.2MM, which is sleeved on the handle and held by hand. Connect the metal tube with the horizontal handle vertically and fix the horizontal handle on it. Brake handle-a handle that is caught when braking. Brake-Brake device, used on mountain bikes, is generally divided into V-type brake and disc brake. Disc brakes are divided into mechanical disc brakes (cable-pulling type) and hydraulic disc brakes (the piston is controlled by the pressure of the liquid in the oil pipe to push the brake pad to brake). The braking object of V brake is the rim edge, while the disc brake is the disc. Wheelset-consists of three parts: rim, spokes and hub, in which the hub is also called front/rear axle, which is responsible for wheel rotation. Here, it is emphasized that the hub length of light mountain bike is generally 1 10MM in front and 135MM in rear, with the front axle core diameter of 9MM and the rear axle core diameter of 65438. Generally speaking, the "ringing number" of the flower drum refers to the number of ringing noises heard when the base of the flower drum rotates once. The greater the noise, the smaller the pedaling position, which is suitable for riding with strong movements, such as climbing, cross-country or climbing, but the rotating resistance of the flower drum is greater, while the flower drum with smaller ring number is generally smaller, which is suitable for riding mainly on flat roads and downhill roads. In my opinion, when riding on various roads (excluding extreme cross-country), the 24-36 ring flower drum is the best, which takes into account the low virtual space and high speed, which is why experienced players rarely use the 72 ring chris king flower drum to ride on the flat ground, not only because it is expensive. Central shaft-installed in the five-way connection, connecting the crank and the toothed plate, which is directly related to the pedal. It is mainly divided into square hole central shaft, spline central shaft and GXP integrated central shaft. The specific selection needs to match the central shaft hole of the crank. At present, most parts manufacturers mainly promote GXP integrated shaft-light weight and high strength, but the square hole and spline shaft are actually great to use. Light mountain bikes generally use 68MM (the length of the thicker part except the axle core)-inch thread specification, and heavy vehicles are longer. The number 10X- 12XMM we see on the central axis is the total length of the central axis including the shaft core. The following figure shows the central axis with square hole, the central axis with spline and GXP from left to right ... >>
Question 5: How to install a screwdriver, branches, sticks or something when the bicycle chain falls off? Pull down the zipper and turn it in the direction of the rear wheel, which is opposite to the rotation direction of the chain. It's easy to say, but you may not understand it until you have done it. Try it yourself.
Do not use your hands. It is not easy to break it directly with your hands, and it is easy to hold it with your hands. Roll in the direction of the chain with a screwdriver or stick and get stuck. The chain itself is relatively loose and elastic, and does not need too much force, but attention should be paid to making the chain turn. By turning, the gear will be stuck in place by itself.
Question 6: How to install this mountain bike chain? Please help me. I won't pretend! 100, your car should be upside down now, right? First, put the front pedal gear chain on the low-grade small wheel, and then hang it on the rear wheel from above. There is a slideway support between the rear wheel and the lower tightening wheel, which can be easily suspended along the force.
Question 7: How to disassemble and assemble the bicycle chain? Use chains to guard the guards. If there is no imperial nail aimed at the small iron column at the joint of the chain, it will hit the iron column with the tip of the nail. After the iron column is knocked out, it will naturally be replaced with a new chain.
Question 8: How to disassemble the mountain bike chain with a chain breaker (also called a chain breaker)? Any cutting work can be removed. The principle is to give out the cylindrical things at the link, and the cheap chain beater 10 is more than one piece.
Question 9: How to install the chain of the variable-speed bicycle (dial it later)? Is it broken after all?
Question 10: How to connect bicycle chains? There are small iron pieces selling chains on the bicycle stall, and then go home and connect them with a steel bar with a general thickness, drop a small pin in the middle of one end, and then connect those small iron pieces with that pin!
