Basic knowledge of bicycle care and maintenance
The tool explains that if workers want to do good things, they must first sharpen their tools. Bicycles must be maintained. Using the right tools is a must. If inappropriate tools are used, it may cause difficulties in work, even bicycle parts. Damage, so the following tools for general maintenance need to be outlined.
Allen wrench: 4mm-8mm/10mm general hardware can be purchased, the car shop has a combination of tools for sale.
Screwdriver: There is a word and cross two, the hardware line can be purchased. (The combination tool contains negligible)
Chain Linker: Use to remove the chain. There are also quick-release fasteners
Open-end wrenches: used for the removal of crankshaft cranks/flywheels, etc. Utility tools crank top wire: used to remove one of the crank tools chain wrench: one of the flywheel tools flywheel detacher: one of the flywheel removal tools hub wrench: for sheet-like openings Wrenches are used to remove flower hubs, typically 13mm to 17mm.
Wire-cutting pliers: The jaws are arc-shaped and do not spread apart when the inner line is cut. (replace the internal use)
Chain Washer: The use of a clean chain is convenient.
Workbench: Used to erect the bicycle for maintenance work.
Wire wrench adjustable ring: adjust the tension of the rim wire. [It is better to give professional technicians debugging]
Lubricants: Although not a type of tool, they are essential for maintaining a bicycle. Three types of butter, chain oil, and general lubricating oil are to be prepared.
1. Quickly clean bikes without skipping the initial flush. Otherwise, in the end you will find that the imprint of the sediment is all over the body and the shiny surface of the frame is scratched. Therefore, before you hold the soapy sponge close to your car, use a hose low pressure water gun to give your car a soft shower and wash it up and down again.
PS Note: High Pressure Hazards If the water pipe throttle is fully opened, it is possible to flush water (water that may contain degreasing agent soap) into the bearing of the bicycle. The lubricating oil in the bearing may be decomposed. If the grease is not added in time after the cleaning is completed, the bearing of the vehicle may be worn out. Caused abnormal noise and other issues.
The right lubricant No matter what bike you wash, the final step is to re-lubricate the chain. If you forget this step, your unprotected chain will quickly rust. However, if there is too much lubricating oil, the chain will attract a lot of dirt. Wipe the excess with a clean rag and apply a thin layer of just the right amount of lubricant to your chain.
By the way, wipe your wheels clean with a cloth. Dust and dirt on the tire rims can affect the braking performance of the bicycle. (V brake ring) Cleaning and maintenance procedures First, clean the drive system. First remove the chain - flywheel - sprocket - dial before and after. Then use a professional chain washer to clean the bicycle chain. With an ultrasonic cleaner, turn the flywheel forward and backward to cook for ten minutes, then use it with a soft-bristle brush and rinse it with clean water (wash off the oil).
Then dry with an air gun. Afterwards, the flywheel was used to disassemble the butter on the guide wheel. Before the carriage was loaded into the car, there was a tool for correcting the tail hook. First, check whether the tail hook was biased or deformed, and then dial the upper dial.
Before cleaning the center axis of the tooth plate, clean up the grease on the five-way shaft, oil the center shaft bearing, and then install it. Then install the flywheel back to the tower base (where it is necessary to do hub maintenance and finish on the upper flywheel).
After the dialing is completed, the rear dial is used to clean the transmission line pipe and the inner line. The inner pipe is oiled (lubricant). The normal transmission line is not used for a long time or there is rust on the rainy day. It is recommended to replace the transmission line. Tubes and interiors, such as the JAGWIRE oil line pipe Teflon line/SHIMANO SP41 line OPTISLICK/polymer line. The final wash hand adjustment is completed.
The order of bicycle cleaning should be from top to bottom, front to back. Car wash tools: detergent / soft brush / towel.
When the bicycle is oiled and the bicycle is oiled, all you really need to find is the parts that can move, that is, the metal parts that touch each other. To use light, bike-specific lubricants, do not use the dirty oil found in your garage. If the oil is too thin, it will quickly evaporate and cannot maintain its effect; if it is too thick, it will remain on it and stick a lot of dust.
Pay special attention to the following sections:
Chain: The chain is the main transmission component on the bicycle, and it is also the place where you need the most protection and most need to be oiled regularly. If you ride in a dusty or muddy environment, you should clean the chain regularly.
Transmission: Your front dial and rear dial are the parts that move the chain when shifting. They consist of numerous small moving parts and also include two guide wheels. You want to keep them clean and lubricated so that they do not stick together or become stiff. Change speed when pedaling, check that the transmission is working properly, and then use lube to lubricate any moving parts, including turning points.
Brakes and shift lines: These lines are responsible for passing your brakes and shifting behavior. If they rust or stick due to not being lubricated in time, you will not be able to stop or change gears smoothly or even at all. This is a major issue. Check them often, especially when you are riding in a dusty or humid environment, add a few drops and re-lubricate.
Brakes and shift handles: They are on the handlebars and are the key components for braking and shifting. Drop 1-2 drops of lubricant on their turning points and on the adjusting nut to ensure proper operation. Then wipe off excess oil to prevent adsorption of dust.
Mechanical brake device: The mechanical brake is the cable brake so it is better to maintain the line core oil lubrication in the line pipe and the inner line. Be very careful in the brake line pipe. Don't let the oil drop to the brake pad. Otherwise, there will be abnormal brake noise. No brakes!
Do not ride a bike for a long time
1, Tire deflation Although the tire will lose air over time, but do not ride for a long time, it is recommended to take the initiative to release the tire gas about half, to 50psi tire pressure as an example, about 30psi can be filled because of full Gas tires may cause cracks in the rim, inner and outer tires.
When you have to ride a bicycle, even if you don't have the air leaked, you must remember to inflate it. You must also check the condition of the tires, whether there are cracks, embrittlement, or other aging conditions. If so, you can quickly change your tires. Oh.
Bicycle tire
2, when the chain is placed in the most loose and often cycling speed, the chain will pull up or relax with the gear ratio; when not riding for a long time, remember to shift to the most loose state of the chain, that is, the big gear plate to be put The position of the smallest disk, and the latter change because of the difference between the forward and reverse, so the method of identification is to look at the guide chain leg of the rear derailleur, it is the most loose state to fold up upwards, so as not to connect the rivets of the chain pieces to the connecting hole of the chain piece. The interior stays open too long, causing the metal to wear out and fail to recover.
The second principle: oil bright
1, screw, chain oil bicycle parts by the screw joints, easy to rust after riding by aging, if you do not ride for a long time, remember to spray anti-rust oil, so as not to rust, riding often with tooth plate, The friction chain of the flywheel is prone to wear, and a layer of anti-rust oil is also required, and the chain is evenly coated while rotating.
2. When the brake wire hole is oiled on an ordinary road, rain or mud can easily accumulate in the brake wire hole of the upper tube of the frame, especially in the lower position of the seat tube. Therefore, when the brake clamp is released, remember to pull the brake wire of the wire hole and apply anti-rust oil to prevent the brake wire from rusting for a long time and damp.
