When you ride a bike badly on the way, you need to call out for help. You have to tell which parts are abnormal, so people will know what to bring to save you. Not clear? There are too many bicycle parts to remember? It doesn't matter, save this name by referencing it, and look at the picture to avoid trouble.
frame
The frame is the "soul" of bicycle, and it is also the decisive factor that affects riding feeling. When purchasing, we should pay attention to whether the frame size meets the height ratio of the rider, with light weight and high strength as the main requirements. Common frame materials are: aluminum alloy, titanium alloy, carbon fiber, etc.
Head Tube－-connecting the upper tube and the lower tube, through which the front fork passes, and containing the head bowl set.
Top Tube－-the frame tube connecting the head tube and the riser.
Down Tube－-connect the head tube with the five-way frame tube.
Riser Seat Tube－-the length of the riser will directly affect the riding experience, so the appropriate frame size should be selected according to the rider's span height.
Upper rear fork Seat Stay－-connect the upper edge of the riser to the rear claw and the rear axle.
Lower rear fork Chain Stay－-connect the five-way to the rear claw and the rear wheel axle.
Fork-the front fork controls the front wheel, which has the effect of buffering and absorbing shock.
Seat cushion Saddle－-supports the rider's buttocks. Comfort should be taken as the main consideration when selecting, so as to reduce compression and friction.
Seat tube Seat Post－-connects the seat cushion with the frame to support the weight from the seat cushion.
Seat pipe clamp Seat Post Clamp－-clamps the seat pipe and the frame, making it easy to adjust the height of the seat pipe.
Steering system
Hub of bicycle travel control.
The driver connects the Handlebar－-to the faucet, which is used to control the rotating front fork and control the driving direction. Generally, road vehicles often use curved handles in order to lower the upper body to reduce wind resistance, and there are also flat road vehicles.
Handle Tape－-with anti-skid and shock absorbing effects, it can also prevent sweat from eroding the handle.
Brake/Shift Lever－-The brake lever and shift lever of road vehicles are formed into a whole and installed on the handle longitudinally.
Head Parts－-bearing parts installed at the upper and lower ends of the head pipe to fix the steering pipe of the front fork so that it can turn and move.
Upper cover stemcap-protection part, which is used to prevent dust, water and fix the outer cover of the stem.
Brake system
Control the front and rear wheels to slow down the bicycle and stop it safely.
Brake clamp Caliper Brake－-use movable parts to connect brake blocks to slow down or stop wheels. C-type brake clamps (C clamps for short) are commonly used in road vehicles, and Disc brakes are also used.
Brake Block－-Clamp the wheel frame to restrain the wheel from rotating, so as to slow down or stop.
Brake Cable－-connecting brake handle and clamp.
Transmission system
As the heart of a bicycle, the variable speed transmission system is the power to drive the bicycle forward. These parts bear the trampling force, and because they are close to the ground, they are easily worn by sewage or sediment erosion, so regular maintenance and inspection are very important.
Pedals-Pedals on which both feet directly apply force to push the bicycle. In addition to the pedals suitable for various types of vehicles, there are also locking pedals matched with locking shoes.
Crank－-the lever connecting the five-way and the pedal, which transmits the pedaling force to the chain.
Pressure plate Chainring/Chainwheel－-a large gear set connected to the right crank.
Five-way/Bottom Bracket (BB)－ for short)-the combination of parts connecting large plate, crank and frame.
Chain－-connects the pressure plate with the flywheel, and transfers energy to the rear wheels to make the bicycle move forward.
Flywheel Freewheel/Cassette－-composed of multiple gears, placed on the rear wheel ratchet (tower base) seat.
Front Derailleur－-the control chain is switched between the pressure plate teeth.
Rear Derailleur－-the control chain switches between flywheel teeth.
Gearshift line Derailleur Cable－-connects the gearshift lever with the transmission.
Wheels
Bicycles move forward or stop depending on the contact friction between tires and the ground, so the material and design of wheel sets will affect the speed and stability of riding.
Rim-the outer frame of the wheel, and the tire is fixed on the rim.
Flower drum Hub－-the bearing that drives the rim to rotate, which is divided into clamping type and locking type, and needs to be used with the corresponding flywheel set.
Spoke spoke-also known as steel wire, connects the hub and rim, and its main arrangement is radial or cross.
Ribbon cap Nipple－-a nut that secures spokes to the rim.
Ratchet base Cassette body－-used to fix flywheel. There are unidirectional ratchet teeth inside. Stepping forward can drive the rear wheels, while stepping backward can idle.
Quick Release－-parts of fixed wheel set, which can be quickly opened or closed by handle.
Hook claw (front/rear) Dropout－-a small groove at the end of the front fork and the rear triangle of the frame, which can be inserted into the wheel axle to provide the bearing force of the rear transmission and the frame.
Tire－-according to different requirements, there are various specifications and tread patterns to choose from. The thinner the tire, the smaller the rolling resistance; The wider the tire, the better the shock absorption. Road vehicle tires are generally divided into open tires and tube tires, and tubeless tires and wheel sets.
Valve-the position where tires are inflated. American and French valves are common. American air nozzle is the same as automobile and locomotive tires, and can be inflated in general car dealers and gas stations; Additional adapters are required for French nozzles.
