Bicycle parts detail
When you are riding a bicycle in the middle of the road, you need to call out to find a rescuer. You have to tell which part is abnormal, and people know what to bring to save you. Not sure? Too many bicycle parts can't remember? It doesn't matter, this name is saved and I can't worry about it.
The frame is the "soul" of the bicycle, and is the decisive factor that affects the ride feeling. When shopping, pay attention to whether the frame size is in accordance with the height ratio of the rider, so as to be light in weight and high in strength.
The common frame materials include aluminum alloy, titanium alloy, carbon fiber, etc.
Head- tube connecting the upper and lower tubes, through which the front fork passes, and the interior of the head bowl set.
Top-head-frame tube for connecting the head tube and the riser.
Down-tube-connect the head tube and the BB shell frame tube.
The Seat Tube-riser length will directly affect the ride feel, and the appropriate frame size should be selected based on the rider's height.
Seat Stay-Connect the upper edge of the riser to the rear hook and the rear axle.
Chain Stay-Connect the five to the rear hook and the rear axle.
Fork-Control the front wheels with a shock-absorbing effect.
Saddle the rider's hips. The selection should take comfort as the main consideration to reduce the compression and friction.
Seat Post-Attach the seat cushion to the frame to support the weight from the seat cushion.
Seat Post Clamp-Hold the seat tube and the frame to facilitate the adjustment of the height of the seat tube. steering system A hub for bicycle travel control.
Handlebar-Connect the tap to control the front fork and control the driving direction. The purpose of the general highway is to lower the upper body so as to reduce the wind resistance and to have a flat road vehicle.
Tape-anti-skid, shock-absorbing effect, and can also prevent sweat from eroding the handle. Brake/ Shift Lever-The brake handle of the road vehicle is formed integrally with the shift handle so as to be installed in the handle in the longitudinal direction.
Head Parts-Bearing parts mounted on the upper and lower ends of the head pipe for fixing the front fork steering pipe to enable the steering of the front fork.
Stem Cap-Protect the part for dust-proof, water-tight and secure the outer cover.
The wheel group bicycle moves forward or stops by contact friction between the tire and the ground, so the material and design of the wheel group will affect the speed and stability of cycling.
The outer frame of the Rim- wheel, the tire fixed to the wheel ring.
The bearing that Hub- drives the wheel ring to rotate, the card type and the lock tooth type, need to match with the corresponding flywheel group.
Spoke- is also known as steel wire, connecting drum and wheel ring, the main arrangement is radiate or cross. Nipple- is a nut that fastens the spoke to the wheel ring.
Cassette body- is used to fix flywheels. Inside is a one-way ratchet, step forward pedal can drive the rear wheel, step back is empty.
Quick Release- fixed wheel group parts, can be quickly opened or closed by the handle. The small groove at the front fork of Dropout- and the end of the rear triangle of the frame can be inserted into the wheel shaft to provide the bearing force between the rear transmission and the frame. Tire- according to different needs, there are a variety of specifications and tire lines to choose from.
The thinner the tire, the smaller the rolling resistance; the wider the tire, the better the shock absorption.
Highway tires are generally divided into open tires and tube tyres, and there are no inner tubes and wheels.
Where Valve- tires are inflated, American air nozzles and French air nozzles are common.
The American nozzle is the same as the steam and locomotive tires and can be inflated at the general garage and gas station.
The French nozzle needs to use a separate adapter.
the transmission system
The transmission system is like the heart of a bicycle, and is the force to drive the bicycle to advance.
These components are subjected to a tread force, which is more likely to be worn by the erosion of sewage or sediment due to the fact that the height is closer to the ground, and therefore regular maintenance and inspection is of considerable importance.
Pedals-Pedals that have a direct force on both feet to push the bicycle.
In addition to the pedals which are suitable for various types of vehicles, a lock with a lock shoe is provided.
Crank-connect the lever of the five-way and the pedal, and transmit the pedal force to the chain.
Chainring/ Chainwheel-Large gear set connected to the right crank.
Bottom Bracket (BB)-A combination of parts connecting the large plate, the crank and the frame.
Chain-connect the pressure plate with the flywheel to transfer the energy to the rear wheel to advance the bicycle.
The flywheel Freewheel/ Cassette-is combined by a plurality of gears and is placed on the base of the rear wheel ratchet (tower base).
Front Derailleur-Controls the transition of the chain between the pressure plate teeth.
Rear Derailleur-Controls the transition of the chain between the flywheel teeth.
The Derailleur Cable-connects the speed-change handle with the transmission.
The braking system
controls the front and rear wheels to slow down and stop the bike safely.
Caliper Brake- uses movable parts to connect brake blocks to slow or stop the wheels.
Highway cars are commonly used as type C brake clamps (abbreviated as C clips), and (Disc). Is also used for disc brakes.
Brake Block- clamp the wheel frame to slow down or stop the wheel.
Brake Cable- connects the brake handle to the clamp.
