All About Bicycle Parts

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) October 11, 2009 -- Perfect synchronization in the functioning of all the parts is essential for the efficient working of the bicycle. Modern day bicycles include many new elements, but a standard bicycle has the same main parts.
The basic parts of a bicycle comprise; the frame: A bicycle’s frame is made up of many tubes welded together.
The wheels: wheels include a hub, the spokes, metal rim and rubber tyres.
The brakes: they include the actuators on the handlebar, brake cables, brake pads and calipers.

The chain and gears: they consist of the front chain wheels, the rear freewheel, the shift levers on the handlebars and the cables. Other bicycle parts include the seat, seat posts, handlebars, handlebar stem, bicycle lights, dynamos, cranks, and pedals.

Gears and ball bearings
Most racing bicycles have gears. Gears adjust the direction of rotation. Multiple gears on a bicycle helps change the distance the bicycle moves forward with each stroke of the pedal. A mountain bike has 24 gears. Chain wheels are the gears at the front. Most bikes have 2-3 chain wheels. There are front and rear derailleurs to change the gears.

Ball bearings in a bicycle serve to reduce friction. Ball bearings are found in the front and rear hubs for the wheels, the pedals, the fork tube, the bottom bracket and in the freewheel. Expensive bicycles have sealed bearing cartridges that don’t need lubrication.
