BICYCLE ANATOMY

1. Seat Stay: The part of the frame that connects the top of the seat tube to the rear dropout. It usually intersects the seat tube near where the top tube joins the seat tube.
2. Front Derailleur: The mechanism that moves the chain from one chainring to another (found above the bottom bracket).
3. Frame: A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. A tube of metal designed to support the bike and its rider, the frame is generally made of aluminum or titanium alloy. Higher end bikes may have carbon fiber frames. All other bike parts are connected to the frame.
4.Headset: The components (including the ball bearings) that allow the handlebar to rotate and steer the fork.
5. Head tube: The head tube contains the headset, the interface with the fork. In an integrated threadless headset, the bearings interface directly with the metal surface on the inside of the head tube.
6. Fork: The fork connects the front wheel and the handlebars to the bike. Front Suspension Fork - holds the front wheel and provides shock absorption so the rider can keep the front wheel on the ground and maintain steering control over the bike.
7. Dropouts: The slots on the frame and fork that holds the wheel axles.
8. Cassette: Toothed cogs that make up the gears (attached to the rear wheel).
9. Rear Derailleur: The mechanism that moves the chain from one gear to another.
10. Chainstay: A section of the frame that connects bottom bracket to rear dropout.
11. Bottom Bracket: The bottom bracket includes the pedal axle and bearings.
12. Chainrings: Toothed rings thatdirectly connect to the crank.
13. Crank: Connects the pedals to thechainring.
14. Pedal: Types of Pedals
15. Down tube: Frame tube thatconnects the bottom bracket to the Head Tube.
16. Handles: Handles are placed atthe ends of handlebars for shifting and braking, although pedal brakes do still exist on many children's bikes. Handles are also important to steering and maneuvering bicycles.
