Bicycle Parts Diagram Quiz

Bicycle Parts Overview

• Rim: The outer circular part of the wheel that holds the tire in place.
• Front Hub: The central part of the front wheel where spokes meet and it allows the wheel to rotate on the axle.
• Front Disc Rotor: A flat metal disc attached to the wheel that works with the brake to stop the bicycle.
• Front Disc Brake: A braking system that uses a rotor and caliper mounted on the front wheel to provide stopping power.
• Suspension Fork/Front Shock: The part of the front wheel that absorbs shock and provides stability on uneven terrain.
• Handlebar: Horizontal bar that allows the rider to steer the bicycle.
• Handlebar Stem: Connects the handlebar to the bike frame, adjustable for height and angle.
• Headset: Bearings and cups that allow the fork to rotate smoothly within the head tube of the frame.
• Grips: Rubber or foam coverings on the handlebars for better control and comfort.
• Rear Shock: A suspension component at the rear of the bicycle that absorbs impacts to improve ride comfort.
• Front Derailleur: Mechanism that shifts the chain between the front chainrings.
• Rear Derailleur: Device that moves the chain across the rear gears to change the bike's speed.
• Rear Hub: Central part of the rear wheel, similar to the front hub, it's where the spokes converge and enables wheel rotation.
• Rear Cassette/Gears: Cluster of gears on the rear wheel that allows for varying levels of resistance while pedaling.
• Rear Disc Brake: Similar to front disc brakes, providing effective stopping power from the rear wheel.
• Seat Post: The tube that supports the seat and can be adjusted in height for the rider's comfort.
• Seat: The part where the rider sits, often cushioned for comfort during rides.
• Tire: Rubber covering on the rim that provides traction and absorbs road impacts.
• Inner Tube: Inflatable tube inside the tire that maintains air pressure and supports the structure of the tire.
• Gear Shifters: Controls that allow the rider to change gears easily for different terrains.
• Brake Levers: Handles on the handlebars that the rider squeezes to engage the brakes.
• Frame: The main structure of the bicycle, making it a rigid body that holds all components together.
• Shift/Brake Levers: Integrated controls for shifting gears and activating brakes for convenience.
• Drop Handlebars: Curved handlebars that allow for a more aerodynamic riding position, common in racing bikes.
• Top Tube: The horizontal tube connecting the head tube to the seat tube, part of the bike's frame.
• Down Tube: The tube that connects the top tube to the bottom bracket, supporting the front of the bike.
• Head Tube: Vertical tube that houses the headset and connects the front fork to the frame.
• Seat Tube: Tube that supports the seat post and connects the seat to the frame.
• Seat Stay: Rearward tube that connects the top tube to the rear fork, adding structural support.
• Rear Brake: Brake system located on the rear wheel to control speed and stopping power.
• (Gear) Cassette: The set of cogs or gears on the rear wheel that the chain moves across.
• Chain: Series of interconnected links that transmit pedal power to the rear wheel.
• Chainstay: The part of the frame that runs parallel to the chain and connects the rear wheel to the bike's frame.
• Front Chainring: The toothed ring at the front that the chain wraps around, determining pedaling difficulty.
• Pedal: The foot-operated lever used for propelling the bike forward.
• Crankset: The component that connects the pedals to the bike and translates the power from pedaling to the drivetrain.
• Spoke: Lightweight rods that connect the wheel rim to the hub, providing structural integrity.
• Hub: Central part of the wheel that connects the spokes and allowing for rotation.
• Fork: The part of the bicycle front that holds the front wheel and connects to the frame.
• Front Brake Caliper: Clamping component that holds the brake pads against the rotors when engaged, providing stopping power.
