A mountain bike is the one thing you need before you go mountain biking. A mountain bike contains many parts, which will be covered below:
1. Bottom bracket – This attaches the crankset to the body of a bike.
2. Brake cable – This is the cable that connects the brake lever to the brake mechanism.
3. Brake lever – The lever on the handlebar to activate the brakes. The left side is the front brake and the right side is the rear brake.
4. Chain – The circular set of links that transfer power from the chain ring to the cogs.
5. Chain ring – The toothed rings that attach to the crank to hold the chain.
6. Crank – The lever that extends from the bottom bracket to the pedal, transferring the power to the chain rings.
7. Derailleur – The mechanism for moving the chain from one cog to another.
8. Down tube – The section of frame that extends downward from the stem to the bottom bracket.
9. Front shock – The shock absorber on the front fork.

12. Hub – The center part of the wheel that the spokes are attached to.
