What does the front derailleur do?
|
|
The front derailleur pushes the chain from one chainring to another. It works very similarly to the rear derailleur by shifting the chain so that it falls onto a smaller chainring, or so that is pushes against a larger chainring and eventually catches the teeth. A properly adjusted front derailleur will shift between chainrings without allowing the chain to slip off in either direction.

What does a rear derailleur do?
|
|
The rear derailleur is designed to move the chain up and down on the sprockets (or cogs) connected to your rear hub. Together these cogs are known as the rear cassette. By moving to a cog with fewer teeth, the derailleur gives the rider a faster (or higher) gear which is appropriate for flat areas or descents. By moving to a cog with more teeth, the derailleur offers a gear more appropriate for climbing hills (or a lower gear).

What does a freewheel do?
|
|
A freewheel makes it possible to coast on a bike. When you are pedaling, the freewheel engages the sprockets, but it allows the rear wheel to turn when the pedals are at rest.
|
|
|
|
|
- A bicycle stand is always recommended
- A special tool designed specifically for your particular freewheel, known as a “freewheel puller”
- An adjustable wrench compatible with the hexagonal section of your freewheel puller
- You may need a bench-mounted vice for particularly stubborn freewheels

What is a chainring?
|
|
Chainrings are the one, two or three large sprockets attached to the drive side of your crankset. Shifting from one chainring to another gives you different gearing options while riding.
|
|
|
|
|
A chainring is ready to be replaced when its teeth have become worn from use. Typical signs of the need for replacement are slippage of the chain and (rarely) excessive noise.

What kind of brakes do I have?
|
|
The easiest way to differentiate between a caliper brake and its counterpart, the cantilever brake, is to look where the brake is attached to the frame of your bicycle. If the brake is attached at two points, you have a cantilever brake. If the brake is attached by a single, centered bolt, you have a caliper brake. This article will discuss adjustments of the caliper brake.
