A freehub is attached to the rear hub of your bicycle. It is a spinning mechanism designed to hold the cassette. Coasting when the pedals are at rest and pedaling are possible thanks to the freehub.

Start by removing the cassette. To remove the cassette:

A threaded headset gets its name from the threaded steerer tube at the top of a fork. The steerer tube is attached to the inside head tube on a frame with an adjustable race. A threaded headset can be identified easily by the quill-type stem that fits inside the steerer tube. This article will discuss repairs and adjustments of a threaded headset.

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

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

Keeping your chain clean is essential, especially if you ride in the rain or other adverse weather conditions. Regular chain maintenance prevents rust and chain stiffness.

There are two camps in the debate over chain lubrication: proponents of lubrication and its opponents. The opponents’ argument is based on the idea that chain lubricants attract grime. When this grime becomes stuck to the chain, the opponents of lubrication believe it causes increased chain wear.

The camp promoting chain lubrication believes lubricants allow for longer chain life and reduced friction. There is little evidence to settle this debate. For more information about lubricating your chain, read on.

A chain “stretches” through regular use. This does not mean the metal literally stretches, but over time the bushings between the plates of the chain wear down, and the chain becomes a little longer. “Stretch” is the main reason avid cyclists replace their chains, but if your chain is rusty or just plain ol’ grimy, it’s not a bad idea to replace it.
