Before the advent of plastic-lined cables, it was necessary to regularly use heavy oil or grease to lubricate the cables inside brake and derailleur cable housings. Thanks to plastic-lined cables, this procedure is largely obsolete. There are however a few points on the modern bicycle that can use an occasional oiling. The small section of cable near the rear derailleur and the sharp bends in cantilever brakes are two points on the bicycle that merit some attention to lubrication.

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

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.

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.

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.

If your cable housing is stiff, shows signs of damage, such as a kink, or is getting old, it may be a good idea to install replacements. Working on cable housings is not particularly difficult but does require the proper tools.

- Wire Snips
