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 Schrader valve is the type you will find on an automobile. Schrader valves are still used in some bicycle applications, but have become less popular because their size requires the drilling of a larger hole which significantly weakens narrow rims. The spring mechanism that keeps air inside a Schrader valve is also problematic for riders using compact pumps. A Presta valve can be identified by its smaller diameter and the locknut that is permanently attached to the tip of the valve.

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

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.

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.
