Cantilever
Brakes

Although cantilever brakes are considered by many to be outdated technology, superceded by the likes of caliper brakes and disc brakes, they still have a relevance on today's bikes. Cantilever brakes are extremely lightweight and are usually cheap as far as components go. For cyclocross bikes, they offer excellent clearance around the tyre, helping to avoid clogging from the typically muddy conditions. To use cantilever brakes on your bike, you must have the correct mounts, so you can't add cantilevers to a disc brake road bike, for example.
