Yield

When an object is bent so far that it does not spring back to its original shape when the stress is removed, it is said to yield.

Yoke

A fitting used on center-pull caliper and cantilever brakes which use a transverse cable. The yoke is the part that connects the main cable to the transverse cable.

This is frequently misspelled as "yolk", which is part of an egg.

Zap ®

An electronic rear derailer made by Mavic.

Zip Tie Zip Tie

A plastic fastener primarily intended for bundling electrical wiring together, but also very useful for securing cables and other items to bicycles. A zip tie consists of a toothed plastic strip with a one-way ratcheting hole at one end. You slide the plain (usually pointed) end of the ziptie into the hole and can pull it tight, but it will not loosen up.

4th hand tools are particularly useful for securing zip ties.

For bicycle applications, avoid using white/clear zip ties, because they are liable to deteriorate due to exposure to ultraviolet radiation when used outdoors.

Zzipper ®

A brand of aftermarket fairings.
