Cold Set

To bend a metal part (without heating it) so far that it exceeds its yield strength, and assumes a new shape.
This is a common procedure for aligning and repairing steel bicycle frames. This buzzword sounds more scientific than "bending."
It is a routine procedure for updating older frames to accommodate newer rear wheels that have wider spacing, when upgrading to modern gearing. This is not recommended for frames made of more brittle materials, such as aluminum, titanium or carbon fiber.
