Gooseneck or Stem

Stems are generally one piece with the gooseneck on cruiser bikes. They come in different diameters and lengths. The size needed in diameter is determined by the fork. A special shim can be purchased and used when the stem is smaller then the fork. Generally one piece with the stem but can be separate and bolt onto the stem as with BMX and Mountain bikes. Goosenecks made for BMX bikes can make a neat custom feature on a cruiser but some are intended for 7/8 handle bars and wont clamp nicely on the 1″ bulge of most cruiser handlebars.
