Butted Tubing

Butted tubing has increased thickness near the joints for strength while keeping weight low with thinner material elsewhere. For example, triple butted means the tube, usually of an aluminum alloy, has three different thicknesses, with the thicker sections at the end where they are welded. The same material can be used in handlebars.
