Abstract: A brazed bicycle frame and method for making. At least two bicycle frame half-shells are fabricated. A filler metal is then placed between the bicycle frame half-shells to form a two-part hollow frame section. The two-part hollow frame section is inserted into a hot volume at a temperature higher than the melting temperature of the filler metal but lower than the melting temperature of the two bicycle frame half-shells. The filler metal is allowed to melt. The filler metal is then allowed to cool and harden to form a rigid joint. Preferably, the bicycle frame half-shells each have a flange that facilitates alignment fixturing and assembly of the two-part hollow frame sections. Also it is possible for the filler metal and the bicycle frame half-shells to be placed in an extruded or formed grooved section. The grooved section also facilitates alignment fixturing and assembly of the two part hollow frame sections, and helps to strengthen the braze joint.
