A truss structure, e.g. a bicycle frame, is formed with a truss structure node 4 having inner and outer collar walls 8 and 10. This provides a clevis 12 to receive a strut wall of a hollow strut 6, creating a double lap joint. Additive manufacturing may be used to create a deep clevis 12 with a thin inner 8 and outer collar 10 wall. An adhesive injection port 16 may be used to insert adhesive 14 into the base of the clevis 12, or a syringe may be used, following degreasing and roughening of the joint. Adhesive 14 may be squeezed and flow between the strut wall 6 and inner 8 and outer 10 collar wall during assembly. The inner 8 and/or outer collar wall 10 may be tapered to reduce peeling of the double lap joint. Structure 6 may have a circular or non-circular cross-section (e.g. elliptical or square, figs 5 & 6). The strut wall 6 and clevis 12 may have a matching non-uniform shape.
