A surface decoration structure includes an undercoat film, a silver mirror film layer, and a topcoat film formed on a surface of a substrate. The silver mirror film layer includes a film of stacked nanometer-sized silver particles having surfaces coated with a polymer dispersing agent, and the topcoat film includes, as a solvent, at least one member selected from the group consisting of an aliphatic hydrocarbon compound, an aliphatic hydrocarbon compound solution including 10% by mass or less of an aromatic compound, and diisobutyl ketone. The undercoat film and/or the topcoat film may include a corrosion inhibitor. The silver mirror film layer may further include a corrosion inhibitor. The surface decoration structure includes the silver mirror film layer with improved luster and corrosion resistance.

A resin molded body includes a body having a surface, and a decorative sheet adhered to the surface of the body. The decorative sheet has a metallic luster layer, a transparent protective layer positioned on an outer side of the metallic luster layer, and a welding layer adhered to the surface of the body. The body is formed from a fiber-reinforced resin having reinforcing fibers defining an anchor structuring layer such that the reinforcing fibers of the body bite into the welding layer at a boundary portion between the welding layer and the body such that the boundary portion has an uneven shape.

A bicycle rim comprises a tire-attachment portion, an inner peripheral portion, a first side portion, a second side portion, and a first non-contact printed deposit. The inner peripheral portion is provided radially inwardly from the tire-attachment portion with respect to a rotational center axis of the bicycle rim. The first side portion includes a first curved surface. The first non-contact printed deposit is at least partly provided on the first curved surface. A first tangential line is defined on the first curved surface in which the first non-contact printed deposit is provided. A first surface angle is defined by the first tangential line and a reference plane perpendicular to the rotational center axis. The first surface angle is larger than 30 degrees.

A composite bicycle component includes a first member made of a metallic material. The first member has a surface with a first dimple. The first dimple includes a second dimple that is formed on the first dimple. Preferably, the composite bicycle component further includes a second member attached to the first member so that a part of the second member extends into the first and second dimples.

Composite bicycle component

A bicycle component comprises a base member and a first alumite layer. The base member is made of an aluminum alloy. The first alumite layer is provided on the base member. The first alumite layer has a thickness that is equal to or larger than 1.0 &#x3bc;m.

A corrosion resistant part comprises an aluminum alloy part main body, an alumite layer disposed on the part main body, and a corrosion resistant layer disposed on the alumite layer. The part main body has a normal portion and a flawed portion so that the alumite layer comprises a normal portion alumite layer formed on the normal portion and a flawed portion alumite layer formed on the flawed portion, and the corrosion resistant layer comprises a normal portion corrosion resistant layer formed on the normal portion and a flawed portion corrosion resistant layer formed on the flawed portion. The normal portion alumite layer has a thickness between approximately 0.5 microns and approximately 5.0 microns. The corrosion resistant layer is formed from an ionic resin and has a thickness less than or equal to approximately 5 microns.
