A bicycle comprises a frame. A portion of the frame includes a substrate and a layer of nano-crystalline material extending over at least a portion of the substrate. A conductive interface is disposed between the substrate and layer of nano-crystalline material for improved adhesion of the layer of nano-crystalline material to the substrate and improved impact performance of the frame portion.

Nano-metal bicycle frame and related components

A method and apparatus for co-curing a multiple material golf club head is disclosed herein. The club head preferably is composed of a metal face component and an aft-body composed of a plurality of plies of pre-preg material.

Apparatus and method for manufacturing a multiple material golf club head

A golf club () having a club head () with a face component () and an aft body () is disclosed herein. The face component () has a striking plate portion () and a return portion (). The aft-body () is composed of a crown portion (), a sole portion () and optionally a ribbon section (). The face component () is composed of a metal material, and the aft-body () is composed of a non-metal material such as a composite material or a thermoplastic material. The striking plate portion () preferably has an aspect ratio less than 1.7. The striking plate portion () preferably has concentric regions of thickness with the thickness portion in the center (). The club head () has a volume in the range of 290 cubic centimeters to 600 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a striking plate portion () surface area in the range of 4.00 square inches to 7.50 square inches. The golf club head () has a coefficient of restitution greater than 0.81 under test conditions such as the USGA test conditions specified pursuant to Rule 4-1e, Appendix II, of the Rules of Golf for 1998-1999.

Multiple material golf club head

The iron golf club head () of the present invention is preferably composed of three main components: a main body (), a central member () and a mass member (). The Mass member () is preferably composed of a high density material such as a nickel-tungsten alloy. The central member () is preferably composed of a lightweight, non-metal material. The main body () is preferably composed of a titanium alloy material. The iron golf club head () preferably has high moments of inertia Izz and Ixx, and a low center of gravity.
