It's not only oil and gas prices that are jumping each month. Titanium, carbon fiber, and to a lesser extent, aluminum bikes are climbing like a cyclist on Alpe d'Huez.
Why? You can thank the aircraft manufacturing industry. Demand for newer and better planes and other flying craft is going "up, up, up". Which, in turn, means the demand for precious metals and synthetic fibers used throughout the plane-making process like titanium and carbon fiber, also "takes off". Titanium is made by refining and melting an ore extracted from sand--raw materials equal fixed supply.
