In 2008, titanium consumption on sports equipment accounted for 13% of the total in China, with golf heads and golf clubs alone consuming over 1,000 tonnes. Bicycles made with titanium alloy frames are also catching on, and there are nearly 50 companies currently doing business in the titanium bicycles field. For a long time the US has been the biggest titanium bicycle producer and consumer. Spectacle frames are another famous application of titanium due to its extraordinary lightness and less tendency to be less allergenic to skin. Besides, after anodic treatment, titanium can be colorful which makes it even more popular as a frame material.
