About HEAD Bikes

HEAD was founded in 1950 by Howard Head, the inventor of the first metal ski. It is now a leading global manufacturer and marketer of premium sports equipment, including bikes. That must feel pretty good for a guy who was bullied ruthlessly about his name. But look on the bright side, Howard. At least your parents didn't name you Richard.
