TREK is headquartered in Waterloo, Wisconsin. The family-owned business was founded by Richard Burke in 1976, starting out in a small steel bicycle factory with just five employees. Within a few short years, the company caught on to bicycle trends and continued to grow. In the early 1990s, it began producing bicycles in a then-new material - Carbone. Today, TREK sets the trends in bicycle development and is also considered a leader in the processing of Carbone. Its proprietary processing technology, called OCLV, has been applied in production with many innovations for more than 17 years. TREK bikes have celebrated success at major world races and have been associated with names such as Lance Armstrong, Alberto Contador, Chris Lieto, Roland Green, Chris Eatough, Andrew Shandro and Travis Brown. TREK is a premium brand you can always rely on.
