GT Ultrabox
GT Bicycles is a large American manufacturer of road, mountain, and BMX bicycles. The company was founded in 1979 by Gary Turner, a welding engineer and Richard Long, a bike shop owner. The company merged with Schwinn in 1998, but the conglomerate went bankrupt in 2001, and was acquired by Pacific Cycle. Dorel Industries acquired Pacific Cycle in 2004. Early BMX frames were easily identifiable as the top tube seemed to dissect the seat tube and protrude beyond it by approximately an inch-and-a-half towards the rear of the frame. This innovative idea actually provided no structural performance, but did seem to be aesthetically pleasing to the overall design. Later versions would actually have the customary "GT" letters stamped on the end of the protruding tube. The company has equipped many successful athletes, including: Thomas Allier, Robert Dewilde, Randy Stumpfhauser,...

The new Ultrabox still has the same frame as the previous years.
