Dorel Industries that supplies 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 (Questor Partners) in 1998, but the conglomerate went bankrupt in 2001, and was acquired by Pacific Cycle. Dorel Industries acquired Pacific Cycle in 2004. GT itself acquired Auburn Racing and Dyno Products from Bob Morales plus Robinson Racing from the late Chuck Robinson in the late 1980s. GT is directly administered by Dorel although the Dyno label has been resurrected and is part of Pacific Cycle.
GT mountain bikes are often readily identifiable by the "triple triangle" frame design present in most hard-tail
designs. Early BMX frames were also easily identifiable as the top tube
seemed to bisect the seat tube and protrude beyond it by approximately
an inch-and-a-half towards the rear of the frame. This innovative idea
was claimed to reduce the amount of vibration transferred to the seat
from the rear wheel. Later versions would actually have the customary
"GT" letters stamped on the end of the protruding tube.
