GT Bicycles

GT Bicycles was started in the garage of Gary Turner in 1979. Like several iconic firms that began around that time, Gary Turner and partner Richard Long were looking to make better BMX bikes for Turner's kids. The firm grew, eventually making a complete line of BMX, mountain and road bikes.

The company became a roaring success. It famously made the high-performance "Superbikes" for the 1996 American Olympic team. GT has sponsored and equipped BMX, mountain and road racing teams. Among the road racing teams GT sponsored was the famous GT/Lotto-Adecco team in the late 1990s.

GT bikes are famous for having seat stays parallel to the down tube that are welded to both the seat tube and top tube, which GT calls "Triple Triangle". It is a design with a long history that GT has made its own.

Where the power ends up, the Shimano 9-speed cluster. Note the derailleur shows almost no use.
