I was a GT bicycles rep from 89 to 99. All of the frames they made are 'racing" geometry. usually 73 degree angles. Not to aggressive. They were alway stiff frames. They were all made in taiwan except for the highest end models. 7000 series were over seas bicycles, 6000 series were made in Santa Ana. They came in ball burnished and brushed aluminum. Usually the edge model was ball burnished and made here. Others were overseas. Show some pics. Also, an authority is Kevin Sande. He has a facebook page for GT bicycles.. Check him out as well.

Thanks
