Need help with GT Frame
Here is a Chrome GT frame I have cleaned up. Would like to know what it is and year. It has a 18 1/2" top tube. Any help would be helpful.

Re: Need help with GT Frame
Looks like a 91 by the serial number, but the 4130 stamp has me thrown.
It's not a Pro Performer style frame, and I don't think the Vertigos were stamped 4130... and it looks like the race bikes didn't have the balogna cut? So... I'm not sure. ![]()

Thanks for the input. I was leaning towards the 91 date, but stumped on the model.

Re: Need help with GT Frame
It's either a Interceptor or Mach One, more likely a Mach One, just made overseas. 91 by the serial.
I'm sorry I don't kiss a$$.
black and chrome parts, the way bikes should always be.

http://bmxmuseum.com/bikes/gt_bicycles/ … JmXI4afZEU actually none of the 91s listed have the angled cap. I still stick to it being a Mach one
