Faze 3:
Hi fella's

Hopefully there are plenty of GT performer experts on the forum today. Cos I have a chance to buy what I think is an 83 / 84 pro performer.

It has all the early signs of being an early frame, three holes and cut rear drop outs, rear seat tube stays are low & it has no support bar behind the crank case.

What I'm not sure about is the small stamped GT plate behind the seat post, its stamped GT 4130, but the plate looks welded on? Is this right? I can't remember the serial no, any ideas what they would be for this year, so I can check.

Thanks
Mark

In a nutshell:

They came out in Feb 84 with 3 holes in the drop outs and the seat stays meet the top tube in the middle (i.e. they are not level with the top). Forks have 4 holes in the drop-outs.

The Feb 84 was unstamped, stamping started in March/April 84 (GT 4130)...the serial number is on the outside of the rear drop out and will be something like (684XXXX - which would be June 84).

Level seat stays and came in late 84/early 85, with 4 holes and a cable guide on the forks.

Hope this helps!

This is my June 84:
