--- Quote ---retrogeezer, the frame looks as sweet as a nut matey but are those the correct forks?
i thought not.

Wirewheel,


The frame & forks were supplied like that....my guess is that it's because it's a VERY early one and they were not producing the freestyle fork at that stage.

The rear dropouts also have an extra 'F' stamped on them, race dropouts earmarked for a freestyle frame?


Performers were not on sale until April/may have 84 so this must have been sent over for promo photos or something.

Also, Fiola often rode is performer with these race forks coz he preferred them.

Jazz, retro and Stodgy

Just so I know for future as I am looking to buy one later this year are all your serial# on the rear dropouts and what form do they take (all numbers, some letters etc?)

Stodgy:
The serial number on the early ones (Santa Ana built)  is located on the rear drop out and will be something like '6841121'; where the first 1 or 2 numbers are the month (6), the second two the year (84) and then the next four are the run number. When the production moved from Santa Ana to Huntington Beach in 85 and then later to the far east the serial number convention changed and moved to the bottom bracket.

Again on the the early ones, there should also be 'F' or 'FS' stamped on the drop out (slightly away from the serial number). As Retrogeezer states, this is so the welders could tell the difference between a race and a freestyle dropout. The drop outs started out with 3 holes in the rear and 4 on the forks. This changed to four both ends in 85.

The sloping stop on the top tube should have 'GT' and '4130' stamped on the end. However, the first batch/prototypes were unstamped.

Remember to check the position of the seat stays on the top tube. 84 they were in the middle, 85 they moved up level with the top edge of the top tube...

Freestyle forks were supplied from the first run, however some people prefered race forks (again as Retrogeezer points out) as they were lighter. So many may have left the shops with swapped out forks. As Retrogeezer says, Eddie Fiola perfered this combo, and as such is an accepted configuration.

Below is a really early GT ad from Jan/Feb 84...you can see all the details (including the un-stamped sloping stop and a lovely spelling of Eddie Fiola!):



Hope that wasn't too anal!  ;) :)

Have fun!
