on the small crossbars of the upper frame stands on PP's and PFT's from the late 80's into the 90's?

Make sense?

Thanks for the help...

guess it didnt make sense. explain better.

On the PFT's there is a "penny roll" on the back frame stander. On the ends are GT logo's...I want to see the 2 different styles when they transitioned.

MNEWXCV- I believe you have an 87- what's that logo look like?

ah ok. 1987 was the first year for the "S" type downtube, thus the first year for the "pennyroll" at the end of the toptube right behind the seatpost. heres a pic:

in 1988, the frame was exactly the same, no changes. same with 1989.

what do you mean by it changing? here are some more pics:






one is an 1987, one is a 1989. pics from ajkbikes.com
