I like to get a modern Gt PFT frame with a modern geo. I like the look of the old one but not the feeling of my Kgb frame.  It feels so strange to bunnyhop or ride my currend bike in the skatepark. But i dont want to have 2 bikes. I had build up a 80s Gt last year and wondered how big it was even with a 18.75 TT. So hard to do cliffhangers on it. My other KGB i had was 19.6 and was also smaller than that one. So strange. I think i may get a WE bicycles Gt frame with 19.5 tt and smaller rear end. Maybe a steeper seat tube brings the seat forward and the pedals more to the back so jumping feels better. Like the 19.5 tt feels longer with the steeper seat tube. What do you think?

The GT Pro Freestyle tour had like a 14.7" rear.


So a 12.8-13.2 new geo rear with a 19.5 TT is actually shorter than a 87 Pro Freestyle Tour

Not the wheelbase. The feel of it standing on the pedals.
