sounds about right for frame size, I would think they used the same headtubes for those frame sizes I mentioned previously. Price is a bit steep though.
Just found this, I'd love to buy but I already have a number of GT's and not enough funding (at this moment)
Looks nice though.
GT Karakoram Elite on eBay
Just found this on eBay, my attention drawn to the unusual chain and modified dropouts to accommodate drum brakes...
Seems quite pricey for what it is..

Okay, fair enough. My 1999 GT Tequesta has a 68mm BB. I recently replaced the bb on that too, so I know from measurement that it is 68mm and took a BB from my Mongoose IBOC PRO SX which is a 1996 model with a Ritchey steel frame.
Here are my 3 GT bikes I currently own. 1/3 of all GT mtb's I owned since 1992

The Zaskar Sport has now had Fox Float RL100 and a 40mm riser bar fitted since this photo was taken.
