GT sizing and rider length

Hi there! Caught the GT flue and I'm currently infecting others. Looking at a Karakoram for a friend. This looks like a size 18", right? What is the recommended rider length for this size?

And oh, model year would be of interest! Could it be a 1996? Do they have 1 ⅛″ threadless headsets?
 
Not sure from the angle, but it looks like it could be an 18", which would measure about 20.5" C-T.

They do have 1 ⅛″ threadless headsets, but I can't identify the year for the newer ones.

Thanks for the threadless info!

It's not a 96. Looks like a 98. Note the similarity of the fonts of the decals, in these images. A 98 GT Bravado and a 98 Zaskar.

It could be a 16" or 18". Your friend should probably try it in person.

Mid-to-late 90's, GT's have a great geometry imho. Naturally, the geometry of these frames is aggressive and sporty. Your ass is higher up than the handlebars, and you get into this low, focused, aggressive stance. I love it. However, the more seatpost you use, the more uncomfortable this position becomes. I am 6'1" with long legs, and could not fit comfortably on an 18". Had to use alot of seatpost, and even with 2" riser bars, it didn't work. The angle from saddle to handlebars was too sharp, and it hurt my neck. For GT's, I think it is very important that you fit the frame, without using excessive seatpost.

The head tubes for the 16" and 18" are small. (Not the case for a 19" or 20" though). The top tubes are also short. Yet the seat tube is tall relative to the frame. For someone like me, with long legs, and a small torso, this was excellent geometry. A 19" GT frame, with a 1" or 1.5" riser bar, was perfect for me.
