I looked for a GTB for a LONG time before I found my Panasonic, and from what I recall, they're sized small. I may be completely wrong because I've never ridden one, but I nearly bought a 54cm and I'm 5'9. Please don't pay more than $300 for this frameset; the outrageous inflation on the generic track bike is 100% driven by the cult following behind these frames, when in all actuality, they're really just eh framesets. Look for a kinesis Pulse I'd say.

Actually, I just found this and it's telling me I'm dead wrong:

get ahold of the staff at Alpenrose Velodrome in Portland OR, they use GTB's as rental bikes, they should be able to help you out

that thread really doesn't have any useful information in it.
if you know what size bike you ride then you can figure out if the frame would fit if you knew seat tube ctc, ctt, and top tube length and whether the tt slopes any...

Yeah i was looking at the Pulse and the gutterball but Im not a fan of the water bottle holes and I believe the frame is not the same geometry.
I found this one https://newyork.craigslist.org/mnh/bik/1293788027.html its a 56cm. says its a 32"stand over height so im guessing it's mid bb to mid seatpost tube.
