Tri Bike Fit
Good luck, trial and error. What might sound right, might not feel right.
Seems like you are using two different terms for the initials TT....top tube and time trial. From what you are implying I believe you are saying you are looking for a tri bike and asking if there are specific charts. Answer is no.
top tube measurement has some correlation to torso but flexibility, bike (as opposed to frame) reach and stack also has input into it.
further, your last post referred to elbows at 90 and you prefer to be stretched out. That is incorrect, when you are riding ITT, TTT, or triathlon, you will want to utilize your skeletal structure to carry your weight rather than "be stretched out" using musculature. It's not necessary 90 but the measurement is usually 100> angle >87
