Hi Sam, I'll break out the magnifying glass and let you know what I can see. Tnxs for the offerIs that frame number U00230608? If you confirm it's correct, I'll check it on my list.
Just under the seat tube / top tube junction there is a decal on the seat tube which states "100% Crmo MTN tubing". This might mean main triangle only as per your suggestion.Apex is usually True Temper AVR with double butted rear end/stays. The Ascent is usually AVR main frame & non specified rear stays. I would hazard a guess this may extend to fork blades also.
Axis was always OX tubes. The Axis & Apex shared the TT-lite tubeset for 94/95 if I am not mistaken.
