How I read the maker's table
Time trial / triathlon frame with a base bar and integrated stem; four sizes XS, S, M, L. No stem length row (stock_stem_length null). Giant does not say whether the seat angle is effective or actual (null), does not publish front centre (null) and does not state the stack datum (null). Bike Insights' MY2025 Trinity Advanced SL entry (from Giant's GB frameset page) differs from this 2027 page on M reach (431 there, 432 here) and on standover (S 787 and M 815 there, 786 and 814 here); the 2027 page is what is stored.
