How I read the maker's table
the brand also sells through an AliExpress store, which was not used). The geometry is an image in the product description on the maker's page; the page embeds that image from Alibaba's image CDN (ae01.alicdn.com or ae-pic-a1.aliexpress-media.com) or from the store's own image bucket, and it was fetched from the address the maker's page gives. Table columns: A "BB center to top of seattube", B "Effective top tube horizonta(l)", C "BB offset" printed negative (recorded as a positive BB drop), D "Chainstay length", E "Seat angle", F "Head angle", G "Front center", H "Head tube length", I "Fork offset", J "Reach", K "Stack". Plus M "Stand-over Heightin" (standover), WB, FL 370 every size (fork length), and L / L1 / N (477/491/515, 631/645/669, 486/500/524), drawn as the base bar reach, the extension reach and the bar stack (not in the schema). Sold with an integrated base bar and stem (drawing: 400/420 wide, 90/100 stem, 72.0 deg, 120, 80 and 235) and extensions; the frame chart is the second half of the image. Bike Insights lists a Tt928 under Tantan Cycling / Seraph, so this may be an open mould. Trail and standover are not published unless named. STACK DATUM: not stated; head tube top assumed. MODEL YEAR: 2026, from the listing title. No Panda Podium, Geometry Geeks or 99 Spokes request was made.
