Geometry, every size, from the maker's table
The tinted row is the size drawn beside it. Press a size to draw it.The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The M drawn to scale from the table, with no build on it. Stack and reach run from the bottom bracket to the top of the head tube; every size is solved from those two. One square is 100 mm.

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 WB and FL 400 every size (fork length, not in the schema). Parameter list image: Model SP-G058; high modulus T1000; T47; tyres to 700 x 50C; frame 1200+/-60 g, fork 450+/-15 g; seatpost 27.2 x 400 mm; 1-1/2 in upper and lower headset; flat mount; 12 x 100 and 12 x 142. Four G058 listings (p4780294, p5030517 "comfort geometry", p5231345 "semi-internal cable", p4783363 with handlebar) print this identical table. OPEN MOULD: the table is identical cell for cell to Rinasclta's GR025 chart (docs/research/geometry/rinasclta-gr025.json), including the XL seat angle 72.5 that looks like a slip for 73.5 (reach 389 plus stack 620 over tan 72.5 gives a 584.5 top tube against the printed 573; 73.5 gives 572.3). The handlebar listing ships the HB-068 bar (docs/research/cockpits/spcycle-hb-068.json). Trail and standover are not published unless named. STACK DATUM: not stated; head tube top assumed. MODEL YEAR: 2023, from the listing title. No Panda Podium, Geometry Geeks or 99 Spokes request was made.
