Seka Spear

Frameset with SEKA's Rapier one-piece integrated handlebar: the maker's page says widths 360 to 415 mm and stem lengths 80 to 130 mm, "19 sizes to choose from freely" (the Rapier size table on the maker's site is an image, https://www.sekabikes.com/wp-content/uploads/2024/10/Rapier-%E5%B0%BA%E5%AF%B8-EN-33.png, not read here). The development manual says "19 integrated bar sizes, 2 seatpost sizes" (two seatpost offsets). Frame: RDC layup 685 g or Standard 780 g (729 g +/-35 g M size Shadow Black painted), BSA threaded 68 mm bottom bracket, headset bearings upper and lower 49.5x40.5x6.5 mm 45/45 deg, axles front 118.6 mm M12xP1.0 and rear 165.2 mm M12xP1.5, max tyre 32 mm actual, saddle clamp for 7x7 / 7x9 / 7x10 / 7x11 rails, 700c. Stem angle, bar reach and drop, spacer heights, max spacer stack and top-cover height are not published on the pages fetched. stock_stem_length / stock_bar_width null (bar size is a buyer's choice).

page 25 carries the table as text, so every number was extracted by script from the PDF text layer, not read from a picture, and checked against a 2x render of the page. SIZES: SEKA's "5+2 non-linear geometry": five regular sizes XS/S/M/L/XL plus two Racing sizes MR (between M and L: more reach than M, less stack) and LR (between L and XL); the table order is XS, S, M, MR, L, LR, XL and is kept. Consistency check (mine, not published): sqrt(FC^2 - H^2) + sqrt(RC^2 - H^2) reproduces WB within 0.5 mm on every size (XS 565.2 + 403.3 = 968.5 vs 969; XL 603.7 + 403.6 = 1007.3 vs 1008). MODEL YEAR: not stated in the PDF or on the page; the manual was uploaded 2024-05 and the Spear launched in 2024; null. Category aero road (the maker: aerodynamic race frame, "Air Drag -6 W" vs the Exceed). No aggregator consulted.
