Good to know: Integrated cockpit · From the frame’s tech sheet · Configurable build
Integrated cockpit (a one-piece bar and stem) on at least one build. Changing the length means replacing the whole cockpit, and not every length exists. Check which length the bike actually ships with before you buy.
From the frame’s tech sheet. BB86 bottom bracket, tyres up to 35 mm. Groupsets: Shimano mechanical and Di2 2× only, SRAM AXS 1× and 2×, Campagnolo EPS 2× only. The D-shaped aero seatpost (AER10) is 350 mm on sizes XS to M and 400 mm on L, and needs at least 100 mm in the frame. Headset IS42/28.6 top and IS52/40 bottom. The Forza Cirrus Pro integrated cockpit comes with a 90, 100, 110 or 120 mm stem, in a straight (reach 75, drop 130) and a flared version (reach 70, drop 120, flare 16°); it comes with 40 mm of spacers. Size XXS appears only in the tech sheet, not on the website.
Configurable build (at least partly: the cockpit or bar width, for example). The stock build below is only one of the options.

Manufacturer’s data sheet (PDF)
Corrected values: bar width
M bar width 420 → 380 mm, S bar width 400 → 360 mm, L bar width 420 → 380 mm. The manufacturer gives two widths for these bars: at the hoods and at the drops (the bars are flared). I’d entered the width at the drops by mistake. It’s now the width at the hoods, as for every other bike on sedimi.bike. The bar position isn’t affected. Corrections
