Good to know: Integrated cockpit · 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.
Configurable build (at least partly: the cockpit or bar width, for example). The stock build below is only one of the options.

Corrected values: bar width
M bar width 400 → 360 mm, XXS bar width 400 → 360 mm, XS bar width 400 → 360 mm, S bar width 400 → 360 mm, L bar width 400 → 360 mm, XL bar width 400 → 360 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
