Good to know: Integrated cockpit

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.

Manufacturer’s manual (PDF)

Corrected values: bar width

47 bar width 420 → 370 mm, 47 bar width 438 → 390 mm, 51 bar width 420 → 370 mm, 51 bar width 438 → 390 mm, 54 bar width 420 → 370 mm, 54 bar width 438 → 390 mm, 56 bar width 440 → 390 mm, 56 bar width 458 → 410 mm, 58 bar width 440 → 390 mm, 58 bar width 458 → 410 mm, 61 bar width 460 → 410 mm, 61 bar width 478 → 430 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
