BMC Roadmachine 01 (2027)
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.

Corrected values: bar width
47 bar width 435 → 390 mm, 47 bar width 436 → 400 mm, 51 bar width 435 → 390 mm, 51 bar width 436 → 400 mm, 54 bar width 435 → 390 mm, 54 bar width 436 → 400 mm, 56 bar width 436 → 400 mm, 56 bar width 455 → 410 mm, 58 bar width 436 → 400 mm, 58 bar width 455 → 410 mm, 61 bar width 436 → 400 mm, 61 bar width 455 → 410 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
