Good to know: Configurable build

Corrected values: bar width
M bar width 480 → 420 mm, XXS bar width 420 → 380 mm, XS bar width 420 → 380 mm, S bar width 420 → 380 mm, L bar width 480 → 420 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
