Corrected values: bar width
XS bar width 410 → 380 mm, S bar width 410 → 380 mm, M bar width 430 → 400 mm, ML bar width 430 → 400 mm, L bar width 450 → 420 mm, XL bar width 450 → 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
