Niner ORE 9 RDO
2025 · 700c wheels · 6 sizes
Carbon drop-bar gravel bike from Niner, the 'Off Road Explorer', with a suspension-corrected front end that accepts up to a 40 mm suspension fork. Numbers are for the stock rigid carbon RDO fork (435 mm axle to crown, 50 mm rake). Chainstay is the actual length of 435 mm; Niner also lists a horizontal chainstay of 430 mm. Clearance for 700x50c or 650bx2.0 tyres. Niner's imperial geometry table contains conversion errors (for example the 56 cm reach), so the metric figures are used.
