Nitto UI-85 Stem
The Nitto UI-85 is a refined threadless stem built for riders who demand precision, durability, and understated Japanese craftsmanship. Machined in Japan from high-quality aluminium alloy, the UI-85 carries Nitto's hallmark attention to detail — clean lines, a discreet engraved logo, and a finish that holds up beautifully over years of riding.
Designed around the 25.4 mm handlebar standard, the UI-85 suits a wide range of classic and contemporary builds. Its 85° angle (±5° reversible) gives you meaningful positional flexibility without compromise, whether you're setting up a relaxed commuter or a more purposeful road bike.
Available in gloss black or polished silver, in lengths from 60 mm to 120 mm — find the fit that works for your geometry and your aesthetic.
