Nitto UI-76 Stem
The UI-76 is Nitto's threadless stem for classic and modern builds — a 25.4mm bar clamp with a 73° angle that puts you in a balanced, slightly upright position without sacrificing control. Available in polished silver or deep black, in seven lengths from 60 to 120mm.
"UI" stands for Ultimate Ideal. The UI-76 earns it. Engraved Nitto logo on the drive side, made in Japan.

Choosing Your Length
Stem length affects reach and handling. Shorter stems (60–80mm) suit more upright positions and tighter handling; longer stems (100–120mm) extend reach for a more stretched, performance-oriented fit. If you're unsure, 80–90mm is a good starting point for most road and commute builds.
Why Nitto
Nitto has been handcrafting bicycle components in Osaka, Japan since 1923. The UI range is their flagship threadless line — built to the same standard as everything else they make.
