Nitto B2500AA Handlebar

The Nitto B2500AA requires a stem with a 25.4 mm clamp diameter. Please verify your stem size before purchasing, as this is the standard size for many vintage and city bike setups but will not fit modern 31.8 mm oversized stems.

This bar is designed primarily for urban utility and short-to-medium commutes. Because it features a perfectly straight geometry with zero sweep, it provides a very direct, upright feel that may not offer the ergonomic wrist support required for long-distance touring.

Yes, the aluminum construction allows you to trim the width if you prefer a narrower profile for navigating tight city traffic. We recommend using a proper pipe cutter or a hacksaw with a guide to ensure a clean, straight edge.

The anodized finish is quite durable and resistant to corrosion, making it well-suited for daily city use. Simply wipe it down with a damp cloth occasionally to remove road grime and keep it looking clean.

The grip area diameter is 22.2 mm, which is the industry standard for flat bars. This means you can use almost any standard mountain bike or city bike grip, including rubber slip-ons, lock-ons, or even track-style tape.
