Nitto B123AA Handlebar

NJS certification stands for Nihon Jitensha Shinkokai, the governing body for professional keirin racing in Japan. It signifies that this handlebar meets the strict safety and quality standards required for professional track competition.

While technically designed for the velodrome, some riders use these for fixed-gear street riding due to their durability. However, the deep-drop geometry is quite aggressive and may be uncomfortable for long-distance road riding compared to standard road bars.

Most likely not. The Nitto B123AA requires a 25.4 mm clamp diameter, which is a standard size for track stems but smaller than the 31.8 mm clamp diameter found on almost all modern road bikes. You will need to verify your stem's clamp size before purchasing.

The heat-treated aluminum alloy provides a significant weight reduction compared to traditional steel bars while maintaining the stiffness required for high-wattage track sprints. It offers a more responsive feel without the heavy weight penalty of steel.

This handlebar features a 170 mm drop and a 108 mm reach. This creates a classic, deep profile that allows for a very low, aerodynamic position essential for track racing.
