Nitto B123AA Handlebar

While the B123AA is designed specifically for track racing and aggressive velodrome positioning, many fixed-gear riders use it on the street for its classic aesthetic and stiffness. Just keep in mind that the deep drop and reach are optimized for track geometry, which may feel quite aggressive for long-distance road riding.

No, the NJS stamp is only applicable to the silver version of the B123AA. The black version is identical in construction and geometry but does not carry the official NJS certification for professional keirin racing.

The Nitto B123AA requires a stem with a 25.4 mm clamp diameter. Ensure your stem matches this size, as it is a standard track sizing but smaller than the 31.8 mm diameter common on many modern road bikes.

With a 175 mm drop and 108 mm reach, these bars offer a very deep, aggressive position. This geometry is intended to help you get low and aerodynamic, which is ideal for sprinting and track racing, but it will be significantly more demanding on your back and neck than a standard road handlebar.

Yes, these bars are crafted from heat-treated aluminum, which provides excellent structural integrity and stiffness. They are built to withstand the high-torque demands of velodrome racing, making them more than durable enough for regular, everyday riding.
