NITTO Grand Randonneur B132AAF Handlebars | 25.4mm
The B132AAF Grand Randonneur is Nitto's definitive touring handlebar — shallow flared drops, upswept flats, and a geometry that gives you more hand positions than almost anything else on the market. Built for long days in the saddle on rough roads, it's the bar of choice for randonneuring, audax, and loaded touring.
The flare angle opens the drops out to 74°, giving a natural wrist position on descents and rough terrain. The 9° upsweep on the flats keeps your hands comfortable on the hoods for hours. This is a considered bar for considered riding.

Choosing Your Width
Handlebar width is typically matched to shoulder width. Most riders fit 400–420mm. If you're running wider tyres or bags and want more control, 450mm gives extra leverage. Measure between the centre of your shoulder joints as a starting point.
Compatibility
The 25.4mm stem clamp is a traditional diameter — compatible with Nitto's own quill stems including the Technomic and UI-12 range. The 23.8mm brake lever clamp suits most road levers.
Why Nitto
Nitto has been handcrafting bicycle components in Osaka, Japan since 1923. The Grand Randonneur is one of their most iconic designs — unchanged because it doesn't need to be.
