Handlebar racing 380-25.2 mm vintage bike Eroica R312

The racing handlebar in this listing is defined by two values that matter first: 380 mm of overall width and a 25.2 mm clamp diameter. Those two figures determine how the bar sits in your existing stem and how the rider's hands fall on the drops. This is a used handlebar, sold as such, and the photos form the core of the condition report — inspect them for surface wear and any marks from previous mounting.

What these measurements mean for your build

On vintage road machines, centre clamp diameters were not universal. A 25.2 mm bar requires a stem with a matching internal diameter. The 380 mm width is a classic racing width for taller or broader riders on period steel frames, giving a firm position on the ramps and a confident reach into the drops. When you inspect the images, look closely at the clamping zone and the ends of the bar: that is where prior installation leaves its clearest traces.

If you need a different width for a smaller frame, compare the 390-22 mm racing bar before deciding.

A note on purchasing used handlebars

Used aluminium bars carry the memory of every bike they have been fitted to. Minor cosmetic marks and light scratching from storage are normal. What matters is the integrity of the clamp area and the absence of deep scoring, bending, or cracks. The images for this listing show the actual bar you will receive; treat them as the full condition documentation.
