Handlebar racing 390-25.5 mm vintage bike Eroica R179

The 390 mm Width and 25.5 mm Clamp

This is a used racing handlebar measuring 390 mm across. The clamp area is 25.5 mm. That pairing — 390 mm of width and a 25.5 mm stem clamp — is the practical detail that decides whether this bar fits your build. It is a straight data point, not a guess.

No brand marking is listed in the product data. What remains is the part itself: a drop bar from the era of steel frames and toe-clip pedals. The code R179 identifies this specific item in our stock, not a model number.

The photographs are part of the description. They show the exact bar you will receive, including any wear from use. Look at them closely before deciding.

Used, Not New: What That Means

This bar is a used component. It will carry the normal traces of a part that has been mounted and ridden — small scratches, light marks on the clamping area, maybe a dulling of the finish in the grip zones. Nothing major is reported for this bar. If a serious flaw existed — rust, a bend, a crack — it would be stated here in the description. It is not. So you are looking at a usable bar with cosmetic wear, the kind any old workshop bin would hold.

Measure your stem. A 25.5 mm clamp is a very specific size. Check that before buying.

For a full period-correct front end, you might also look at our steel fork with a 162 mm steerer or the 390-22 mm racing handlebar if your stem takes the narrower clamp.
