Handlebar racing AVA 380-21.8 mm vintage bike Eroica R354

Two dimensions define the fit

On a used drop handlebar, the numbers matter before anything else. This AVA bar measures 380 mm across the drops and 21.8 mm at the centre clamp zone. That combination is the first thing to check against your stem and your shoulder width. One millimetre off at the clamp and the assembly stops making sense.

A period-correct road bar

The AVA name places this handlebar in the classic French road lineage. The item is used. Photos are part of the description: inspect the finish and the clamp area closely, as they show the true surface condition. Minor cosmetic marks or storage wear may be present; anything structural would be stated outright.

What to verify before fitting

• Clamp diameter: 21.8 mm
• Overall width: 380 mm
• Bar type: racing drop, available as a used component

The absence of a model year means the bar should be treated as a period part rather than a dated collectable. The key is fitment. If you are building a wheel with a matching period feel, a Mavic tubular rim can sit under the same aesthetic, or you can compare this bar against the AVA 400-25 mm version if you need a slightly wider stance. For a full cockpit refresh, the Campagnolo 26.4 mm seatpost shows the same generation of European components.
