The 400 mm width and 25.8 mm clamp measurement define the fitment window for this racing handlebar. These two figures matter first: they tell you immediately whether it will sit correctly in a stem of the same era and whether the hand position matches the frame's intended geometry.
This is a second-hand racing handlebar. Width across the drops is 400 mm. The central clamping section measures 25.8 mm — a size that corresponds to a specific generation of road stems. Always verify the stem's internal diameter against this before planning a build.
The photos document the surface state of this handlebar as it sits in stock. They are an integral reference for assessing wear, finish, and any marks typical of a previously fitted component.
For a period-correct cockpit setup, compare this bar with the AVA 400-25 mm racing handlebar. If you are working on a complete rolling chassis, the Campagnolo Record 26.4 mm seatpost may also be relevant to the same vintage build.
The clamp section has a diameter of 25.8 mm. This dimension must match the internal diameter of the stem used for the build.
The handlebar measures 400 mm across the width. This is the key figure for evaluating hand position and period-correct fit.
This is a used vintage racing handlebar. The photos form part of the description and show the current condition of the surface.
A 25.8 mm clamp diameter is associated with a specific generation of road stems from the same era. The stem's internal diameter must be verified to confirm compatibility.
