BF BELLERI Quill Stem 21.9-25-70mm Vintage Touring Bike Eroica PO26

The BF Belleri quill stem sits in that narrow band of cockpit parts that makes or breaks a period-correct build. French aluminium, a 70 mm reach, and the 21.9 / 25 mm fitment that resurfaces on a specific generation of European touring frames. For anyone assembling an Eroica-legal machine, that combination is the starting point, not an afterthought.

Why this Belleri stem suits a vintage touring cockpit

Three numbers decide whether a quill stem works on an old touring frame: the outer diameter that enters the steerer, the inner diameter that clamps the bar, and the reach that positions the rider's hands. Here they are 21.9 mm, 25 mm and 70 mm — a compact, upright-biased reach that reads as touring rather than criterium racing.

Parts in this family turn up in the hands of restorers chasing the stance of a French randonneuse — a touring bike built for long days, not for the start line. If you are threading the same cables and levers through a matching build, the Mafac brake lever for 1940s–50s Peugeot touring bikes belongs to the same cockpit conversation. A closer sibling in diameter and intent is the Belri Course stem 21.9-25 90 mm — same fitment, longer reach. And for the broader search through period-correct steering components, the spare parts hub is the practical entry point.

Condition and inspection notes

No oxidation is declared on this stem, and it is presented as a used vintage part. Cosmetic marks and traces of wear consistent with long storage — micro-scratches on the surface — are to be expected on the original finish.
