Description

Lightweight French Metallurgy for Vintage Builds

This authentic ROBUST frame, constructed from high-grade VITUS 971 double-butted steel tubing, offers an exceptional strength-to-weight ratio for collectors and workshop projects. Weighing in at a highly competitive 2625g (including fork), this chassis is a superb foundation for a responsive vintage road build. The tubing is celebrated for its dampening characteristics and classic ride quality.

Mechanical Specifications & Alignment

Engineered for 700C wheelsets, this frameset features standard vintage spacing measuring 100.6mm at the front and 121.6mm at the rear dropouts, accepting standard vintage friction hubs. Please note that the detailed product photos form an integral part of this description, illustrating the exact paint condition, decals, and lug details. Minor cosmetic wear and surface oxidation consistent with age are present, but the structural integrity and tube alignment remain sound.

If you are looking for alternative tubing options, you might also be interested in our Vitus 172 vintage frameset, or for a slightly larger setup, check the Louis Ocana 57.5cm steel frameset.
