Some frames are chosen for a badge. This one is chosen for its threading. The LIBERIA frame carries French-standard bottom bracket threads at 35x100, a detail that decides which crank and bottom bracket assembly will actually go in before you ever consider paint. At 3325 g with a 55 cm seat tube and 57 cm top tube, the numbers put it in a workable territory for a period build without pretending it is something it is not.
The frame is steel and it is a used item. Oxidation is present and it is documented rather than glossed over — the photos form part of the description, so what you see on the tubes, lugs and dropouts is what you are assessing. Beyond that you should expect the usual cosmetic marks and traces of long storage: micro-scratches, small scuffs, patina that no amount of description replaces. Nothing here is being sold as new.
What the 35x100 Threading Means for Your Build
French bottom bracket threading at 35x100 mm is not interchangeable with BSC or Italian standards. If your parts bin is organised around BSA cups, this frame is not the one to force. If it is organised around French cups — or you enjoy the specificity of a French-threaded project — then the 35x100 shell is exactly why this frame is interesting. The fork thread is 25x100, and wheel diameter is 622 mm / 700C, both of which narrow your rim and fork choices in a predictable way.

The 55×57 cm geometry — measured as seat tube from the bottom bracket centre to the top of the tube, and top tube centre to centre — is stated here in the same terms as the frame was catalogued, so you can compare it directly against a bike you already ride rather than guess.
Where This Frame Sits in a Vintage Build
If you are assembling something in the touring tradition — a French touring bike rather than a pure racer — the 700C wheel standard and steel construction keep your options wide. Builders working on similar period frames often pair a project like this one with a set of period-correct rims, and if you are still choosing running gear, the MAVIC Monthlery PRO 700c tubular rims, 36/36H are a natural companion for a 700C French build. For a second reference point on French threading, our FOLLIS vintage steel frame, 53x53 cm, 123.4 mm spacing is worth comparing side by side.
Two things decide this frame. The thread standard, and your tolerance for a project with visible oxidation. Both are stated plainly above.
