French threading: what this frame actually accepts
The two thread values are the first thing to check against your parts bin. The bottom bracket shell is threaded 35x100 "Français" — the French standard, distinct from BSC/BSA, so a compatible French-thread bottom bracket is required. The fork carries a 25x100 steerer thread. Neither value is interchangeable with Italian or BSC without adapters, and a restorer who already works in French threading will recognise the fit immediately.
