I'm pretty sure it takes an Italian lockring.
I used to commute with one of these until the flanges blew up. They're beautiful but maybe a little delicate for the road.

I'm thinking a BS threaded ring would thread on but with some slop if it were French; on the contrary a French ring will thread on to a BS set of threads?
I'm also think? it would only be the Lockring threading that would be French threaded?

I believe the lockring on a track hub is reverse threaded. I doubt its French threaded.

hub threading sizes
French threads 34.7mm x 1mm (1.366" x 25.4 TPI)
English threads 34.8mm x 1.058 (1.370" x 24 TPI)
Italian threads 35mm x 24 TPI (1.378" x 1.058mm)
ISO threads 34.92mm x 1.058 (1.375" x 24 TPI
French lockring size
It looks like French thread lock rings are 33mm x 1.0mm (1.299" x 0.039"). I guess that they have Left Hand threads.
thanks chas
