Odd BB threading?

[oliver1850]

I was sizing a bunch of loose cups and lockrings and found 4 lockrings that are smaller than French (35 x 1). I didn't find any cups that matched. It's kind of hard to measure the major diameter but they appear to be about 33 mm. All four are LH threaded. What are they for?

If it isn't here I don't know what to say:

Maybe not BB lockrings? Could be track lockrings (~33mm-ish)?

Would be lefthand threaded and a bit smaller than the 35mm-ish of a BB lockring.

I was thinking the samething.

But the trak lockrings are way smaller than any cup lockring tho.

Track lockrings come in 1.32" x 24t and 1.29" x 24t. They are probably track hub lockrings.

Aside from track lockrings, my old Sutherlands manual (2nd. ed.) says there is a Raleigh thread of 1 3/8" x 26 TPI with right handed threads on the adjustable side and left on the fixed.

Yes, they are track lockrings. I seldom use one and it didn't even cross my mind. Into the SS box they go, unless someone needs one.
