NOS Vintage Phil Wood Knurled Track Lockring: For 3-Piece Hubs - Left Thread 1.32" x 24 TPI
These are the ridged lock rings that came with early Phil Wood 3 piece pista hubs from the 1970's and early 1980's. The left hand threaded ring's diameter is 1.32" x 24 TPI, which fits Phil Wood and Campagnolo track hubs. Stupid rare.
New old stock, never installed.
