This cassette lockring uses the modern 27 x 1 thread, for 1999+ Record/Chorus hubs and all Campagnolo hubs from 2000+. While it's technically from the 10 speed era, it will work with 11/12 speed too.
For 12T and bigger start cogs. Will not work with 11T start cog cassettes.
Beautifully constructed, made in Italy, weight weenie lockring for discerning cyclists who mind every last detail.
