Machined from hardened cro-mo steel and chrome plated, this lockring has a stepped design that prevents the chain from making unwanted contact with the lockring when using a 12t cog.
Of course, you can use this lockring with other size cogs too.
• standard 1.29"x24 tpi left-hand threads
• chrome-plated finish
This will not fit Campagnolo, Miche, Mavic or Phil Wood hubs!
