All-City cro-mo lockring
Machined from hardened chromoly steel, 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.
🔧 This will not fit Campagnolo, Miche, Mavic or Phil Wood hubs.
