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.
Not compatible with Campagnolo, Miche, Phil Wood, Mack or Mavic hubs.
• standard 1.29"x24 tpi English threading
