Retrogression cro-mo track lockring

CNC machined from hardened chromoly steel, our lockrings have a smooth black oxide coating and 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.
