Sugino NJS stepped lockring

NJS stamped track lockring made of hardened steel w/ black phosphate finish.

This version features 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 if you so desire.

Not compatible with Campagnolo, Miche, Phil Wood, Mack or Mavic hubs.
