Sugino NJS lockring - stepped
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.
• made in Japan
• standard 1.29"x24 tpi left-hand threads
This will not fit Campagnolo, Miche, Mavic or Phil Wood hubs so don't bother trying!
