What can I say that hasn't already been stated about this high-quality lockring? It's nicely machined, the threads are perfect, and it works like a charm to keep my cogs from spinning off. Cheers!

Great design and a perfect complement to Velobike’s cogs and rings.

feels great, really nice and strong. excellent and well made product and would definitely recommend to anyone looking for a reliable lockring :)

I have a Yobi 12t cog, and I’ve been looking for a lock ring to work with it, and it’s fits perfectly. Works well with 12t cogs that do not have a lock and grove set up.
