Help!
I just bought a wheelset with an Origin8 flip-flop hub in the rear. I need to buy a lockring and cog, but I'm not sure how to buy them as I don't know if they're all a universal size or not.

Here's the one I would like to buy:

Here's a similar one, but the hole looks waaaay bigger;

Please ignore my incompetence and help if you are willing! I'm still learning...I'm a total bike noob :(

Furthermore, are lockrings universal too?

No need to apologize. :)

Here you go:

Some lockring are Italian threaded, Miche, Phil Wood and Campagnolo lockrings are all Italian threaded and they will not work with your Origin8 hub.

ISO/English cogs are 1.37" x 24TPI.

Italian lockrings are 1.32" x 24 TPI
ISO/English lockrings are 1.29" x 24 TPI.
