I just got a new wheelset with an Origin8 flip-flop hub in the rear, does anybody know what diameter cog and lockring I need to buy? I'm not very good at measuring :\

As far as I know they are are the same. But just know, cog/lockring is one place you really don't want to cheap out on. I hear good enough things about 1/8th" stuff and they are doing a thing where if you like them on facebook you get a coupon. So I would do that if I were you, just make sure you are getting a cog in a reasonable size appropriate for how you will be riding. Look up stuff about gear inches to figure that out. Most people are fine somewhere between 70-76 gear inches. Much more than that and it starts being a pretty tough but doable gear.

You're right, it was not worth starting a thread.

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.

I feel like a jerk, but this is a properly titled thread. Do a bit of research and you'll be fine. Chances are that your cog and lockring will be the same as 95+% of them out there.
