• Yo fam.

    So I need a 36 hole Rear hub that isnt a System X / Formula etc and was just looking down at OYB at the Primatos they have there... looking good and a good price too but what's this whole carrier mallarky?

    I am not down with it at all so... can anybody tell me: Do I have to use this carrier device or can I just wang on my cog from my current formula hub?

    Different thread pitch?
