Hey to the BMX world--- I am building up a fixed folder. (crazy but I have my reasons!) Since folders generally have 20" wheels, I am thinking a cheap solution could be to use old BMX wheels. Are there any BMX hubs out there which accomidate a track cog and lock ring? Used BMX stuff is a lot cheaper than building new from scratch. There does exsist flip-flop BMX hubs but I don't know about the lock-ring-thing, which holds the fixed cog in place. ( a freewheel does not need a lock-ring) BMX is just something I know very little about.
Thanks for any insight on this mucho apreciated!
