The $35 Hub
This hub is offered by several companies at various price points. It is a essentially a Formula BX-2210 BMX Cassette Hub with 135mm spacing and an upgrade to cartridge bearings. It can also be found as a Novatec (Joy) D256SBT. Other companies branding it under their own name are Woodman, Planet-X (On-One), IRO, and Bontrager. Many others may exist, but the cheapest one I was able to find was the Nashbar NF-SSHR.
The Nashbar hub includes a sprocket which some of the other companies neglect to include.

Gearing The Cassette
The cassette lockring is a standard 1.37x24T right hand thread lockring. Same as old school bottom brackets. I replaced the cheapo one with a nice old Suntour version that I had in stock.
