First off, send the hub back to Sovos and get a refund. There is no excuse for striping threads after one ride. Then, go buy yourself a decent hub, like a Surly, Suzue Promax, or Kogswell/Van Dessel (same hub, but only if you have 135mm rear end). Finally, buy a Dura Ace or EAI cog and a DA lockring, and install.
