No, I have not heard anything back from them. I really don't expect to until Monday due to the Thanksgiving holiday. I'll definitely post when I hear back. If I had know that whoever is building these things in Tiawan was basically permanently installing the cogs I never would have ordered the bike since I knew the 16t cog was going to be too much for my terrain/legs.

Like unogear said I'll just switch out the chainring and save my pennies for a new wheelset in the future if the folks I ordered the bike from won't make good. Just kind of annoying....
