I would be pissed having had mdeth1313 experience, I've had a bad experience with C-4 hubs, I know what it is, I know how a hassle it is, it sucks. Stop taking us customers for fools.
For me it wasn't all that terrible (at least at this point). I went into this well aware of the history of ZG, and I kept printed copies of everything involved. I think Ted is a brilliant engineer but he either needs to be an employee or hire someone to manage the sales/customer service side of things.
By comparison, I recently had one of the WW posters build a carbon cradle for my seatpost. As I had previous correspondence with him, had seen his reputation and had others who also placed orders verify his reliability, I had no issue having him build that part for me, even though he's not in the US. As it turned out, I ended up selling a stem to a friend of his and deducting the cost of the cradle from the stem and his friend paid him that part.
When it took a little over 5 weeks to arrive, the builder/seller was talking about how to resolve the problem when I didn't think there was one- we stayed in touch and it showed up. I was never worried and never had any doubts.
Funny, I also had an issue w/ C-4, but the shop I purchased the wheels from rebuilt the front wheel with a different hub and made things right. In this case, there's no one else to go to, unless you paid with a credit card.
My intention here is not to bash, only to share my experience. I doubt there will be any response to my post because what I posted is true (and I have a paper trail to back it up).
