My builder is Zealot Bikes out of Corona, CA. They're a small operation and I can't speak to the volume of frames he's built but after extensive conversation (and several rides) with Jeremiah I felt sufficiently comfortable with everything to place an order.

I've put over 1000 miles on the bike (since July 2013) they built for me and I have no complaints. I have also been impressed with the amount of post-delivery followup contact they've initiated. I can tell they're genuinely interested in my satisfaction with the bike and that means a lot to me as a customer.
