Seems like you're doing quite a bit of venting for what is a cheap fixed gear frame. I in fact love my Mark V Pro, but the first thing I changed was the front fork, not because there was any problem with it but just because, I prefer my FBM Sword fork instead. But unfortunately, you can just be unlucky and get something defective and it's just your bad luck. It happens to all of us. I would email them, they still might be willing to help you out and replace the fork. They have a new Mark V Pro fork that has a 30mm rake and uses better tubing than the other stock forks.
