The Good: I rode one of Doc's first prototypes, and within minutes I knew this was the frame I was going to own. I tried to give him cash right that moment, but he wanted to wait until the bikes were actually done. Love the clean lines, tight geometry, and smooth ride. Just awesome.
The Bad: I originally had the regular frame, and my size 11's didn't clear the tire on barspins. Once I got the XL frame, that was fixed. If you have size 11's, and like to spin the bars, go with the XL frame.
Someone needs to give Doc a CNC machine so he can include chain tensioners with the frame. Those tight little dropouts make finding the perfect tensioner a bit tough. Doc has some good recommendations for now, but that was the hardest part of my assembly of the bike.
The frame is super dialed. If you get a chance to ride one of these, consider the fact, that once you have ridden it, you won't want any other frame.
