Rear Dropout detail.

Note the machined plug at the bottom of the seat strut. Most of us (Including many manufacturers) just mash the ends of the tubes flat. Given that he does details like these and builds bike faster than almost* anyone else in the club. I'm gonna guess he doesn't spend a lot of time in fromt of the TV.

The frame also has a kind of neat (but temporary?) finish that looks rather like machine turning and was caused by using a random orbital sander to remove anodized areas and prepare the pieces for welding. He had to use it on some areas of the frame and decided to just go ahead and do the whole thing that way.

* Except for Osell, and Dave "Weld first, measure later" Krafft.
