Pictures! I'm not a wealthy man, so I used a cell phone. Not a great one, either.
Two questions!
1) Can a rear rack be attached to this kind of bike? The better half has appropriated it as her commuter (which feels wrong, but she's loving it). There's a mount point near the rear dropout, but best I can figure is I'd need a type that attaches to the bolt shown in the second to last picture, which otherwise doesn't seem to do anything.
2) What is that nub in image 4? It's this random nail-like thing on the right seatstay. Doesn't seem to do anything.
