The single mount is for a brake adapter (disc.)
it came with a little adapter that will make it a mount for a disc.

The bike comes with chain tugs, but yes, the bottom part of the dropout is a bit thin. I bent mine...I do blame myself mostly though because I landed on it vertically when riding trials (failed sidehop...).

Wow, you are a persistent jerk. What does it matter to you? Do you bike only for your image? If people want to ride a certain bike, then they are free to do as they please, and I don't see why it would affect you. If you have any serious arguments as to why you dislike this bike, then go ahead and state them but "this bike looks gay" is such an immature statement that means for sure that no one will take you seriously.
