That looks strange with the shifter cable pointing back like that. Mine goes forward under the chain stay. You notice these things when you got em. If you have shifting problems, put it in forth gear and make sure the yellow lines match up (I can see it in the 4th picture, a little window on top of the rear hub by the chain). Mine was built in winter and by summer the cables had stretched a little and had to readjust it a few times. Have you gotten used to twisting up to shift down yet? It took me about a month.
Looks like a Kenda tire tread I had on my old bike. The all black wheels look nice when you have the disk brakes. The silver circles I have kind of ruin the effect on mine. I haven't put water bottles on mine either. Without all the mass of caliper brakes and stuff, I like the uncluttered look.
Are you happy with the gear inch range? I took me a few tries to get was best for me. I currently have 48 tooth crank in front and the 21 tooth cog in the back.
Wait! Three leaves... non serated edges... That's poison ivy!
Be careful. Photo #3, to the right of the "S" on the head tube. Like I said earlier, you notice these things when you got em. Dam bush hoggers. I should have know better when I passed that road crew.
Enjoy your bike.
