So I finally got my nashbar hounder setup and thanks to all the people who gave me advice. I thought it provided a smooth ride. But there were several things that had bothered me. First, my wrists felt like they were being strained. I don't know if this is because it's my first time riding a road bike in such a long time or it could be something like my saddle height maybe? Second, I felt my lower back got really tired after riding awhile, and this might again be related to saddle height? The brakes were obviously weak like everyone mentioned, but it will work for now. And I noticed that putting either one of my feet down on the crank will make the bike drift in that general direction (i have ridden mountain bikes before and have no felt this effect until now). And I keep wobbling at times even when I challenge myself to either make a corner or avoid certain objects. Is this normal and will I get use to it with time? I also ate it once already, so that was a good experience. haha. The seat was the worst...!!! Felt like sitting on a shark rock.

Let me know how I can correct some of these problems. Thanks!!
