I guess I shoulda checked the QR. I'm not used to using an LBS, so I didn't even think of it. I'm sore, but since I haven't gone down since I was a teenager, I can tell that I am a little apprehensive about getting back on the bike and riding my normal route. Perhaps this will get better with a few short rides? In the back of my mind I am thinking "maybe the QR was tight and the frame just can't hold the wheel". It's a new frame so I really have no past experience with it to rely on.
