It pays to be attentive to your bike and your body. I just bought my Trek 7.5 WSD last week. Figured I wouldn't have to adjust anything until about 100 miles or so. Well, hey, I'm a newbie and naive! So a few days ago, my wrists started hurting a little, my mirror was out of whack and my front gear didn't shift quite so smoothly. I said something to my husband yesterday. He rode the bike and agreed something was wrong with the shifting. He stood in front of the bike and looked at it, then asked me when I rotated my handlebars backward! I hadn't, intentionally that is! The handlebar must have moved when I heaved myself onto the seat and I didn't notice. So we adjusted the handlebar to its correct position and marked it with a Sharpie. I had a great ride today, the mirror was good, the shifting was good and my wrists didn't hurt.
