When I was out on a ride with a local group Thursday night I had a shifting problem. I could not shift into my large chain ring. I had to resort to reaching down and pulling on the cable that runs from the shifter to the derailieur.
Upon my return home I realized the cable was pretty loose and no doubt from me pulling on it. So I set out tightening it on my own and am happy to report I was able to fix it. During my subsequent rides it shifted flawlessly.
This was a simple fix. I would have normally taken the bike into the LBS for this kind of repair but after taking a bike maintenance class I was confident in my abilities to make this adjustment on my own. Yippee!
