I think I totally understand the apprehension with fixing stuff. I remember a few years ago, I was too afraid to even adjust my shifters because I was afraid to mess something up. Plus all those warning stickers about how things need to be installed by professionals or else you will die.

But after a while, I realized that you will not die if you mess something up. So I started to work on maintenance. I took a couple of classes. And I now rarely go to the bike shop to get things done. Of course, I still go there because my fave bike shop has the coolest people in the world. So helpful.

And I do agree with people asking about questions that can could have been answered if they actually took the time to help themselves. My fave site is : http://lmgtfy.com/
