I have to say that "fear of wrenching" has to be one of the funniest titles for a post that I've seen.

Bravo with learning to tinker with your bike. It's commendable to say the least.

For the moment I'm taking a different approach.

I learned to strip a car down to a pile of nuts and bolts and put it back together again. Once I learned this, I decided to let someone else do it. I could afford it and wanted to spend my time elsewhere.

Now that I have a bike, I am totally not interested in working on it. I take this into account about when and where I bike so that I'm always within reach of a bus or a bike shop. The trade-off is worth it to me. There is too much else I want to be doing and there are only so many hours in the day. Bike mechanics doesn't make the list.

For those who work on their bikes...much applause.
For those who don't....much applause.
