Hah! Just broke my Park CT3 chain tool yesterday. Pin snapped right off because I didn't make certain the attachment was fully screwed in. Another $10 mistake.

And like you, I just wrapped my handlebars for the first time after watching a YouTube video and it was CAKE! I was shocked at how simple it was to get something that looked really good. I really feel sorry for people that have their LBS charge $10 for that! Now I want to change colors every week.

Yeah, derailuer adjustments suck. I use the book by Zinn and a couple of videos I found online and I can get it relatively close. The front is a pain in the neck for me.

The bottom line is that I don't enjoy bike maintenance. In fact, I hate it. There are others that love it and I bet they're damn good at it.

I basically can change out cables, adjust the derailuers, replace the chain, change the tires and brake pads and wrap the handlebars. Anything else means the LBS. And money. Ugh.
