Well I just finished my first bicycle maintenance job. I wanted to add toe clips to my hybrid and my current pedals weren't designed for them, so I bought a set from Performance, and a pedal wrench off ebay, and I jsut finished. Now I have a new set of pedals with clips. It was a lot easier than I thought. I figured I'd have to really work and get my wrench to "break" the pedal but it unscrewed with very little pressure.
