Was tinkering with the gears a bit last night. For shifting the rear derailleur, it seems like quite the sensitive battle. I assume there are five positions with the right gear lever, that would correspond to the five rear gears? Not sure, but having it at the half-way mark (about a 45 degree angle) resulted in 4th gear. Haha.

Thank you for the links, 1nceptor.

And all-in-one kits of tools that I need that might be a good buy?
