Internal gear hub tear-down

Winter bike #2, the one with the Sachs Spectro hub, made a cracking sound one night and then was reduced to about 3 gears. So I had to open it up to find out what went wrong. Fortunately RGB has overhauled these hubs before, and so we met up at the re-Cycles shop.

I only thought of videoing once he started showing me how the gearing-changing mechanism worked, and it's now on YouTube.
