I had oiled the chain a little last week when it started making some noise, but apparently it needs more oil than I gave it. I applied the oil after changing the wheel to reduce mess. The real reason for taking this picture was to show the bolt and nut to the right of the sproket. There is one of these on both sides of the hub.
Tada, no wheel in the frame. Note that I left the Nexus 8 gear cable connected, since there was no need to remove it.
Schwalbe Marathon Plus tyres which claim to be the ultimate in thorn-proofing. They are cited as being "quite heavy and awkward to fit". I don't think they are particularly heavy or awkward to fit -- again, I didn't even need tyre levers to get the new tyre back on. And compared to the weight of the rear wheel, the tyre is quite, quite insignificant. And like all Good Sensible Tyres they have a 3M reflective strip for night visibility way better than any wheel reflector provides, and without the weight imbalance that reflectors provide:
And, ta-da, all back in. Then it is time to refasten the chain case:
The whole process took me about an hour, but if I had to do it again, it would take perhaps half that.
