Not much to report, as I haven't been in the saddle much since mid-November when I had a bad off and broke two ribs and tore a shoulder muscle. The latter isn't right yet, but isn't bad enough to stop me riding into work this coming week.
I managed to find a replacement, 7-speed, Nexus-hubbed wheel on eBay and it was a straight swap - except for needing to remove a couple of links from the chain because the sprocket was smaller. That takes away the decision about whether or not to raise the gearing! I swapped both wheels simply because the Continental Contact tyres on the originals are impossible to remove. I now have the Marathon Winter studded tyres fitted. Much wider, heavier and slower, but much, much safer in colder, icy conditions.
A short ride today on a very boggy canal towpath saw the bike perform smoothly. The Nexus gear shifter works well with the new wheel, thankfully. A combination of the higher gearing, wider tyres and my lack of fitness saw me in lower gears than usual, but I can live with that. I'm hoping the battery will see me to work and back.
