I grossly underestimated the amount I am riding the
pirate bike. I had guessed around 45 km/week. But I reset the computer yesterday at 120 km after 7.5 days.
Mind you, this was a week with almost no rain, so I was able to use it every day. Just lots of short trips, average 1-way length of maybe 3 km, max of about 6 km.
There are still a couple of stiff links in the chain that skip if I go top gear (big front ring, small back). It's not a lubricant issue - the chain is well lubed, but every time I work the stiff links loose, they seem to tighten up again.
