I rode my "Mono"goose 29er to work today, since our department is taking the afternoon off for a group mountain biking trip to Kettle Moraine state forest. On the way to the grocery store to pick up some post-ride snackies, I went off the road to hit a short, super-steep grass hill near the bus line's west transfer point. Halfway up, disaster was lying in wait - a broken chain! A lost plate! No extra links in my bag! On my geared bike, I could just shorten the chain a link and keep riding, but that kind of trailside fix doesn't work on a singlespeed. So I started walking. And then I scooted for a while, but that looked stupid so I stopped.
When I got to work, I realized that the easy-to-fix chain wasn't the only problem - I had also lost the roller for my chain tensioner! I called Rennen to get a replacement, called Missy to have her bring my other mountain bike, and pouted. Then I decided to grab fortune by the nads and jerry-rig a roller using a brake bolt sleeve, some washers, and a rear derailleur pulley. And it worked! Joy of joys, it worked!
