Today I took my trek 400 for a little whip around town, about 7 miles total. Learned a little about it, shes a bit squirrelly, and sometimes shifting from the 3rd ring to the 4th, nothing happens. I have to go up two then back down one. It could probably be fixed in 5 min with some adjustment to the rear derailleur but I have no idea what I'm doing when it comes to geared bikes. So I'll just leave it how it is until something breaks.
