Finally got to take it for a ride on the rail trail today...about 1.5 hours, not sure of the distance but probably at least 11-12 miles. I think the rear derailleur needs some adjusting b/c it was shifting when I didn't want it to at times (interestingly, worse on the road on the way to and from the trail). The local bike co-op has adult open shop one night a week, so I will probably drop in there and see if I can get some help figuring out how to fix that problem. I'm surprised (and kind of annoyed) that the place I got it from didn't check and adjust that before selling the bike. Other than that, it was a fun ride and I think I may end up enjoying the mountain bike more than the road bike...probably not surprising since I prefer trail running to road running and just generally enjoy doing things out in the woods.
