I just bought a used Felt Q620 to try my hand a trail riding before I invest serious money in a nicer bike. If it turns out that I enjoy it, and am physically strong enough to participate, then I will look into something better.
This bike is in good shape overall, everything works, chain and cables just replaced and a fresh tune up. It rides and shifts well, the Dart 1 obviously ain't much, but its working probably as good as it ever did. The mechanical discs seem to work OK. High gear chain ring is worn and probably will get replaced. Cassette looks almost new. Frame is in good shape with no dents or dings and only a few scratches.

Hope to get out on the local trail park next week for the first time ever off road on a bike.
