I am thinking about selling mt specialized stumpjumper fsr xc and getting a single speed mt bike. I have no experience with a single speed but would like to get into it. Most of the terrain is flat where i ride but very technical with rocks and roots where i ride in maine. I am looking at the Bianchi SASS cromoly frame and fork. Let me know what you think. How many of you do some serious technical mt biking on a single speed.
