i do mostly tight single track riding with alot of steep, rough up and down hill with a few small jumps and drops. i'm looking to get a new bike soon, and favorite lbs carries stumpjumpers at a good price. but i dont really ever see anyone in the forums recommending or even talking about the stumpjumper in general. are there problems that no one in the reviews are telling? is it crap for AM/XC? HELP!
