Everything. Just a poor handling, sloppy bike. Heavy, flexy, FRIGHTENING on descents with this shimmy (and this is when I was young and dumb enough to really descend). I really disliked that bike...to the point where I even used a Cannondale instead on a few rides. I saved up for months to get it...it was what I could afford, but it sure didn't handle or ride like my wealthier friend's (and better sponsored friend's) bikes.
