The only thing i've heard about being bad on them is their freewheel's,you could buy a tensile one from tartybikes.Although i am sure if you are a beginner the standard one should be fine for a while,you might want to get new bars and stem a while after having it. I don't think standard onza bars feel right for trials feel too narrow,if you need anymore help add me to msn (my address is in my profile thingy) zoo baby!
