hey i am new to bmx racing and i want a new bike, i was thinking about the haro sx group 1 xl, do you know if this is a good bike? I would like future upgradeability. I was also thinking about the fmf complete. it is light 1.5 lbs lighter frame than the sx. any thoughts would be great. I was also thinking about buying a used brew racing frame, but those are alot of money...
