I got my son a haro junior sx group one for Christmas for racing this summer, well its a little to big for him so I am going to keep it for myself and get hima mini. I am going to race too! My question is it has 1 3/8 wheels on it, umm I think they are Alex rims. IT seems that someone mentioned that there wasa weight limit of 95lbs on this! I seem to think there is no such thing. Can seomone help me out with this. I am 5ft 119 and I think this is a perfect fit bike for me!
