hi.. i wanted to ask someone elses opinion..i am from u.s. and bought rotobox carbon wheels from brocks in u.s. been having issues with rear rim hub having side to side play which seems like is coming from hub bearing..i sent wheel in to brocks first time and they said it was a spacing issue with hub itsself...they sent new wheel and hub and after 2 rides i have same issue..its like 1/8inch play...rim has ceramic bearings installed and i called them back and now they say its a bearing issue??? you guys had any issues like that?? its on a kawasaki zx14....thanks,steve
