A slight drawback would have to be corrected then there from me 5 stars. By items (from disassemble) the tire wobbles whenever you do not keep him in the exact scale ... and a tire of wobbles revolves not good. You have to practice a lot to you so reasonably cope. For beginners I think would not be recommended.
Otherwise: I do not get bruises, the weight of the tire is very pleasant and if he does not wobbles times (ie when I take the good in the hand) runs the also perfectly his Hüftrunden.
