Da notare che il logo accanto al pulsante di accoppiamento delle cuffie è uguale a quello presente nella Xbox e nei controller. I was able to fix my bike and assemble it with the use of solely this toolkit as my bike also had Shrader valves and the nuts and bolts were of the size that this toolkit was able to fix it with. 5 size fits JUST right. very uncomfortable so I had to return them! I would order up a size they were short and tight. The very thin bottoms wore out in the middle of the foot pad, all the way through, and the seam is coming out on the sides. Bin zufrieden. Phone was ok, thankfully. but these should fit fine for people who generally wear mediums. (I wouldnt recommend others doing this, however, I think I was very lucky - particularly as I had only had them less than a week!
