Review on X1 75 2 125 LIYYOO Puncture Schrader Mountain by Ray Mcknight

I bought this with an open box discount and can't imagine how dissatisfied I would be if I paid full price. My first impression was that I got a great deal and I was just glad there was no obvious damage. When I started checking for air leaks, I knew I was going to have trouble installing the hose. A Schraeder valve might technically be within the quality control limits of the 8mm and 32mm specs, but when they do, they override the metric system. I had to push, twist and slide the pump nozzle head linkage valve onto the stem with all the force I could to the point where I was certain I had damaged my pump. No wonder, then, that the stem needed lube before it pushed through the hole in my rim so I could move on to the next problem. The "32mm" stem isn't even long enough for a brass ring to fully clear my rim. . I must admit that I have aero alloy rims and my wheel depth is 35mm, but have never had any other tube with such problems. I also put a tire and tube on a stock rim and encountered the same problem, albeit to a lesser degree. Final Verdict: Custom manufacturing should be the explanation as there is no such thing as a 10mm valve or 26mm stem made or used by any bike manufacturer.
