if a bike shop cant remove and replace an ordinary wheel properly?how low tech are these compared to modern wheels and brake assemblies,im guessing they had an apprentice on it.is the rear sprocket cush drive inserted properly aswell?ide go back and point out the mistake,is that tyre still safe now?i had an inspection fail on my car because the guy said it had no pcv valve,i had to open the hood and show him on a common holden car here in australia!
