hi people
after a couple of kilometres of riding, I experienced the same notches in my back wheel.
when pulling down the chain, it became evident that it had stretched (worn out) and as soon as i would drive over a bump, would be loose enough to jump down and get caught between the tire and the plastic (causing marks).
so i adjusted the tension to "H" and, as expected, the wheel would not run too smooth anymore, basically stop at a certain position.
I figured it would be due to the higher chain tension, and a faulty back axle that now, unlike before when the chain was loose, stopped the wheel.
however, after loosening the screws again, the wheel turned easier (without braking every half turn).
I decided putting the screws in without the little metal rings (washers, shims??) that go between the screw head and bearing.
well I never had a smoother-turning wheel before. seems that the rings grind against the casing of the bearing when installed. (bad design)
Nevertheless i put them back on, as without them the plastic mounting is allowed to move too much and i dunno if that stresses the parts and causes early wear.
Conclusion:
well thats hard. if your back wheel is not turning lightly, try removing them and see what happens. Or maybe install new ones (I have none that fit jet). If you have the time, just post if you experience the same problem, as I am interested if its just my bike.
enjoy riding!
