It broke while as I started pedaling when a redlight turned green. In the pics it is possible to see that basically the metal broke ! Was it just a poorly constructed product, or are there some common causes that explain why this happened (like i should have unmounted it and cleaned the dirt out of the screwing lines sometimes or else..). I wouldn't want this to happen to my other pedal.
