Ye i have stripped loads!, all with oneway.
This was when i was on carpet tho, its fine when your on outdoor tracks!
Put it like this with oneway as you come off a jump and land the front wheels snatch back cause which causes them to snap, The reason they dont snap outdoors cause there is not as much fiction as it lands when theres loads on carpet! Hope that helps, one good thing the gears are alot cheaper than other makes, maybe you could try boiling them? and could i ask what surface they broke on?
