@ object....quality's not really that much of an issue, we expect these things to get beaten up so disposability may be a good thing...plus isn't a single forged one piece thingamajig stronger?....engineers please correct me.
the whole single forged one peice thing is good for strength in comparison to something thats machined but 1 peice cranks are not strong at all and generally bend so the cranks aren't in line. I used to regularly bend them on my BMX when I was about 12 and I wasn't that fat! I suppose though if your going for shorter junoir cranks these will be alot stronger than standard length BMX cranks if they are made with the same diameters and stuff.
