The old ones have had a few years though for the stories of them breaking to get out and it is well known that there was a manufacturing defect with the batch which the broken ones came from. Yes Kris rides these probably daily and he does some insane stuff but he is also a business man. I bought a KH05 on the basis that it was being sold cheap on UDC, by making the hub and cranks cheaper the price of the uni comes down and more people are going to buy them, hence he makes more profit.

I don't know if I trust computer modelled simulations for something like this, I would rather someone set up a jig to hold a hub as if it was in a unicycle and then test it by doing static and dynamic load tests to see what static and dynamic loads cause a failure. Then we would know for certain which is stronger.

I know this comes across as though I don't like/trust Kris when in reality I do like KH products. I don't agree with people saying what is better with no scientific backing for what they are saying (this isn't directed at you kington99 just a general comment about the forum). The new moment hub and cranks may well be stronger but to say they are, based on a manufacturing defect and the fact they are "new" is wrong in my eyes.
