premium rush was stunt ridden by mr macaskil, im pretty sure the frames on the bits with the serious tricks in, such as the 360 drop were custom made. Road parts are not designed to take as much force as trials parts and definately not in the same mannor, and as such will not take the abuse. Parts made for dh, xc and even 4x for example are made for comparabile forces, jumping, dropping ect and even these are known to fail. Therefore there is no purpose in you experimenting with a road orientated stem as it simply will not withstand the force. the only experiment here is how long it will withstand it, which will most probably be a very short period of time. I know someone has been told off for being abusive, but seriously if you don't get the message after this response and all of the above replies telling you not to; you are seriously f**ktarded. You are an ignorant, intollerable dickfiend and I turn my back on you. You WILL break your nose/ribs depending on it when it goes and I hope you learn from that experience.
Goodbye.
