ahh that was me being sarcastic, evidentally didnt work
I can see the point of frames absorbing impact and deforming, but I think I rather that be material based rather than frame design
The vast majority of frames these days are made to a nice high standard. so that flex is minimal. Unfortunatly, if your material is brittle, the material has no elastic region in the deformation process. IE if you stress it beyond a yield stress, it will just snap, and not stretch. A good example of this is dry wood.
The way Im seeing this, is that if the frame is made out of aluminium, which is a bit more brittle than steel, its more likely to snap because it has a shorter elastic region and thus a lower elastic limit before it snaps. Taking it to the extreme, if you had a rubber frame and gave it flex, would it snap? Of course not because rubber is highly elastic.
Overall, dont get me wrong, I still think aluminium is the best idea for frames. Im just saying its not perfect If anyone doesnt understand please say, ill happily try clarify again.
