Ok..... then tell us HOW it works! What is the AMOUNT of difference between the flex of a 'stiff' axle when compared to a 'medium' axle?
Before the metallurgist 'educated' me, I, too, thought that the stiffness of the axle could be changed substantially by changing the 'alloy' of the steel. However, after being loudly LAUGHED at for that view by those who DO know, I was forced to re-consider.
The only way SUBSTANTIALLY to change the stiffness of a steel axle (for example) 50mm axle is to change the WALL THICKNESS (size of the hole down the middle). When you do that, you haven't ONLY changed the stiffness: you have also changed the WEIGHT of the axle and thus the changes in handling cannot ONLY be put down to the stiffness of the axle!
Now..... I am NOT a matallurgist nor an engineer and it is HIGHLY possible that you CAN substantially change the stiffrness of steel by changing something OTHER than the 'shape'..... however, those who DO seem to know keep telling me that you CANNOT! Until I am told differently by someone who DOES know, then I have no choice but to believe them!
If you 'know' that the mettalurgists are WRONG on this one, please enlighten us!
