I have a design question concerning the new Campy Record carbon cranks, and I apologize in advance for my potential lack of proper terminology.
On the carbon cranks the orientation of the hole where the bottom bracket connects to the crankarm one of the corners of the square points down the arm of the crank. On the forged cranks the flat side of the square points down the crankarm, i.e. the "peg hole" of the crankarms are turned 90 degrees from one another. I was just curious as to why. Is it a matter of stresses that are put on one material compared to the other or what? I understand that in use there would be no percieved or felt difference just curious about the choice from a design standpoint.
