late-80's 105 cranks: forged or cast?
I've got a 105 road double crankset, came with 52/42 Biopace rings, that came on my 1988 Centurion Ironman Expert. 6-speed indexed (pre-HG cogs) 105 drivetrain, down-tube shifters. I'm curious as to whether this 105 crank is forged or cast.
Also, how much does it matter, and in what ways, whether a square-taper crank is forged or cast construction?
