Kurt Sperry wrote wrt Ti brakes but I want to pick up at the end: <snip>:

If one did a Magistroni or Williams style cottered thin arm crank in good Ti alloy, other than perhaps being a bit flexy, I think it might make a dynamite superlight crank even by modern standards.

I have a Duprat steel cottered crank that is only 3 gm heavier than at TA aluminum with the same 5-pin ring attachment. It is slender, octagonal in section, and HOLLOW. Clearly built-up, with separate pedal threading, shaft, and crank-attaching parts. It is wonderful eye-candy - except that you have to look down to see it when I'm riding my early Paramount... So, making a light TI crank would be straightforward, but making it as pretty would be hard -- unless you like weld marks.
