i saw a rotor agilis crank in the flesh for the first time today, oh my..
Did we learn nothing from the early 90s?
Cutting any highly stressed aluminium alloy component from billet is a fundamentally flawed method. It is sometime necessary, for short run production, highly complex shapes or precise control of external dimensions, but forging is preferred. Shimano can forge hollow cranks, and if you don't have their industrial muscle and expertise, it might be best to leave them to it.
