There were a lot of aluminum chips whittled off that 70kg block of aluminum.

Didn't Cannondale do a prototype CNC frame back in the early 90"s?

edit - Yes, they did! The Magic Motorcycle concept bike....

Ah, those were the days!!! The bike concept by Alex Pong blew my mind. It featured so many novel ideas revolving around intricate machining. Believe Cannondale bought Magic Motorcycle (Pong's place) and started offering their cranksets under the CODA in-house brand in 1994. Was featured very prominently in their catalog that year. Their top-of-the-line offerings had a spider with only 3 arms!! Wonder how flexy that was?

Magic Motorcycle/CODA was, I believe, the first to offer hollow crankarms.
