There are two different Cr1s. The pro and the team issue. They sell the Pro as fully equiped bike. They use different carbon strings and its a little heavier (about 150gr) Not sure about the stiffness though.
The team is stiff 90NM at the bottom and 70NM in the head.
The team issue is available as a frameset with two diff forks to choose. The aero fork is better for all day use cause its real stiff. The light fork is a little flexy and better for lighter racers.
Its alot stiffer than the storck light or any other coca-cola can...
I got my cr1 team issue for 1989 Euros...
Its a hell of a frame.
