Has anyone ever ridden a R2.5?

For so much press and team CSC riding them, I’ve heard almost nothing about them. Does anyone have any feedback? Also, are there bike stores that can even get one? Thanks in advance - E

I’ve ridden one using Mr. Tibbs’ new-school method of product testing: in my head. Actually riding one would be old-school thinking.

I think everyone else is using the same method for now.
