Holy crap!
I just tried out a Giant OCR C2 yesterday. First time I've tried an all carbon bike.
Compared to my aluminum LeMond, it was pretty amazing.
It felt like the was no wasted effort, I stepped on the pedals and the bike moved pretty much instantly.
I was going up some small hills using higher gears than I'm used to.
Picked up my Reno when I got back home, it felt like a pig.
Quick, responsive, smooth... is this what it's all about, then?
My eyes have been opened.
