This is why I love my OCLV Trek.....has unbelievable road dampening abilities, it's stiff where it needs to be but doesn't beat the crap out of you, and handles great. It just gives an overall great ride. It's technically a "race bike", but it has all-day ride comfort. Best of both worlds, IMO.
Mine "sings" to me as well.....on those rare days when I actually get a tailwind and can hear the drivetrain and wheels whirring along at 26+ mph, with no interruptions from the frame making any noise (since carbon is a non-ferrous material). Took me a bit at first to get used to it....and like many others, I thought it "felt dead" at first, but then I learned to embrace it, and now I love it.
I would really like to try a Ti bike someday though, as it's the only frame material I haven't ridden on yet.
