Funny this should come up today... I was out riding the other night and kind of noticed anew how aluminum (aluminium) is really sensitive to road feel. OK, bumps are a drag and if my carbon forks and seat post are supposed to dampen vibration, I'd hate to think what this frame would feel like without them. On the flip side, I can really feel the texture of the road under my wheels... I feel *connected* to the road. Whether one likes that, I suppose, is a matter of taste. I do.
Now, I'll grant you I haven't had a lot -OK, *any*- experience with carbon so my observations are a little skewed. I almost feel like my LeMond frame is pretty darned stiff and very responsive. Guess I need to try a CF frame at some point.
