Don't know if this is the best place to ask this (new here). This concerns the old "aluminum is harsh-riding" belief. I've found that not to be true on the current bike I'm riding. The ride is better than with the steel frame I had before (and components are identical). But I don't like the short top-tube on the bike and am looking now at a Caad5 frame, which is a better performance frame. My question is whether there is anything about the Caad5 that might bring out the harshness of aluminum that so many people talk about (but that I haven't experienced with my basic Nashbar Al frame). I'm 6'3, about 190 lbs. Thanks for whatever thoughts you have on this.
