I went into a bike shop the other day to test ride a specialized ruby to see what carbon felt like - the bike shop guy was quizzing me as to why I wanted a full carbon bike. I was telling him various reasons, and he just wanted me to bring my aluminum/carbon seat stay bike in so he could help fit it to me. I was telling him I wanted the stiffness, not to mention the road vibration deadening of the carbon & zertz, given that I had pretty crappy wrists... He was recommending a higher angle stem on my current bike, wider tires at lower inflation, and various things like that.

I finally asked him "Aren't you supposed to be trying to sell me this $3k bike?"

I did test ride it and decide that I was fine with my current bikes...

I did appreciate that he wasn't trying to hard sell me the specialized ruby and was being honest in saying that he didn't think I needed it.
