All Aluminum Isn't Created Equal

[GLC1968]

Question: How do you know a bike is made with the good aluminum? I have been hesitating on the Specialized Tricross with disk brakes (2012 model) because it is aluminum. And I can't test ride it on a really long ride to see if I will like it as much as my Ruby Elite (carbon).

If you see my post above - my husband LOVED his TriCross, despite the aluminum! He actually owned 3 different tricrosses at one point (for other reasons) but felt they all had a ride that felt as smooth as his carbon Roubaix.
