Sure. I wonder what would have been the outcome if they took a hardtail, specced it the same but made 4..in each of the materials listed. Lets consider some pros and cons of the materials Carbon Pros: Its light, Its stiff, cool kids / racesnake factor, can be shaped into many forms(molds) Cons: Its expensive, It fails catastrophically Alu Pros: Its light enough, cheap, can be formed into various shapes(hydroforming) Cons: Cant be repaired, got a definite life span ito stresses until without warning it fails/sheers. Unforgiving ito compliance. Not desirable Titanium Pros: Hipster factor, light, frame for life material that doesnt age, compliant Cons: Expensive, standard tubes and forms / specialized skills needed to work on, considered by some to feel spongy so not the stiffest. Steel Pros: Compliant, tough material that won't typically fail or if it fails catastrophically so. Cons: Heavy, ferrous metal that rusts if not treated, flex, cannot be formed into special forms...standard tubes are what is available.
