    6000 series al vs. 7000 series al frames

    i'm looking at getting a lower-end al frame for racing next spring. i've got my eye on two frames at www.nycbikes.com. one is 6000 and the other is 7000. i have not ridden al for about six years--a way-too-stiff cannondale.

    i will only be able to test ride the 7000 frame because the 6000 is not built up yet.

    i realize that frame material is often not the primary factor in how a bike rides/handles. geometry and componentry play a huge role.

    that said, can anyone give me opinions on the differences between the two?

    TIA

    I would be very surprised if, in a blind study, anyone could tell the difference between the two. It won't matter.

    Bad idea to ask for opinions here, I'm an engineer so I'm biased. ..

    You can see it this way. 6000 series and 7000 series are just two aluminum wrought alloys with slight different in composition. They generally do not have significant difference in terms of strength nor stiffness. Even the doped Al alloys like Sc7000 scandium are not that much stronger than normal ones (if it is any stronger).

    Chances are if you do feel a difference in ride quality between the two, it is the construction of the frame or the difference in components. After all it is the same material.

    I have given longwinded, pedantic lectures on material properties in this forum before. That isn't what team sheepshead was looking for. I know the differences in materials, and I stand by what I said. I doubt anyone could tell the difference between two frames if one were made from a 7000 series aluminum and another were made from a 6000 series aluminum.
