Al tubing - tech question.(3 posts)

Al tubing - tech question.Eager Beagle

Does anyone have a link explaining the ins and outs of differing Al tubes? Altec 2+, Starship, Columbus zonal, 6000, 7005, 7020, blah blah etc etc?

I am trying to make an informed opinion on what the real world differences are in these materials, in terms of weight, riding use, construction (1/2/3/butting, normal/compact etc).

Thanks.

It is possible to build a good frame with any of the high performance tubings. The design and the execution of the construction process is far more important than any particular tube. Cannondale builds with 6xxx alloys, while others use 7xxx. Cannondale does sophisticated heat treatment and alignment techniques, along with elaborate tube shaping and wall thickness variations. The tubing alone will NOT determine the performance of the frame. Go with other factors in your decision.
