(Cliff Claven moment to follow)
I know the CCH Aliens were made from 6061 but the Fixe Aliens ???? I can't find any info on the material they use. The Fixe don't look the same as CCH at all.
Having used Aliens, Mastercams and C4's, their range is:
C4's have the greatest expansion range with Aliens slightly behind and MC's have the least.
In reply to:
Internal cam springs for narrow head width.
Sheath trigger for maximum flexibility. Stainless 5/32" 7x19 wire rope for all Basic Cam sizes.
16 degrees cam angle, soft lobes with teeth for well trusted holding power. Lobes are CNC machined from 6061-T6 aluminum alloy.
Double sheath on trigger. The outer sheath layer has free rotation motion for improved abrasion resistance.
NEW trigger wires system. Flexible and strong while maintaining a correct independent lobe motion.
NEW rounded lobe edges. More consistent rock contact on non parallel cracks and less flash material on lobe edges.
Three well scaled regular sizes from green to red.
Two hybrid sizes. The perfect complement for both Totem and Basic Cams.
CE certified and individually proof tested."
