    Myself and a frame building buddy are working on a Fat bike fork based on a Girvin. If anyone knows what the Al alloy in the fork leg is please share this info with me? Need this info for the welding and/or heat treat if its in the 6000 series.

    Seems the Proflex frames were made of 7000 and maybe the forks were too since this gets around the HT issue.

    Planning to call around to some local recycle/salvage yards to see if anyone has a "sorter" as a backup but that seems remote.

    I built frames in the 90's and remember all the problems people had with this fork. I remember thinking it could have been done much better. A decade later and I am working on my own design kind a cross between a Proflex and the Look Fournales. This is my second post hear on MTBR when I get to ten I will start a new thread of my frames.

    I have a Proflex 754 in the garage, with the Girvin fork. Melted, of course.

    Some company's did make good "Girvin forks"

    I'm not sure if was Nukeproof that made them..

    Shock on the steer tube, very clever.

    Another alternative.

    In my eyes the lack of quality control and cheap manufacturing is what kill the Girvin's but the overall concept is sound..

    That 1st one is a head shock. No linkage. Cool though!

    A truss fork with suspension and curved structural members. Holy wacky wonderland Batman!

    German-A are probably the only guys still making a linkage fork. They are supposed to be excellent.
