    The M models never switched. The first headshock was around '93 maybe, so that would be the first 1.5.

    Was that even a real 1.5? It was their own version, it definately didn't follow (as it was before) the 1.5 standard.

    Maelstrom's right - - the Cannondale Headshok was not a true 1.5. It was their own proprietary 1.5-ish setup to accomodate the Headshok. I think Cane Creek makes a converter headset to go to 1 1/8", but that's about it. As far as I know, no converter headset or reducer for the newer 1.5 standard will work in a C'dale.

    yes, although they made some 1" and 1.25" early on as well.

    Maelstrom.. I just took a caliper to my headshok steerer and got about 1.560", so I guess they aren't exactly 1.5"... I never knew.

    I just remember lots of discussion about it early on. I didn't remember the details but I do know, reading the 1.5 standard website that headshock wasn't "standard" ...

    It's actually 40mm (1.575").

    My 1991 M400 had a 1" steerer.

    My 1993 Delta V was the 40mm as was my 1999 F1000 and my 2002 Jekyll 700.

    There are adapters out there and Cane Creek does make one from 40mm to 1-1/8". It ain't cheap, but it'll git-er done.
