I have a 95 M1000 with rigid pepperoni fork and a 99 F1000 with Headshok Fatty SL. I just had the Headshok serviced; re-installing it required some home-made tooling this time around, the first time it did not. It rides really nice once up and running. The high maintenance and odd parts make it a bad choice for an only bike. Most of my bikes are steel but a nice Cannondale is good to have. Basically, the frames were pretty unique and well finished but the parts were steaming garbage for their price points.
