Simple Simon: The internals of the Z.1 were very straightforward—an oil cartridge and a coil spring in each side. External preload adjusters on top of each leg could compress the spring for a little extra stiffness. Since the fork was entirely open bath, the oil was allowed to flow freely throughout the fork and provide the silky-smooth travel.
Proflex 856: Okay, the wrecking crew had mixed feelings about the Proflex; however, that didn’t stop these machines from gracing the trails for many years after this review hit the newsstands. The elastomer single-pivot design held up quite well over the years.
Bulletproof: Sean McCoy gets spicy on the Marzocchi Z.1 fork which is probably the fork that actually made bicycle suspension stick. The coil-sprung 4-inch-travel fork was not only plush and forgiving, but also durable enough to last more than a season. You could probably run sand instead of fork oil in these things and they would still work fine.
