Same iconic stiffness, now with greater sensitivity.

It's difficult to imagine the suspension gurus at FOX improving upon the iconic legacy and performance of their 36 Float Fork, seeing its unbelievable success in the worlds of enduro racing and aggressive all-mountain riding. However, after seeing the integration of EVOL technology into their 36 Float's air spring, we'd be hard pressed to doubt their motives. EVOL technology is borrowed from FOX rear shocks, making an already stout fork all the more sensitive to small bumps and trail imperfections at the top of its stroke.

It retains impressively stiff 36-millimeter stanchions, deflecting torsional forces from bucking you silly across gnarly rock gardens, stupidly steep descents, and bigger park hits. These stanchions employ FOX's Kashima coating for heightened small-bump sensitivity, as well as greater durability when you're thrashing your all-mountain/enduro rig on a regular basis.

The Fit4 damper uses a slightly revised tune with a reconfigured shim stack making it all the more sensitive to inconsistent terrain and small bumps on the trail. Another benefit to this reconfigured design, it's easier than ever to swap volume spacers, as FOX eliminated a seal that you'd normally have to remove in order to add or remove spacers. This is a great feature, as riders of the 36 Float generally seek added progressiveness in the stroke of the fork, especially for bigger hits and rowdy downhill sections.

This particular 36 Float enjoys the 3-position adjustability of its Fit4 damper, which gives you the option of running it Open, Medium, or Firm. In Open mode, you'll find 22 clicks of low-speed compression damping, which is great for dialing in your exact riding preferences to the terrain at hand. Medium gives you a bit more efficiency on those long climbs and smooth trails where stiffening up the front end makes sense. Firm is a practical lock-out, which comes in handy for fire road climbs and asphalt road approaches to the trail.

  • Familiarity: I've used it several times

I was super into the pike! I thought it was the best fork I had ridden.... till the float 36. This thing crashes. The compression feels on point. I don't feel a need for any volume spacers where I did not the pike. Def a great fork and stoked I gave fox a go!

Great fork

    Typical fox quality and ride feel. I recommend getting a few air volume spacers and tweak the rebound and compression to what works best for you. Even off the shelf though, this is a great shock for the high intensity all mountain bike.

    I've been fairly opposed to Fox front forks for a few years now. The 2016 34 I own is ok, but still has a bit of a divey feel in corners and a somewhat dead feel, so I was excited when my Pivot Mach 5.5 shipped with this fork.
    Rockshox has been on point the last few years with the Pike, and this fork gives it a run for its money. It may not be quite as supple off the top as the Charger Damper, but holy crap its a fantastic fork. I am interested to add a few air tokens to make the fork slightly more progressive so I can run a slightly lower air pressure, but so far it has been great!

    What type of riding is the FIT4 damper geared towards vs the FIT HSC/LSC?
