The biggest concession the USD platform makes compared to a regular fork is weight.
By removing the arch – which is one of three cross-bracing points, the axle and crown being the other two – Fox has had to beef up the remaining sections.
The 'overbuilt crown' (Fox's words) and 20mm axle, along with chassis-tube thicknesses, culminate in a 2,730g weight for the 170mm-travel, 225mm-long steerer model.
In comparison, a 170mm-travel ZEB Ultimate Charger 3.1, also with a 225mm-long steerer, weighs 2,320g – a full 410g less.
Fox Podium Factory performance
Along with attending the Fox Podium Factory fork press camp in Leogang, Austria and riding lift-assisted world-class trails, spanning from massive vomit-inducing high-speed bike-park berms and jumps through to the incredibly technical stages used in the enduro World Cup, I also rode extensively at home.
Scotland’s Tweed Valley – arguably the UK's premier enduro riding destination – gave the fork a true workout.
With the rough ground littered with rocks and roots, high-speed G-outs, and tight twisty trails, the variety of the Tweed Valley's trails is like a torture rack for suspension and bikes.
Fox Podium Factory setup
A 170mm-travel Podium was fitted to my 2025 Marin Alpine Trail enduro bike, replacing a 170mm-travel RockShox ZEB I’ve been riding.
The axle-to-crown height of the Podium is only fractionally taller than a ZEB, so no bar-height adjustments were needed to maintain my bike’s familiarity.
Fox’s own research and development expert, Ariel Lindsley, helped me set up the fork, recommending similar pressure and volume-reducer spacers to the 38.
For my 78kg weight, the Podium’s air spring was inflated to 90psi, and two 5cc spacers were installed.
Ariel also helped me set the fork’s compression and rebound-damping adjustments.
He set the high-speed compression adjuster to +5 clicks from fully open, and the low-speed compression adjuster to +10 clicks from fully open, both sitting exactly halfway in their adjustment range.
After I explained I like a fast rebound, he set the low-speed rebound adjuster to +2 clicks from fully open and the high-speed rebound adjuster to fully open.
During the initial ride and throughout subsequent testing at home, I’ve experimented with different settings, but ended up with 87.5psi in the air spring, with five 5cc volume-reducer spacers.
Fox Podium Factory ride impressions
Load up the Podium with aggressive, high-paced riding and it barely flinches.
Criticising it for feeling flexy doesn’t wash; steering accuracy is on a par with the most robust single-crown forks out there.
Steering-input vagueness and wandering are non-existent, no matter how hard you’re pushing the front wheel in a berm, or if you’re turning hard through a compression.
Accidentally overloading your front wheel in the tight pocket of a berm, resulting in a one-rep max push-up doesn't reveal any unwanted twist or flex.
Here, the fork remains straight and true, tracking flinch-free on your chosen trajectory.
Riding steep, sharp, on-the-brakes turns, littered with rocks and roots, is borderline revelatory. Aside from the fork’s chassis remaining steadfast under these massive loads, it’s also able to track the ground’s bumps predictably and smoothly.
Regardless of how hard you're wailing on the brakes or how large and sharp the bumps you're hitting are when you're hurtling down a steep, rough chute into a sharp turn, the fork remains plush, calm and composed.
Its ability to absorb bumps of this nature in those circumstances is one of the standout characteristics that separates it from traditional designs.
Whether it's the bushings binding less, the GRIPX2 damper's new tune, the air spring or a combination of those things – which is most likely – it's magically smooth where other forks aren't.
Insulating your wrists and hands from negative inputs to reduce fatigue is one bonus, but the ultra-sensitive, ground-smoothing action, and therefore boost in traction, is the biggest and best bit.
Not only is grip impressive – because the front wheel spends more time in contact with the ground – but so is steering control.
Where traditional forks wouldn’t be able to absorb the bumps as effectively, the Podium moves smoothly and calmly in and out of its travel, providing excellent steering feel.
It’s much harder to wash out or understeer the front wheel. Imagine a steep flat or slightly off-camber corner strewn with rocks and roots; you're loading the front wheel for grip and trying to slow down or control your speed with the brakes.
Here, the Podium's forgiving, searching out grip where there is usually none, flexing, absorbing and tracking the ground's distortions impeccably.
Ride a section of linked-up turns like I described above, and the Podium comes out swinging – grip, control and fun are all doled out generously.
There’s also a somewhat ethereal element to the performance, especially when tracking across cambers strewn with embedded rocks and roots.
With a traditional fork, striking diagonal rocks and roots hard enough with the front wheel can lead to the tyre scraping along the root or rock’s side, or the bar getting twitched in one direction or another, both requiring emergency measures to retain control.
I’m not saying the Podium is a cure-all panacea for your off-camber riding needs, but it definitely feels smoother, quieter, less hectic and calmer than a traditional fork in the scenario described above – and everywhere else.
Fox Podium Factory bottom line
The Podium is an excellent USD debut for Fox; damper, spring, chassis and design all come together to provide one of the smoothest and grippiest forks on the market.
While each element of its performance isn't necessarily leagues ahead of other offerings on the market, when you combine them and really push through hard terrain, there's something special and intangible about how good this fork feels.
Yes it's heavy, and yes it's very expensive, but if either of those things are causing you concern, the Podium probably isn't for you anyway.
Riders willing to spend big money for what is essentially an incremental – albeit important and noticeable – performance gain should fast-track the Podium to the top of their purchase lists.
