FOX FLOAT Factory Rear Shock

Earlier this year, Fox revised their full line-up of air shocks. All-new for 2023 (technically a 2024 model), the new Float slots into the range between the super-light Float SL and the more elaborate Float X, taking aim squarely at the trail bike market with a stated goal of reducing the weight while maintaining the performance at Float X levels. We’ve had a couple of samples out on the trails for a couple of months now, and we’re here to report on how we’ve been getting along.

2024 Fox Float Shock Highlights

• Float X performance in a lightweight inline package
• NEW larger piston, valving and IFP for wider range of tuning and better damping control
• NEW larger volume EVOL air spring for lower pressures, more linear suspension action, better small bump performance, and better grip at the tires
• NEW Smaller increment (0.1) hybrid volume reducers for ultra-precise tuning
• MCU bottom out bumper for end stroke progressivity
• NEW 2-position switch for zero pre-load on valve stack when in “Open” mode, and (factory) tunable “Firm” mode
• Inline design offers improved water bottle clearance compared to reservoir shock, also great for e-MTBs
• Remote compatible
• Metric Sizes: Std Eyelet 170, 190, 210, 230 Trunnion 145, 165, 185, 205
• Factory, Elite, and Performance Series
• 293g for 170x35
• MSRP: $349 - $499 USD

Initial Impressions

The new Factory Float showed up looking kinda like the old one. That is to say, covered in shiny Kashima with a distinctly Fox-like personality. It is however an all-new shock, with plenty of updates to discover.

The piston is larger, which Fox says helps provide a wider range of tuning possibilities and “better damping control”. The air spring is also larger, and there are smaller-increment volume spacers for more precise air spring tuning. Finally, there’s also a new 2-position switch offering open and firm shock modes, with three further low-speed compression settings available to choose from within the open mode. High-speed compression damping is set from the factory, as is the platform of the firm mode.

Fox’s goal with the new Float was to provide near Float X levels of performance without the superfluous weight. As such, the Float lacks a piggyback reservoir but it does use a larger shaft diameter and an overall beefier chassis compared to the Float SL. Fox says it can still deal with the rigors of aggressive trail riding, so that is what we set out to find out.

On The Trail

We were sent two shocks for two different testers, one went on a YT Izzo and one on a Pivot Trail 429. Both shocks were delivered with the OEM tune that Fox would supply for these bikes respectively.

Both testers found the shock easy to set up. We did not have to play around a lot to find the correct air pressures and damping settings for our test mules. The shock provides a good amount of support out of the box, and we rarely felt the need to add any low-speed compression to help the bike settle in, opting instead to run the open mode in the fully open setting (remember that you can adjust the amount of compression damping within the open mode to three different levels). Both of these bikes feature a good helping of progressivity in their rear linkages, so this was to be expected – but it’s good to know that the option to crank up the damping within the open mode is there for more linear frames. As for the climbing mode, it is definitely on the firmer side of the spectrum, providing a near-locked out feeling that makes it more suitable for fire road climbing than charging your way up technical sections (note that if you need a different platform setting, your Fox service center should be able to tune that for you).

As the trail pointed downwards, we were impressed with the amount of suppleness and poise on tap from such a “small” shock. The ramp up was spot-on and both bikes were well balanced between big-hit absorbability and small bump compliance. Traction was plentiful and the shock did indeed behave as advertised – a Float X without the piggyback.

As things got chunkier, the Float never seemed to be overwhelmed, and even our heavier tester commented that he was surprised at how well the shock kept up as things got rowdy. Bottom-out events were well controlled, and the rebound damping kept the bike feeling settled even as we pushed harder. We did not manage to really rack up the vert on these bikes to see if we could provoke any damping fading on longer runs, but the shock has handled everything we’ve been throwing at it so far without leaving us wishing for a piggyback or a “bigger” shock.

Things That Could Be Improved

We really do not have a lot of complaints to offer here, but if we’re nitpicking, the rebound adjuster is pretty sticky and the edges are sharp, making it less than pleasant to manipulate. Having said that, you wouldn’t expect to have to play around with that one a lot, so it’s really not a big deal. Also, as mentioned previously, the platform setting is super firm. Whether you see that as a positive or negative depends on your trails and your riding style (and the firm mode can be tuned by a Fox service center if you need it to be less harsh).

Long Term Durability

We’ve not had enough trail time with the new Float to make any definitive statements about durability, but we’ve pushed the shock pretty hard so far and it’s still behaving as it should. We’ve had good luck in the past with Fox’s smaller shocks, so chances are you should be able to look forward to many happy miles with the new Float.

What’s The Bottom Line?

When Fox set out to redesign the Float, they did so with the stated goal of providing near Float X levels of performance without the weight penalty. Based on our experience with two different bikes so far, we’d say they have succeeded. The new Float provides a near-perfect mix of suppleness and support, with enough reserves to deal with higher speeds and heavier riders even as things get rowdy. Doing so without taking up too much space in the frame and without weighing down your trail bike build is the cherry on the cake.

About The Reviewers

Johan Hjord - Age: 50 // Years Riding MTB: 18 // Weight: 190-pounds (87-kg) // Height: 6'0" (1.84m)

Johan loves bikes, which strangely doesn’t make him any better at riding them. After many years spent practicing falling off cliffs with his snowboard, he took up mountain biking in 2005. Ever since, he’s mostly been riding bikes with too much suspension travel to cover up his many flaws as a rider. His 200-pound body weight coupled with unique skill for poor line choice and clumsy landings make him an expert on durability - if parts survive Johan, they’re pretty much okay for anybody. Johan rides flat pedals with a riding style that he describes as "none" (when in actuality he rips!). Having found most trail features to be not to his liking, Johan uses much of his spare time building his own. Johan’s other accomplishments include surviving this far and helping keep the Vital Media Machine’s stoke dial firmly on 11.

Jonathon Simonetti - Age: 28 // Years Riding: 19 // Height: 6'4" (1.93m) // Weight: 225-pounds (102kg)

Jonny started mountain biking in 2003 after a trip to Northstar showed him how much more could be ridden on 26” wheels than on a BMX bike. He began racing downhill in 2004 and raced for 12 years until ultimately deciding having fun on a bike was more important than race results. After working as a mechanic in the industry for a few years and developing a deeper understanding of bikes inside and out, he has an aptitude for pairing his riding ability with the analysis of bikes and breaking down what makes them work well. He spends most of his time between trail rides and skatepark sessions with occasional days on the downhill bike.
