With its unmistakable golden Kashima coating, the 38 Factory is distinctly recognizable as a FOX, and has long been considered the benchmark fork for enduro bikes. With the latest update, FOX introduced the GRIP X2 damper cartridge, which is claimed to enhance the fork’s performance even further. The question is, can it maintain its leading position with this new upgrade?

Good things take time – FOX seem to have embraced this philosophy by redesigning the popular GRIP2 damper, which held its top spot for over six years. The result is the brand-new GRIP X2 cartridge, which may appear similar on the outside but has been completely re-engineered internally. The GRIP X2 now features a classic shim-stack system rather than the VVC (Variable Valve Control) system of its predecessor.
With the new damper, the FOX 38 lives up to its reputation by still offering adjustments for high- and low-speed compression as well as high- and low-speed rebound, which makes it the only fork in this test with such extensive adjustment options. The high-speed compression (HSC) can be fine-tuned in 8 clicks, while the low-speed compression (LSC) has 18 clicks. The rebound is highly adjustable too: with 8 clicks for high-speed rebound (HSR) and 16 clicks for low-speed rebound (LSR), thus allowing for exceptional flexibility.

The independent high- and low-speed rebound adjustments of the FOX 38 Factory GRIP X2 enable highly refined customization, which allows you to finely-tune the fork’s behaviour to suit your needs and riding style. The low-speed rebound primarily affects the fork’s responsiveness, while the high-speed rebound controls deeper suspension movements, such as hard landings and sharp impacts.
The “+” and “–” markings on the compression adjustment knobs aren’t exactly self-explanatory – “plus” always means more damping, while “minus” means less damping. But don’t worry: the rebound is marked well and a handy table on the right fork leg provides exact guidance for tuning air pressure and rebound, making adjustments straightforward in practice. The clicks on the adjusters are easy to feel and can be adjusted effortlessly even with gloves – a significant improvement over the previous model.
Weighing in at 2,434 grams, the FOX 38 Factory GRIP X2 is the second heaviest fork in this test, and, at €1,660, it’s also among the most expensive options. True to its name, it features robust 38 mm stanchions.
The FOX 38 is available in three versions: the Factory flagship model with FOX’s signature Kashima coating, and the Performance Elite version, which includes the same top-tier GRIP X2 damper but forgoes the golden Kashima coating. However, the latter doesn’t translate into a noticeable advantage on the trail. The budget-friendly Rhythm version, which comes equipped with the less sophisticated GRIP damper and a cheaper chassis, is only available for OEM customers.
The Factory fork comes in FOX’s classic colours, orange and black, as well as a limited gold edition for its anniversary. It’s equipped with the Kabolt X thru-axle, offered in both quick-release and hex-bolt variants. However, the 180 mm brake mount seems outdated compared to modern enduro standards, where 200 mm rotors are common. This means that if you want to run 200 mm rotors, you’ll need to use spacers – a slight drawback. Additionally, the fork offers mounting points for FOX’s proprietary mudguards, available in two lengths for year-round protection without needing zip ties – nice!
The FOX 38 Factory GRIP X2 mtb fork on the trail
On the trail, the FOX 38 Factory GRIP X2 welcomes you with plenty of comfort and control from the get go.Responsiveness is top-notch, particularly in the first third of the travel, where the fork feels extremely sensitive, almost glued to the ground, providing a reassuring sense of security. The fork sits high in its travel without feeling stiff and retains its sensitivity under load, boosting confidence, especially in steep, technical sections.
In the mid-stroke, the FOX 38 provides solid support. It isn’t as firm as the RockShox ZEB Ultimate, but it doesn’t waste any energy either. This balance allows you to build up speed by pumping in flowing sections. In the final third of its travel, the fork shows a pleasant, progressive feel, always keeping a bit of travel in reserve for those “Oh shit!” moments, without up unexpectedly. As a result, the FOX fork is predictable throughout, letting you know exactly how deep in the travel you’re sitting.
Without a doubt, the FOX 38 Factory GRIP X2 is the best fork in this comparison test, which is largely due to thedamper. Unlike many forks that excel in certain areas but reveal weaknesses in others, the FOX 38 seamlessly combines all positive attributes, delivering a comprehensive package that no other fork can match. It offers an impressive blend of sensitivity, precision, and comfort.
