The 2025 updates to the Fox Transfer dropper post make this post one of the best performing droppers on the market. The low stack and travel adjustment in 5mm increments allow every rider to get the most drop possible. Incorporating air pressure adjustment into the cartridge, Fox have now brought the Transfer post up to date, allowing the return speed to be tuned. Whilst it’s a little on the heavy side and its one of the more expensive options, the performance on offer is superb.
Fox Transfer dropper post – Technical details
For 2025, the Fox Transfer dropper post sees some changes in design which are intended to improve reliability and usability. Starting from the top, a new two-bolt seat clamp design creates a lower stack height which allows more available drop for the same saddle height.
Under the seat clamp is a Schrader valve allowing adjustment of the internal air pressure. This is new for the Fox Transfer post and allows the cartridge to be recharged up to a maximum of 325psi which can be used to tune the return speed.
Moving down, Fox has introduced new oil seals and upgraded wiper seals which are claimed to significantly extend the service life of the cartridge. Impressively, a 300-hour full-service interval is now recommended for this post thanks to the new seals.
Some friction reduction has been applied to the post in order to achieve a smooth and reliable action. The previous IGUS bushings have been replaced with new metal-backed Ekonol bushings which are claimed to provide faster return speeds. As with all Fox suspension, an extra slippery Kashima coated option is available which increases the smooth action.
Five drop lengths are available ranging from 120mm to 240mm in 30mm increments, however travel adjustment is now included on the Transfer post. By adding shims under the seal head, the travel can be adjusted down by a total of 25mm in 5mm increments. This gives a huge travel range from 95mm to 240mm in 5mm increments so there should be an option to suit every rider and frame combination.
Seat tube diameters are well-covered with the usual 30.9mm and 31.6mm with a new, for the Transfer, 34.9mm as well. A claimed weight for the smallest option (30.9 dia. 120mm drop) is 475g. Available in the Performance Elite (black stanchion) or Factory (Kashima stanchion) and note the remove lever is not included.
Fox Transfer dropper post – Performance
Fitting is a reasonably simple affair with the Transfer dropper post, although a fiddly little barrel is required at the head of the cable – not uncommon.
The actuating lever on the bottom of the post has a small thumb push which, with a strong thumb, makes hooking the cable, with it’s barrel, into the dropper reasonably easy. The two bolt seat clamp is another common design which is simple enough to use.
Before fitting the seat, I recommend checking the air pressure in the cartridge – you’re looking for around 300 PSI (max 325psi). I didn’t do this and after a couple rides had to take the seat back off to adjust this.
Travel adjusting is another simple affair, unscrew the seal head fit the travel spacers – these can be trimmed to the required size. The seal head on my post was hand tight however you may need a strap-wrench if it is more stubborn.
A quick note on weight, the 34.9mm x 240mm post on test is the biggest option and therefore the heaviest coming in at a claimed 826g. As a reference, the equivalent OneUp V3 dropper is 765g. The same comparison at a more common 31.6mm x 210mm sees a weight difference of 129g.
Out on the trails the new Transfer dropper post has been performing quietly in the background just doing its thing. The first few rides produced some grease at the top of the stanchion which needed to be wiped off – this grease is excess from the assembly process. After a couple months, the post wasn’t returning to full extension which prompted me to check the air pressure in the cartridge. With around 130PSI, it was way under the 275-325PSI operating window so a quick pump up to 300PSI and its returning at full speed with no issues. I didn’t check this when fitting the dropper post so a point of note to ensure the pressure is correct on first fitment.
With such a longer post (240mm), the stiffness is impressive. This is, in part, thanks to the 34.9 diameter but even so the operation is smooth, doesn’t bind and feels secure. I can’t comment on the effectiveness of the Kashima coating but in my opinion it’s unnecessary on something like a dropper post where minimal friction and sensitivity aren’t really a priority. On the other hand, I’m a tart for the shiny gold stanchion and it does look great if you’re running Kashima coated suspension.
Fox Transfer dropper post – Verdict
At £389 for the Factory, which doesn’t include the remote lever, the Fox Transfer dropper post is certainly on the higher end of the mechanically operated dropper posts however it is a well-built, refined and totally adjustable offering.
OneUp components are my usual go for a dropper post. The V3 is available in the same range of sizes, tipping the scales a little lighter and a full £100 cheaper it’s a hard offering to look past.
Another high quality offering is the Wolf Tooth Resolve dropper post which comes in at £380. Praised for a smooth and reliable action with low stack, it’s a well performing dropper however the travel adjust could be simpler.
The Fox Transfer dropper post is a beautifully made offering which comes in every conceivable option going. The low stack height, travel adjust in 5mm increments and smooth action make it one of the best performing dropper posts available. There are cheaper options available but the performance on offer justifies the price tag and it’s a little cheaper without the Kashima.
