Intro
Electronically-actuated dropper posts aren’t new — the RockShox Reverb AXS has been on the market for more than five years now — but now Fox has their own take with the new Transfer Neo. So what exactly has Fox come up with? Let’s take a look.
Design
The very broad strokes of the Transfer Neo are similar to the Reverb AXS and a lot of other electronic dropper posts. The Transfer Neo communicates wirelessly between the remote and seatpost, with the remote using a CR2032 coil cell battery (which Fox says should last about a year under regular use) and a swappable, rechargeable battery for the post itself, which is good for a claimed 30 to 40 hours of ride time between charges.
(For reference, RockShox claims “up to 60 hours” of battery life from the Reverb AXS.)
The details, of course, differ more. In contrast to many of the other electronically-actuated dropper posts we’ve seen to date, the Transfer Neo places the battery at the seatpost collar rather than at the head of the post. Fox says doing so allowed them to make the total stack height slightly shorter, but also greatly reduce the possibility of the rear tire hitting the battery at bottom-out with the seatpost lowered all the way. Exactly how much clearance there is will, of course, depend on the bike in question, but Fox says that you should be able to run the Transfer Neo with the collar fully bottomed out on the vast majority of bikes without issue. This arrangement also allows the Transfer Neo to use a conventional two-bolt seat clamp arrangement, unlike the funkier (and occasionally slip-prone) clamp on the Reverb AXS.
The Transfer Neo battery charges on a cradle-style charger, very similar to that of SRAM / RockShox AXS ones, though the two batteries are, unfortunately but unsurprisingly, not cross-compatible. Fox’s charger uses a USB-C connection and a USB-C to USB-A cable is included. Fox also says that the Transfer Neo battery will be used on “future Neo components” but doesn’t expand on what those might be.
Fox says that the inner workings of the Transfer Neo are essentially the same as those of the standard Transfer, apart from the differences in actuation. In contrast with the typical cable-driven actuator on a standard dropper, Transfer Neo uses a motor and gearbox module at the bottom of the post to actuate the valve that controls the post; there’s a wired connection between the battery at the seatpost collar and the motor at the base of the post. Like the standard Transfer, there’s a standard Schrader valve at the top of the Transfer Neo to adjust the pressure in the return spring and thus the return speed.
Despite sharing most of its internals with the new 2025 Transfer, which is fully user-serviceable, Fox says that the added electronics complicate things enough that they don’t recommend at-home service for the Transfer Neo. The recommended service intervals for the Transfer Neo are based on the number of actuations (i.e., how many times you raise and lower the post) rather than total ride time since the former is the more operative thing when it comes to wear and tear on the post. The electronic actuation of the Transfer Neo allows the post to track those actuations, and they’re displayed in the phone app (more on that in a minute) for reference. The collar is still removable for easy re-greasing of the seal and upper bushing, but the Transfer Neo will need to be sent in for a full service of the internals. The Transfer Neo is also rated to IPX7 waterproofness, meaning that it can be submerged up to one meter deep for 30 minutes without issue.
The Transfer Neo is available aftermarket in Fox’s standard gold Kashima-coated Factory guise; a black Performance Elite variant is offered OE (i.e., on complete bikes) only.
Like a lot of modern dropper posts, Fox uses a larger diameter upper shaft for the 34.9 mm version of the Transfer Neo (and the standard Transfer as well); the smaller diameter 30.9 and 31.6 mm variants share the same upper tube. The 34.9 mm diameter Transfer Neo is only available in the 125 mm drop version on up, but there’s a 100 mm version of the 30.9 and 31.6 mm diameters available. Using a larger diameter (and consequently stiffer) upper tube for the 34.9mm diameter post means that Fox can reduce the bushing overlap compared to the smaller diameter versions, and in doing so shorten the total length of the 34.9 mm variant. Fox hasn’t published full length info for the Transfer Neo but says that it has a 47 mm stack height measured from the bottom of the collar to the center of the seat rails, with the post lowered. That is 18 mm shorter than the Reverb AXS and 11 mm taller than the standard Transfer. (For reference, the OneUp V3 has the shortest stack height of any post we’re aware of, at 30 mm for most diameters and 25 mm for the 34.9 mm version.)
Fox has also developed their own wireless communication protocol for the Transfer Neo — which they’ve dubbed… Neo. Fox says that it’s over 100x faster than Bluetooth and 20x faster than their “closest competitor.” Fox says that helps them achieve just a 26-millisecond delay between pressing the lever and the post starting to move. How much that matters in practice for a seatpost is debatable — I can’t say I’ve noticed much of a delay from either other wireless droppers or regular cable-actuated ones — but making the system more responsive can’t hurt.
Remote
The remote for the Transfer Neo looks a lot more like a regular dropper lever than many of the other electronic dropper remotes on the market (especially the AXS Pod controller that SRAM debuted with their Transmission groupsets last year). The Transfer Neo lever has a fairly conventional-looking paddle with a co-molded rubber grip applied. But while the form factor looks similar to that of a normal cable-actuated dropper, Fox says that the Neo lever only needs to travel one-sixth as far as standard Transfer one to actuate and that it has much lighter action in doing so. The short throw also allowed Fox to move the lever farther forward under the bar (i.e., farther away from the rider’s hand) to reduce the likelihood of bumping it inadvertently while riding.
The Neo lever is compatible with a standard 22.2 mm standalone handlebar clamp and SRAM Matchmaker X or Shimano I-Spec EV integrated mounts. The brackets for all three are included.
The CR2032 battery that powers the remote can be swapped tool-free (using the new battery to open the hatch and then the old one to close it again afterward) and an indicator LED on the lever changes color as the battery fades. The phone app also displays the battery status.
If the controller battery dies, the Transfer Neo can be actuated from the post itself by pressing and holding the pairing button until the indicator LED flashes white, actuating the post, and then pressing the pairing button again to lock it in position. You can also open and close the valve via the phone app. Speaking of which:
Phone App
Fox now has a phone app to go with the Transfer Neo. It’s not required to use the post but adds a variety of functionality including a handy pairing walkthrough to connect the remote and post at initial installation; more granular battery status for both the post and remote; tracking of the number post actuations (and a service reminder once it hits the recommended interval of 8,000); the ability to install firmware updates; and toggles for “Transport Mode” and “Bike Park Mode.”
Transport Mode deactivates the “shake to wake” function of the seatpost to preserve battery life when driving with your bike. (You can, of course, also just remove the post battery to accomplish the same thing. Fox includes battery covers and a blanking plate to protect the exposed contacts on the post and battery when they’re separated.)
Bike Park Mode is meant to prevent you from inadvertently raising the post by bumping the remote, especially if you’re doing tricks that involve taking your hand off the bar. Activating Bike Park Mode disables the remote until you either turn Bike Park Mode back off via the app or press the remote four times in quick succession to override it.
Some Questions / Things We’re Curious About
(1) First and foremost, how does the Transfer Neo work — from lever ergonomics and actuation to battery life, long-term durability, and all the other things that go into making a good seatpost?
(2) What upcoming Neo components might Fox have been referring to when saying that the battery developed for the Transfer Neo would be used elsewhere?
Bottom Line (For Now)
It’s no great surprise that Fox has added a wireless dropper post to their lineup — and it’s nice to see it offered in longer lengths than the 170 mm drop at which the RockShox Reverb AXS currently tops out — but how well does the Transfer Neo work, and what sorts of riders are going to find it most worth springing for?
