Fox has released its first wireless electronic dropper post, the Transfer Neo features an unusual battery layout for added clearance, and a claimed actuation time of just 26 milliseconds from lever press to post movement.
Several of the best dropper posts have already opted for an electronic design, foregoing cables for a cleaner cockpit and simplified fitment. Fox wanted to make its dropper post feel instantaneous in action, to achieve this Fox developed its own wireless protocol. The signal is called Neo and Fox claims to be "over 100x faster than Bluetooth and 20x faster than our closest competitor" giving the Transfer Neo a reaction time of just 26 milliseconds.
The post is driven by a Coreless 7V Motor with Fox-customized steel planetary gears to increase durability. Unlike other wireless droppers, Fox has positioned the Transfer Neo’s battery and wireless controller on the top of the outer tube rather than underneath the saddle.
It might not be the sleekest position however Fox says this position improves tire clearance and maintains the ISO-recommended 6mm of clearance between tire and battery. This alternative packaging has allowed Fox to offer the Transfer Neo in a 200mm length, in comparison RockShox Reverb AXS and Magura Vyron max out at 170mm and match the KS Lev Circuit at 200mm. Stack height is reduced too, the 47mm stack height and only 11mm more than a standard Transfer (measured from the bottom of the controller to the center of saddle rails).
Battery life is stated to be between 30 to 40 hours depending on the frequency of dropper post-actuation. The post takes around 1.25 hr to 1.5 hours to charge via USB-A to USB-C cable (supplied).
Fox has based the new Transfer Neo around the same architecture as the 2025 Transfer released earlier this year. Static sealing should reduce friction and air loss and separate air and oil chambers stop the two from mixing. You can also tune the return rate of the dropper post by increasing the air pressure too.
Fox has developed a new lever focusing on giving a familiar feel but a shorter throw. The shifter uses a standard 22.2mm, Matchmaker, and I-Spec EV clamp options and uses a compact design to sit just 36mm below the handlebar. The shifter uses CR2032 battery and is expected to last for around a year. if your shifter runs out of battery mid-ride, the post can be manually activated by pressing and holding the pair button.
The Fox Bike app gives an overview of Transfer Neo components, through the app you can update firmware and activate useful features like Bike Park Mode, Transport Mode, and monitor service interval tracking. Rather than measuring by hours, Fox recommends a service after 8,000 actuations and the app will send you a notification when a service is due. Fox also says the app will display service pricing and details, with the ability to create a service request or pinpoint nearby service locations.
The Transfer Neo will be available in the Kashima coated Factory series and an OEM-only Performance Elite level post. The Transfer comes in three seat tube diameters; 30.9 / 31.6 / 34.9mm and five lengths between 100mm to 200mm. Weight ranges from 528g for the 30.9 diameter 100mm post up to 800g for the 34.9 diameter 200mm.
The Transfer Neo Factory dropper will cost $859 USD / $1149 CAD / €1100 and includes Transfer Neo Post, Lever, Battery, Charger, Cable, and clamping options.
If you need spares, a battery costs $79 USD / $106 CAD / €76.75 and a spare charger and cable: $49 USD / $69 CAD / €61.25.
Our take...
With many components going electronic, it's unsurprising that Fox has released a wireless dropper post. Fox has plenty of experience in dropper post design and the Transfer Neo has some great features, specifically tire clearance and max 200mm length, that set it apart from other options.
One interesting snippet from the press release is Fox's mention that the Fox-specific battery will be "compatibility for future Neo products". While there is no official indication as to what these products are, it's probably a safe bet that Fox is referring to a new version of Live Valve.
I unearthed a Fox Active Valve patent last year which outlined some interesting innovations that could be around the corner. There are a lot of interesting ideas and the release of the Transfer Neo could be the beginning of a new suspension ecosystem from Fox.
