Fox Transfer Factory Dropper Seatpost 2025 Transfer Rises Again Droppers have come a long way in a few short years, and FOX is proud to have been a big part of the innovation. Fox took their learnings over more than a decade of engineering dropper posts to make the new Transfer smoother, more robust, more tunable, and more serviceable than ever before. With up to 240mm of drop, adjustable travel (in 5mm increments) and a dedicated 34.9mm diameter option, Transfer reclaims its rightful place as the overall leader in dropper posts. A 62% Reducation in air loss over the prior model Transfer. That was the result after fully redesigning internals with an entirely new sealing system. With a focus on enhanced durability, this updated design replaced two dynamic air shaft seals with static seals, lowering overall friction and therefore lowering air loss potential. A 6X increase in duty cycle life came from doubling the oil sealing and adding a wiper. Less oil loss means less maintenance, longer life and reduced overall air loss from air dissolved in the oil. The air chamber is now at the top of the post which eliminated dynamic air seals and allowed Fox to add a Schrader valve for riders wanting to adjust air pressure. The Schrader valves come with O-ringed metal caps that are proven to not leak. Less Friction. More Durability. Easier Actuation Another upgrade for the 2025 Transfer was the move from IGUS bushings to metal-backed Ekonol bushings throughout Transfer's internals. Ekonol bushings achieve tight tolerances with the lowest possible friction, allowing riders easier actuation (less force to break stiction and lower the post). Transfer now has a 300-hour full-service interval, which riders can do themselves without the need for any special tools or equipment.
