FOX, Factory Transfer Seatpost F-S, K 30.9mm, 180mm

The fully redesigned hydraulics of the 2025 Transfer feature an entirely new sealing system for enhanced durability. The full-service interval is now at 300 hours, which most riders can do with the tools in their garage. We also used metal-backed EKONOL (PTFE/Teflon) bushings to achieve tight tolerances and the lowest possible friction to allow easier actuation.

The placement of the new air chamber allows riders to recharge and adjust air pressure through a Schrader valve under the seat clamps. Tune to your preferred return speed or adjust for environmental factors such as altitude or ambient air temperature. A metal valve cap with O-ring (the same we use on FOX suspension) ensures zero air leaks through the valve.

We kept the same low stack height and 2-bolt clamp design that riders loved from the previous Transfer, while improving aesthetics and keeping weight to a minimum. With up to 240mm of drop, adjustable travel (down 25mm in 5mm increments) and a dedicated 34.9mm diameter, Transfer reclaims its rightful place as the overall leader in dropper posts.
