At the Enduro World Series race in Ireland, we were able to marvel at Fox's new Vario seatpost on Greg Callaghan's Cube bike. As it already appeared to us to be visually mature, it was obvious that the new throne would soon be officially presented. Now our speculations are coming true.
Fox's Transfer dropper post replaces its predecessor "Doss". It differs significantly in terms of design and cable routing. Both Transfer models "Factory" and "Performance" come with cables for internal or external cable routing. The external cable guide is no longer located at the head of the new post, but has been moved down to the lower tube. The annoying removal of the cable is therefore no longer necessary.

The supports are operated via the new thumb levers, which are said to be characterized above all by their ease of movement. As already mentioned, there are two levers: one for 1x shifting systems where the thumb lever is mounted on the left under the brake lever, and a lever that is used for 2x systems and can be mounted on the left or right. The extension speed can be easily adjusted on these.

The Factory and Performance versions are available with 100, 125 and 150 millimetres of continuously adjustable stroke. The two models differ in the coating of the dip tube. Like the suspension forks, the Transfer Factory comes with a Kashima coating. The dip tube of the Performance seatpost, on the other hand, is anodized black. The Transfer is available in the two common seat tube diameters 30.9 and 31.6 millimetres.

Inside and assembly

• The control valve inside the post offers a large adjustment range so that the return speed is easy to regulate and allows controlled, small height adjustments.
• In order to save weight, all hydraulic components are housed in the upper part of the seatpost
• The larger diameter of the hydraulic system reduces the internal pressure. Above all, this improves durability and reduces the force required on the thumb lever.
The External model has the same hydraulic design, but the system is controlled via the small, external deflection pulley.The spool valve integrates a pressure relief valve, which makes the system more robust. This automatically relieves large pressure deviations above the spool and eliminates pressure peaks, for example caused by thermal expansion in the system due to intensive use, very cold temperatures or use at high altitudes.

According to Fox, installing the transfer is relatively simple. This is well illustrated in the following video under the following link.
