FOX is proud to have been a big part of the innovation. The new Transfer is 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% reduction in air loss over the prior model Transfer was achieved by fully redesigning the internals with an entirely new sealing system. 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.
