First Look: Fox Transfer Dropper Seat Post

Published: 7th June 2016 | By billy1979

The all-new Fox Transfer seatpost features an infinitely adjustable design with the choice of internal or external cable routing, three drop options, and two lever designs. Low lever force and great modulation make it easy to regulate return speed and small height adjustments.

Low lever force provides consistent actuation pressure even with saddle weighted or unweighted
Two remote options: Left side below bar (for 1x) or Left/Right on bar (for 2x/3x)
Cable actuated with tool-free quick disconnect for easier installation and removal
30.9 or 31.6 diameter
Drop options: 4in (100 mm), 5in (125 mm), 6in (150 mm) • Factory Series models feature Genuine Kashima Coat upper post
Performance Series models feature black anodized upper post

Key Design Features

Internal Post

Spool Valve design offers great modulation, making it easy to regulate return speed and control small height adjustments
All hydraulic internals are housed in the upper post, creating a lighter, more integrated design
Larger diameter hydraulic system translates to lower internal pressures, providing better durability and lighter actuation force at the lever
Other brands use cartridge designs with smaller internals
Mechanical linkage of the Actuation Assembly further decreases lever force

External Post

Benefits from same hydraulic and lever design features as Internal post
Fixed External Actuation Pulley on lower post

Spool Valve

Hydraulic design features large diameter Piston and Spool Valve to regulate seatpost movement
Larger Piston design lessens the force required at the lever and improves durability
Spool Valve integrates a Pressure Relief Valve for an extremely durable design

Pressure Relief Valve

Automatically relieves large pressure variances across Piston
Eliminates pressure spikes and adjusts for thermal expansion in the system
Maintains consistent action during heavy use, cold riding temperatures and extreme elevation changes
Extremely durable design
