First Look: Fox Transfer Dropper Seat Post

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
