GP Plate mast AX
The all new F4 AX Masts series - Glide Refined, Control Elevated
The F4 AX Downwind Masts bring world-cup carbon engineering into your downwind sessions. Built from 100 % UHM (Ultra High Modulus) carbon with proprietary prepreg layups, its stiffness-to-weight ratio is dialed for maximum responsiveness and efficiency.
Why these masts matter:
Optimized length & stiffness - At 75, 85 and 95 cm, these are the thinnest and narrowest masts in the F4 GP lineup, which means less drag and more precision in turn initiation. F4's Chris calls it “perhaps the stiffest mast on the market.”Drag-minimized connections - A refined tab-and-flange system with just three M6 fasteners ensures a solid, corrosion-resistant connection to your fuselage — all while keeping aerodynamic and hydrodynamic drag in check.
What Riders Are Saying (from the forums)
“Have been on the 95 TE mast … but have just recently received the 75 downwind mast. Since now the focus is riding bumps, I can see the benefit of going shorter.” (Progression Project Forum)
“Overall I’m loving this gear … Super balanced riding, and very playful for cranking turns. Really good low end … The mast is light and stiff … by feel it’s significantly lighter.” (Progression Project Forum)
In the F4 community threads, users consistently praise the 75 cm TE mast’s balance of control, response, and lightweight feel, its value and performance make it hard to beat. (Progression Project Forum)
Please note that the AX masts replace the original 75cm TE Downwind mast.
