Balz Pro 905-370-85 Blackbird Kit - Modular backtail or integrated stab 385

Product Description

The Balz Pro 905-370-85 Blackbird Kit is a full carbon foil set developed with Balz Müller for wing foil freestyle, wave, and fast freeride. The combination of the Balz Pro 905 BB front wing, the FC/M full carbon modular fuselage, the Flat 370 stabilizer, and the 85 Blackbird mast offers an ideal blend of speed, control, and stability.

The Blackbird profile ensures early take-off, efficient glide, and extremely direct response, designed for ambitious riders seeking high performance in all medium to strong wind conditions.

Frequently Asked Questions (Q&A)

What is the difference between the 905 and the Balz Pro 805?

The 905 offers more lift and planning support than the 805, making it easier and more forgiving, especially during restarts and touchdowns. It still maintains high speed and excellent maneuverability, but with a slightly "fuller" feel underfoot.

What skill level is recommended for this kit?

The kit is suitable for intermediate-advanced riders who already have good control of wing foiling. It can also be a top choice as a first high-performance setup for those coming from larger, slower freeride foils.

Is it suitable for wave use or more for freeride?

The Balz Pro 905 is a true all-around wave/freestyle/fast freeride, with great fluidity in turns and hold in steep sections. It also performs very well for fast freeride, especially if you enjoy surfing chop and varying wave sizes.

Can I customize the foil's behavior?

Yes, thanks to the modular full carbon fuselage, you can try different stabilizers and use positive or negative shims to modify lift, speed, and feel. This way, you can make the kit more stable and "locked-in" or more free and flowing, depending on your style.

What is the difference compared to the 965 Balz Pro?

The 965 offers even more lift and support at low speeds, making it easier for starting and pumping, but less twitchy and quick in direction changes than the 905. The 905 is the ideal compromise for those who want comprehensive performance across speed, maneuvers, and wave control.

Is the 85 cm mast sufficient for chop and waves?

The 85 cm height is an excellent compromise for handling chop, waves, and touchdowns, with enough clearance for deep carving without breaching the water. It also provides enough leverage for significant jumps and aggressive freestyle maneuvers.
