Description
The Dedicated Rear Wing for the AFS Pure High-Aspect System
The AFS Pure Stabiliser is the rear wing developed in tandem with the AFS Pure front wing range — an integrated system designed for riders who want to push performance further into the high-aspect, high-glide end of the spectrum. Three variants cover different riding styles and front wing pairings: the 145 and 150 are standard-aspect stabilisers offering control and carving precision, while the HA135 is a high-aspect option tuned for maximum glide and pumping efficiency when paired with the Pure HA front wings.
The entire Pure range is built on the AFS Fuselink system and manufactured from full carbon in France, making it directly compatible with the broader AFS foils ecosystem.
Who It's For
The Pure Stabiliser is for riders who have invested in the AFS Pure front wing range — particularly the Pure 700, Pure 800, and Pure HA 800 — and want a rear wing tuned to match it precisely. The 145 and 150 suit wing foilers and freeride foilers who want solid control and carving character. The HA135 is the dedicated partner for the Pure HA 800 in downwind and long-distance wing foiling — it prioritises glide and drive for pumping over tight manoeuvring. It suits intermediate to advanced foilers across wing foiling, SUP foiling, and downwind disciplines.
Key Features
- Three variants: 145 cm² / 150 cm² (standard) and HA135 (high-aspect)
- Pure 145: 145 cm² surface area, 350 mm span, flat dihedral for maximum control
- Pure 150: 150 cm² surface area, 325 mm span, dihedral and arrow shape for manoeuvring roll
- Pure HA135: high-aspect profile, ~135 cm² surface area — glide, efficiency, drive for pumping
- UHM (Ultra High Modulus) carbon and carbon/Kevlar construction
- AFS Fuselink compatible — fits all current AFS fuselages
- Supplied with screws and protective cover
- 100% made in France
On the Foil
The Pure 145 and 150 take different approaches despite similar surface areas. The 145 runs a flat dihedral, which means it provides consistent, planted support — ideal when you want maximum control and precision, or when riding in more demanding conditions. The 150, despite being slightly larger in nominal area, uses a dihedral-and-arrow geometry that frees up roll more than you'd expect: it carves intuitively and changes direction with less effort. Both are stiff, direct, and fast to respond.
The HA135 is a different proposition entirely. Pair it with the Pure HA 800 and the foil enters a different performance envelope — lower drag, longer glide between pumps, and real drive when you push down to pump back to height. This is a setup built for covering distance efficiently, whether that's downwind, light wind wing foiling, or linking runs without the wind helping.
Compatibility and Setup
All three Pure Stabiliser variants connect via the AFS Fuselink system — two M6 screws to any current AFS Fuselink or EVO fuselage. AFS recommends pairing the Pure range with a Performer or UHM mast to exploit the full performance potential of the foil system. The HA135 is specifically recommended for use with the Pure HA 800 front wing for downwind use. The 145 and 150 pair well with the standard Pure 700 and Pure 800 front wings for freeride and wave riding setups.
Construction
The Pure Stabiliser uses a combination of Ultra High Modulus (UHM) carbon and a carbon/Kevlar layup — the same specification used across the Pure front wing range. UHM carbon delivers an exceptional stiffness-to-weight ratio, while the Kevlar element adds impact resistance and durability without adding significant mass. All components are manufactured in France to AFS's usual production standard.
Size Guide
| Variant | Surface Area | Span | Best For |
|---|---|---|---|
| Pure 145 | 145 cm² | 350 mm | Control-focused freeride, demanding conditions, flat dihedral for planted feel |
| Pure 150 | 150 cm² | 325 mm | Carving freeride, roll-friendly geometry, works well across most Pure front wings |
| Pure HA135 | ~135 cm² | HA profile | Downwind, pumping, light wind — paired with Pure HA 800 front wing |

Why We Stock It
The Pure Stabiliser is the component that completes the Pure system properly. AFS developed it alongside the Pure front wings specifically so that pitch balance, lift character, and turn feel are dialled in from the start. If you're riding a Pure front wing with a generic stabiliser, switching to the matched Pure stab is one of the most straightforward performance gains available — no guesswork, no trial and error.
FAQs
What do the Pure Stabiliser size numbers mean?
The 145 and 150 refer to surface area in cm². The HA135 refers to a high-aspect variant with approximately 135 cm² surface area and a longer, narrower planform. Despite similar surface areas, the three variants have quite different ride characters due to their geometry — the 145 is flat and planted, the 150 has a roll-friendly dihedral, and the HA135 is a genuine high-aspect design for glide and pumping.
What's the difference between the Pure 145 and Pure 150?
Despite the 150 having a slightly larger nominal surface area, it actually feels more manoeuvrable than the 145 because of its dihedral-and-arrow geometry. The 145 uses a flat dihedral, which prioritises control and stability — it's more planted and direct. The 150's design frees up roll, making it more responsive to weight shifts and easier to carve. For confident intermediate to advanced foilers, the 150 is often preferred; for those who want the most control in challenging conditions, the 145 is the pick.
Which Pure Stabiliser pairs with the Pure HA 800 front wing?
The Pure HA135 is the recommended partner for the Pure HA 800 front wing, specifically for downwind use. AFS designed this combination to maximise glide and pumping drive — the HA135's high-aspect profile complements the HA 800's efficiency-first character. Using a standard Pure 145 or 150 with the HA 800 is possible but doesn't make the most of the front wing's performance envelope.
Is the Pure Stabiliser compatible with non-Pure AFS front wings?
Yes — all three Pure Stabiliser variants connect via the standard AFS Fuselink system and are physically compatible with any current AFS Fuselink or EVO fuselage. That means you can use the Pure 145 or 150 with Silk, Enduro, or Performer front wings if you want to experiment. However, they were developed and optimised specifically for the Pure front wing range, so they will feel most natural in that combination.
Do I need a specific mast to use the Pure Stabiliser?
The Pure Stabiliser is compatible with any AFS Fuselink mast and fuselage, but AFS recommends a Performer or UHM mast to get the most out of the Pure foil system. A stiffer, higher-performance mast reduces energy loss at the mast/fuselage interface and lets the foil perform as intended. That said, the Pure stab will still work correctly on an EVO mast.
Can I use the Pure Stabiliser for kitefoiling or windfoiling?
The Pure Stabiliser is designed primarily for wing foiling, SUP foiling, and downwind foiling. It is physically compatible with any AFS Fuselink fuselage, so kitefoilers and windfoilers running AFS gear could technically use it, but the Pure range is not specifically marketed or optimised for those disciplines. Contact us if you want to discuss compatibility for your specific kite or windfoil setup.
