Build a Duotone foil that matches how you ride. This package lets you choose each part of the foil separately – front wing, rear wing and mast – and pairs them with Duotone's Aero AL 3BS fuselage, so you end up with a setup tuned to your level and discipline instead of a fixed kit. Every component runs on Duotone's 3BS connection system, so parts stay cross-compatible and you can upgrade one piece at a time as you progress.
How It Works
- Choose your front wing – Free 2.0 or Glide 3.0 SLS. This decides most of how the foil feels.
- Choose your fuselage length – Aero AL 3BS. Shorter is more agile, longer is more stable.
- Choose your rear wing – PX (OG), H or PX. This fine-tunes stability, pump and speed.
- Choose your mast – AL 3BS, Aero SLS or Slim 2.0 D/LAB. This decides stiffness, drag and budget.
Use the charts below to compare the options in each step. Sizes are chosen when you select each product.
Step 1: Front Wing Comparison
| Free 2.0 | Glide 3.0 SLS | |
|---|---|---|
| Rider level | Beginner to intermediate | Intermediate to advanced |
| Wing type | Freeride | High-aspect glide and efficiency |
| Aspect ratio | Low (approx. 6.8–7.2) | High (approx. 12) |
| Construction | Hybrid carbon / fiberglass | SLS carbon |
| Sizes | 1300 / 1600 / 1900 | 825 / 950 / 1100 / 1250 / 1400 |
| Feel | Easy lift, pitch-stable and forgiving, stays composed on tip breaches | Easy low-end lift from a Crest-inspired profile, maximum pump and glide, playful turning and controlled breaches from upturned tips |
| Disciplines | Wing foiling, flat water to small waves | Wing, prone, parawing and downwind (1250 and 1400 for low-energy conditions) |
| Best rear wing | PX (OG) or PX | PX (Duotone's recommended pairing) or H for extra glide |
| Choose it if | You're learning or want a relaxed, confidence-building foil | You want more glide and pump efficiency to ride further on less effort |
Duotone's recommended stabilizers for the Glide 3.0 SLS (wing / foil assist): PX160 for the 825, PX175 for the 950 and 1100, and PX195 for the 1250 and 1400.
Step 2: Fuselage
Every build uses the Duotone Aero AL 3BS fuselage, a high-grade aluminum fuselage with a slim, low-drag cross-section and cut-outs at the wing mounts to save weight. It's compatible with Duotone SLS and D/LAB masts. Pick the length that suits your riding: shorter lengths turn faster and feel more lively, longer lengths add pitch stability and glide for SUP, pump and downwind.
Step 3: Rear Wing Comparison
| PX (OG) | H | PX | |
|---|---|---|---|
| Rider level | Beginner | Intermediate to advanced | Intermediate to advanced |
| Design | Proven PX outline in durable glass construction | High aspect ratio (approx. 8.3–8.5), straight sleek outline | Performance profile with refined twist from root to tips |
| Feel | Stable, dampened and forgiving at low speed | Low stall speed, strong projection and long glide | Locked-in at speed with sharp, precise pitch control |
| Strength | Smooth, predictable turns while you learn | Pumping efficiency and downwind distance | High-speed winging, kitefoiling and bigger, faster waves |
| Best front wing | Free 2.0 | Glide 3.0 SLS (for maximum glide) | Glide 3.0 SLS (Duotone's recommended pairing) or Free 2.0 (smallest size) |
| Choose it if | You want maximum stability and control | You want to pump further and glide longer | You want a faster, more responsive foil |
Step 4: Mast Comparison
| AL 3BS | Aero SLS | Slim 2.0 D/LAB | |
|---|---|---|---|
| Rider level | Beginner to advanced | Intermediate to advanced | Advanced |
| Construction | High-grade aluminum, Helicoil threads | Prepreg carbon | One-piece high-modulus carbon |
| Stiffness | Stiff and direct for an aluminum mast | Extra stiff in bending and torsion, even with large-span wings | Highest – Duotone's stiffest and lightest mast |
| Drag | Low | Lower – sleek 18.2 mm profile | Lowest – tapered profile, drag-optimized base plate and high ventilation resistance |
| Lengths | 60 / 75 / 82 / 90 cm (shortest option for learning) | 75 / 82 / 90 cm | 76 / 84 / 94 cm |
| Choose it if | You want the most affordable, durable mast | You want a clear carbon upgrade without going top-tier | You want maximum stiffness, speed and precision |
Not Sure Which to Pick?
Learning to foil: Free 2.0 front wing + Aero AL 3BS fuselage + PX (OG) rear wing + AL 3BS mast (60 or 75 cm).
Glide and downwind: Glide 3.0 SLS front wing + longer fuselage + H rear wing + Aero SLS mast.
Performance winging: Glide 3.0 SLS front wing + shorter fuselage + PX rear wing + Slim 2.0 D/LAB mast.
