DESCRIPTION FROM DUOTONE
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

| 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.
