Select your front wing with numbers, not guesswork.

FrontWings

Pick two or three front wings and your conditions, then compare take-off and stall. Same fuselage, same stab, same mast: the difference comes from the front wing.

Weight carried versus speed Three curves per front wing: what it carries cruising, at the comfort limit and just before stall. Where your weight crosses each curve you read your cruise, comfort-onset and stall speeds. Hover to read values.

Legend

Year and price: The first two rows of the table: the release year when the brand publishes it, then the public price. Price taken from the brand's or a retailer's website on 9–10 October 2026, in euros, excluding any discount. When the brand does not sell in euros (Armstrong in dollars, Indiana in Swiss francs), the price comes from its reference European retailer and carries an asterisk. The price links to the page where it was found.
Span: Width of the front wing from tip to tip. The longer it is, the more stable the wing and the further it glides, but the slower it banks and the more easily a tip breaks the surface in tight turns.
Aspect ratio: Span² / area. A long, narrow wing has a high aspect ratio (12 and above): it glides better and pumps further. A short, wide wing (6 to 8) is more nimble and playful.
Thickness (t/c): Maximum thickness of the section divided by its width, in %. A thick section lifts better at low speed and stalls gently; a thin one is faster but stalls more sharply. This is what sets the max lift coefficient.
Comfortable speed range: From the speed where the required coefficient is 0.7 (below it you must pitch up and work) to the speed where it is 0.5 (cruise). The window where the wing carries you effortlessly for your weight.
Carving index: Agility in turns, score from 0 (very stable) to 10 (very playful), computed from span (a short wing banks quickly and rarely ventilates in tight turns) and aspect ratio (low = playful, high = glide). It ignores sweep, anhedral and the section.
Power needed: What the rider must produce to hold the chosen speed: total drag (lift, wing friction, mast, fuselage and stab) times speed, divided by pumping efficiency (60 %). The runner equivalent is the speed a 75 kg runner would hold on the flat at the same power (0.3 W per kg per km/h, the order of magnitude of running power meters), with the pace in minutes per mile. Order of magnitude within ±20 %; comparing two wings is more reliable than the absolute figure.
Most economical speed: Speed where the power needed is lowest without working hard, that is without dropping below the start of the comfortable range. For a big wing it is often the bottom of that range: it is built to go slowly.
Energy: Power divided by speed: what each mile costs. An e-bike uses about 16 Wh/mi, a relaxed cyclist 25 to 30 Wh/mi.
Flight regime at the chosen speed: Sums up the effort asked of the front wing to carry your weight at that speed, measured by the required lift coefficient (the number shows on hover). Cruise: it carries you effortlessly. Comfortable: normal range. High angle of attack: you must pitch up, little margin. Near stall: at the limit. Does not fly: even fully pitched up, it cannot carry this weight at this speed.
