Family R Series Brand’s category Downwind Disciplines downwind, sup, wing, pump HM carbon · 2025-2026
The R Series Front Wing runs 7 sizes, 600–1,250 cm², and holds its proportions across the range: every size publishes an aspect ratio within 5% of the others.
Its 935 mm span is 20% wider than typical for the area — the median across the 102 current wings within 10% of its size is 780 mm.
Projected and flat area run 3–8% apart. A marked area is one whose brand does not state which it publishes, so a comparison inside the area tolerance may be comparing unlike figures.
