RRD WS Full Carbon Front Wing Y26 965: a legacy wing, no longer in RRD's current range. 965 cm², 1,000 mm span, aspect ratio 10.36. The current wings that match it within ±5% area and ±8% aspect ratio, from RRD's own published specifications.
Projected and flat area run 3–8% apart. A marked area is one whose brand does not state which it publishes, so a match inside the area tolerance may be comparing unlike figures.
