More Information

The Ganna AeroFin is a high-performance carbon seatpost engineered to minimise drag through a biomimetic design. Its slim, shark-fin-inspired structure optimises airflow around the seatpost area to improve overall cycling efficiency.

The slim 13 mm frontal profile reduces wind resistance, while the bionic micro-offset shape allows subtle longitudinal flex for ride comfort without compromising lateral stiffness. Each post has a naked carbon finish with a precision laser-fused surface, and the integrated system includes a full-carbon saddle clamp and titanium hardware for a light, secure set-up.

Compatibility

The AeroFin is made for specific frame models, and Ganna develops new fits according to market feedback, covering popular 2026 models, with more under development. The current listing is for the Quick Pro ER:ONE (3 mm setback). For any other frame, choose Contact Us for Other Models or WhatsApp us with your frame model and we will confirm fitment and setback before you order.

Which Length Should I Choose?

✔ 300 mm post: minimum insertion 75 mm, maximum insertion 160 mm

✔ 370 mm post: minimum insertion 95 mm, maximum insertion 230 mm

Measure your exposed seatpost. If it is between 140 and 225 mm, the 300 mm post is recommended. If it exceeds 225 mm, choose the 370 mm post (maximum exposed seatpost 275 mm).
