Cannondale Hollowgram SL 27 Knot Carbon Seatpost

The Hollowgram SL 27 Knot Carbon Seatpost is made for riders who want to add a more aerodynamic and refined component to their race-focused road bike. Designed to suit modern performance machines like the SuperSix Evo and CAAD13, it combines speed-focused shaping with a sleek premium finish.

Lightweight Carbon Advantage: Built from premium carbon fiber, this seatpost keeps weight low while delivering the clean and high-performance feel expected from an advanced road component. It adds a race-ready character to the bike without compromising the polished look of the overall setup.

Designed to Cut Through the Wind: Its truncated D-shape is created to improve aerodynamic efficiency by reducing drag at the seatpost area. This makes it a smart choice for riders looking to support the fast, streamlined design of their bike with a component that is built for speed as well as style.

Comfort with Precise Fit: SAVE technology helps dampen road vibrations for a smoother ride feel, while the two-bolt head allows fine adjustment of saddle angle with secure and reliable clamping. This gives riders a better balance of comfort, fit precision and confident support on hard road efforts.

The Cannondale Hollowgram SL 27 Knot Carbon Seatpost delivers aero shaping, carbon performance and fine saddle adjustment in one premium upgrade.
