Mcfk Open Full Carbon Saddle

The MCFK Carbon Saddle combines extremely low weight with a flexible full-carbon construction designed to provide support and compliance without relying on conventional foam padding. Manufactured in Germany, the saddle uses a thin carbon shell that can flex subtly under load, helping maintain comfort while keeping weight exceptionally low.

Its shape features a relatively broad nose and a smooth transition from front to rear, allowing riders to move naturally between positions during long rides, climbing, and harder efforts. MCFK offers the saddle in 130, 135, and 140 mm widths to accommodate different rider fit requirements.

Depending on configuration, MCFK saddles are also available with an open pressure-relief cutout for riders who prefer reduced central pressure, as well as padded versions that add surface grip and additional cushioning. The padded surface can be particularly useful for riders who prefer a more planted position when riding aggressively or spending extended time in the drops.

The 7 × 9 mm oval carbon rails are bonded directly to the carbon shell and reinforced with woven carbon for strength and impact resistance. These oversized carbon rails require a compatible seatpost clamp and are generally best suited to seatposts that clamp the rails from above and below rather than directly from the sides.
