Nitto S65 Seatpost

The Nitto S65 is available exclusively in a 27.2 mm diameter. Please verify your frame's seat tube size before purchasing, as this is a standard size for many steel and vintage road frames but will not fit frames requiring other diameters.

The S65 features a 30 mm setback. This is a relatively generous offset, making it a great choice if you need to position your saddle further back to achieve your ideal pedaling geometry.

Yes, the single-bolt design is a hallmark of Nitto's precision engineering. When tightened correctly to the appropriate torque, it provides a very secure hold on the saddle rails and is much easier to adjust than more complex multi-bolt systems.

Absolutely. Cold-forging aligns the grain structure of the aluminum, resulting in a seatpost that is significantly stronger and more fatigue-resistant than cast or CNC-machined alternatives. It is built to last for years of consistent use.

The right length depends on your frame's geometry and your saddle height. The 250 mm and 300 mm lengths are typically sufficient for road frames with standard seat tube lengths, while the 420 mm option is better suited for frames with sloping top tubes or if you require a significant amount of exposed seatpost.
