SR Suntour SP12 NCX 31.6X350mm Suspension Seat Post with Protective Cover Black

This suspension seat post is size 31.6, with a diameter of 31.6mm. It will only fit a size 31.6 seat tube and will not fit 27.2 or any other sizes. The package is an OEM (original equipment manufacturer) package, meaning this item is exactly as pictured and does not include a retail package.

The travel distance of this seat post is 50mm. It has a 25mm setback, which refers to the distance the seat is positioned behind the center of the seatpost. The outer diameter of the seatpost is 31.6mm, and the overall length is 350mm.

The size compatibility is an important consideration when selecting a seatpost. This 31.6mm seatpost is designed to fit a specific seat tube diameter, and using it with a frame that has a different size seat tube would not be possible. The OEM packaging indicates that this is a manufacturer-supplied component, rather than a retail product with additional packaging and branding.

The travel distance of 50mm provides a decent amount of suspension travel, allowing the rider to absorb bumps and vibrations encountered during use. The 25mm setback positioning of the seat helps to distribute the rider's weight more evenly and can improve comfort and control.

The 31.6mm outer diameter is a common standard for modern bicycle seatposts, and the 350mm length should accommodate a wide range of frame sizes and rider heights. It's important to ensure that the seatpost length is appropriate for the specific frame being used to avoid potential issues with insertion depth or interference with other components.

Overall, this 31.6 suspension seatpost appears to be a well-designed and durable component that should provide a comfortable and responsive ride. The specific size compatibility and OEM packaging details are important considerations for ensuring a proper fit and authentic product. With its travel, setback, and dimensions, this seatpost should be a suitable upgrade or replacement for riders seeking improved suspension and comfort on their bicycles.
