PRO Sirin Performance Saddle

AF stands for Anatomical Fit. This indicates the saddle is specifically shaped to accommodate female anatomy, focusing on pelvic structure to reduce discomfort during long rides.

While it is designed primarily for road cycling, the ergonomic shape can work for gravel riding if you prefer a more aggressive, performance-oriented position. However, it lacks the extra padding or durability features typically found on dedicated mountain bike saddles.

The central cutout is designed to relieve pressure on soft tissue areas, which is a common pain point for female cyclists. By removing material in the center, it allows for better blood flow and reduces numbness during sustained efforts in the drops or on the hoods.

Yes, the PRO Sirin uses standard 7mm round rails, which are compatible with the vast majority of road bike seatposts on the market today.

Saddle comfort is highly personal and depends on your sit bone width. We recommend visiting a local bike shop to have your sit bones measured, as choosing the correct width is more important for long-term comfort than the saddle's padding level.
