The PRO Sirin Performance is a gender-neutral, high-performance saddle designed for riders who demand comfort across various terrains, from smooth tarmac to rugged gravel. Engineered with a slightly wider nose and a shorter overall length, it caters to those who maintain a powerful, aerodynamic position while needing a stable platform for technical handling.
Built with a carbon-reinforced polymer shell and lightweight stainless steel rails, the Sirin balances elite stiffness with enough compliance to dampen high-frequency road and trail vibrations.
Carbon-Reinforced Shell: Provides a stiff, efficient base for maximum power transfer while significantly reducing the overall weight of the saddle.
Large Central Relief Zone: Features a wide, anatomical cutout designed to alleviate pressure on sensitive soft tissue, preventing numbness during long endurance efforts.
Lightweight EVA Padding: High-density, super-lightweight padding offers a firm yet supportive feel that doesn't "bottom out" over the course of a long ride.
Slightly Curved Profile: Optimized for riders with moderate pelvic flexibility, offering support for those who like to shift their weight slightly during climbs or descents.
Smooth PU Cover: Minimizes friction with cycling shorts to prevent chafing and is highly resistant to water and trail grime.

Mixed-Terrain Riders: If your rides involve a blend of road and gravel, the Sirin’s robust construction and supportive padding handle the transition between surfaces perfectly.
Riders Seeking Pressure Relief: The extra-wide relief channel is one of the most effective in the PRO range for those who struggle with perennial pressure.
Aerodynamic Positioners: The slightly shorter nose allows you to rotate your pelvis forward into an aggressive "on the drops" position without the saddle nose interfering.
Weight Obsessives: While light at ~210g, riders seeking the absolute lightest setup may prefer the carbon-railed PRO Stealth Superlight.
Upright Leisure Riders: If you sit in a very upright "commuter" position, a saddle with more curvature and thicker gel padding (like the Ergon SMC) may be more comfortable.
Extreme Narrow Preferences: If you have very narrow sit bones and prefer a traditional long, narrow racing profile, the Sirin’s slightly wider front profile might feel too broad.
The PRO Sirin is unique because it features an integrated accessory mount on the underside of the shell. You can bolt a PRO Camera Mount, Fender, or CO2 Bracket directly to the saddle. This is far more secure than using straps and keeps your bike looking incredibly clean. If you're planning on using this for gravel, we highly recommend the integrated fender to keep your chamois dry without the rattle of traditional clip-ons!
