Advanced Carbon Rails
Developed with a new carbon lay-up method, the carbon rails deliver exceptional lightness and durability. The optimized rail angle improves vibration absorption, ensuring comfort even on long rides, without sacrificing stiffness or power transfer.

Handmade, Lightweight Pad Covering
A handcrafted, premium-quality cover adds both style and functionality. The minimal padding is applied only where needed, reducing unnecessary weight and maintaining the classic SLR performance feel.

Neutral Shape
The neutral anatomical shape provides balanced support for riders with both anterior pelvic rotation (dynamic riders) and posterior pelvic rotation (static riders). It ensures optimal comfort and stability across a wide range of riding positions.

Carbon Powered
Constructed with a carbon composite shell reinforced by high-grade nylon polymer, this saddle strikes the perfect balance between stiffness and flexibility — ideal for high-performance road cycling.

With its 130 mm width and 242 mm length, it suits riders with a narrower pelvis who seek efficient power transfer and stable positioning.
