Selle Italia SLR Boost 3D Ti 316 Superflow

3D-Printed Cushioning. Titanium Compliance.

The breakthrough of the Selle Italia SLR Boost 3D Ti316 Superflow lies in its DLS™ (Digital Light Synthesis) 3D-printed cover. Utilizing Carbon® 3D printing technology, the saddle features specialized, progressive damping zones. Instead of uniform foam density, the lattice structure provides firmer support under your sit bones for maximum power transfer, while softening in high-pressure areas to eliminate soft-tissue discomfort—delivering custom-like comfort straight out of the box.

Why the SLR Boost 3D Ti316 is a Performance Benchmark:

• Progressive 3D-Printed Lattice Matrix: Engineered with variable density zones that offer targeted support and cushioning exactly where you need it, significantly reducing pressure points on long, high-intensity rides.

• Ti316 Titanium Rails (7mm Round): Formulated to be 25% stronger and 15% lighter than standard hollow titanium rails, providing exceptional fatigue resistance and soaking up high-frequency road vibrations.

• Massive Superflow Relief Cutout: The generous central channel completely eliminates perineal pressure and numbness, maintaining optimal blood flow during aggressive aero efforts in the drops.

• Boost Short-Nose Profile: Measuring a compact 248mm in length, the shortened nose reduces inner-thigh friction and makes it easier to lock into an aggressive, powerful riding stance.

• Universal 7mm Rail Standard: Round titanium rails fit virtually any standard seatpost clamp without requiring specialized 7x9mm oval-rail adapters.

The Alegro Perspective: 3D-printed saddles have completely changed the game for riders who struggle with saddle sores or chronic numbness on long rides. Traditional foam compresses and breaks down over time, but this 3D lattice maintains its supportive spring indefinitely while allowing incredible breathability and airflow. Pairing this high-tech upper with Ti316 titanium rails gives you the perfect combination of structural compliance and durability without the delicate setup worries of carbon rails.
