Prologo Scratch 3D Saddle

The Prologo Scratch 3D 147 Saddle combines anatomically mapped 3D-printed padding with a wider, round seating profile for support and comfort across multiple cycling disciplines. Its 147 mm width accommodates riders with wider sit bone spacing, while the T-shape allows freedom to change position along the saddle.

The round profile provides additional lumbar support, helping riders maintain a stable position even with limited pelvic mobility. Three independently mapped zones on each side offer different densities and elasticity, while an additional 3 mm of padding compared with the 140 mm version improves cushioning and weight distribution. A central PAS channel helps relieve perineal pressure.

FEATURES

• Aerodynamic Development: Refined through CFD simulations and wind-tunnel testing of the saddle, bike and rider together.
• Integrated Carbon Plate: A wide, flat mounting structure replaces conventional round or oval rails for a stiff connection between rider and seatpost.
• Airflow-Shielding Side Wings: Conceal the mounting structure and seatpost clamp to reduce their exposure to frontal airflow.
• Tapered Rear Profile: Designed to direct airflow from behind the rider parallel to the road and reduce drag.
• Narrow Racing Shape: The 110 mm width supports pelvic rotation and an aerodynamic riding position.
• Enhanced EVA Padding: Provides cushioning and support across the compact seating surface.
• PAS Pressure Relief: A wide central channel extends along the full contact area to help reduce soft-tissue pressure peaks.
• Lightweight Construction: Claimed saddle weight of just 132 g.
• Modular Design: Separable plate and base facilitate component replacement, repair and end-of-life recycling.
• Dedicated Mounting Clamp: Supplied with a 3D-printed titanium clamp for compatible seatposts.
