Prologo Scratch M5 Space Nack 147 Saddle

The Prologo Scratch M5 Space Nack 147 Saddle is the wider, more padded evolution of the iconic Scratch platform. Designed for riders who demand both comfort and high performance, it blends advanced ergonomics with race-ready construction.

Compact Dimensions With Lightweight Build: Measuring 250 x 147 mm, this unisex saddle suits road, gravel, cross-country and marathon MTB riding. Despite its wider support, the Nack version weighs just 173 grams, delivering lightweight efficiency without compromise.

Rounded Shape For Lumbar Stability: The rounded anatomical profile offers enhanced lumbar support and promotes a stable seated position. It is especially beneficial for riders with limited pelvic mobility who require consistent support over long distances.

Space Version With Extra Padding: The Space variant features a wider seating area and additional padding for improved comfort. This design enhances weight distribution and reduces fatigue during extended rides.

MSS Multi Sector System: The MSS seating system divides the saddle into mapped foam zones that function independently. Developed in collaboration with the Polytechnic University of Milan, it improves comfort and pedaling efficiency throughout the stroke.

Nack Rail & Carbon Base Construction: The Nack rail, made from nano carbon fiber blended with Kevlar and aluminum filaments, provides maximum rigidity with minimal weight. The long-fiber carbon base ensures an excellent balance of stiffness and comfort.

The Prologo Scratch M5 Space Nack 147 Saddle delivers wider support, lightweight strength and versatile performance for cyclists pushing hard across disciplines.
