Key Features

• SPACE Design: 250 mm length × 147 mm width with +5 mm of additional foam compared to the standard Scratch M5 – delivers plush support without compromising power transfer.
• T SHAPE Ergonomics: Unisex geometry suitable for road, gravel, and mountain biking; supports natural pelvic movement across multiple riding positions.
• MSS Multi Sector System: Independently working foam pads, co-developed with the Polytechnic of Milan, adapt to your pedalling motion, absorb vibrations, and reduce fatigue.
• Round Profile: Encourages natural pelvis rotation, improves lumbar stability, and spreads pressure evenly across the saddle surface.
• PAS (Perineal Area System): A central relief channel eliminates pressure peaks, enhances blood flow, and prevents numbness – perfect for long-distance comfort.
• Tirox Rail: Lightweight, durable alloy rail (213 g) keeps overall weight low; the same model is also available with a Nack carbon rail (175 g) for further weight savings.
