A New Dimension In Comfort & Performance

Introducing the Prologo Dimension 143 Saddle, outfitted with a short nose design and a pressure-relieving cutout, along with a wider seating area to distribute weight.

The name Dimension contains the importance of the project itself: to create an innovative product in terms of size, design, and ergonomic shape suitable for all disciplines and perfect for men and women. Dimension is comfort, performance, and lightness.

The combination of a short nose (35mm less than a traditional saddle) and the PAS system ensures blood flow and pressure relief, guaranteeing comfort even in an aerodynamic position or during the maximum pushing phase.

The wider seating area (width 143mm) allows a better distribution of body weight. The Dimension saddle has been tested and developed in collaboration with the best international professional teams to ensure a saddle suitable for all users.

  • Cut-out for pressure relief
  • Wider sitting area for increased weight distribution
  • Size: 245x143mm
  • Weight with Nack (Carbon) rail: 150gr
  • Weight with Tirox (Alloy) rail: 180gr
