Wide Race Saddle with PAS Comfort & Nack Rail

Overview

The Prologo Dimension R2 Nack 153 Saddle is the wide, high-performance evolution of one of the most popular saddles in the Dimension family. Designed for professionals and demanding amateurs, it delivers top-tier performance across road, gravel and XC/Marathon mountain biking.

Compact Shape With 153mm Support: With compact dimensions of 245x153mm, this version offers a wider seat for improved stability and comfort. It’s ideal for riders with wider hips or those who need better weight distribution during long, intense efforts.

Lightest Dimension 153 Ever: Through continuous refinement in materials and design, Prologo has created the lightest Dimension 153 to date, weighing just 165 grams. It combines minimal weight with race-level performance and durability.

Optimized EVA Padding & Comfort: The updated EVA foam allows reduced padding thickness in the rear section while maintaining full support. With 2mm more foam than the standard version, it enhances comfort without adding unnecessary weight.

Nack Rail For Maximum Rigidity: The Nack rail is constructed from Nano Carbon Fiber, blending carbon fiber, Kevlar and aluminum filaments. This advanced composition ensures exceptional stiffness and ultra-light performance.

Long-Fiber Carbon Base Structure: The base is made from long-fiber carbon, delivering an excellent balance of stiffness, strength and comfort. It supports efficient power transfer while maintaining structural reliability under high loads.

The Prologo Dimension R2 Nack 153 Saddle delivers lightweight efficiency, wider support and pro-level performance for riders who demand the best from every ride.
