The Skycarb is Astute’s top of the line saddle pulling together more than 40 years of Italian saddle crafting experience to create something entirely new. Ultra-thin carbon rails link up to the SPAS, shock absorber system, vastly reducing road harshness and bumps. Two ultra-thin, full carbon base layers form the foundation for the same triple density padding and memory foam found in all three of Astute’s saddle designs. Total weight is only 145 grams. The Skycarb comes in both SR, traditional and VT, cut-out versions.
