The Skylite fills out the middle of Astute’s range. The design is nearly identical to Skyline model, but the titanium rails have been substituted for carbon shedding almost 40 grams. Joining the rails to the saddle base is Astute’s SPAS, or Shock Pad Absorber System which takes out some of the road buzz and bumps. The Skylite gets the same triple padding and memory foam as the Skyline. Total weight comes in at 165 grams. The Skylite comes in both SR, traditional and VT, cut-out versions.
