Innovation. High technology. Italian craftsmanship. Unique design. The Sun collection is the latest project developed by Astute Labs to provide the highest level of safety, comfort and performance for the most demanding riders. Flat design for on-road endurance riding and long training sessions.

SUN LINE SR features dedicated dimensions - with a width of 145mm instead of the traditional 135mm - and is designed to provide higher comfort and performance for riders with larger sit bones. The inner shell is made of 15% carbon-fibre reinforced nylon, while the outer shell is made of nylon. An innovative construction enhances the saddle's look while maintaining a clean silhouette and improving performance, as it significantly increases the padding space while preserving the same volume and, as a result, reduces pressures in the perineal area and ensures ultimate comfort.

Black painted titanium rail with tubular Titan-V Technology - 80% titanium and 20% vanadium. Lightweight, durable and anti-vibration for full comfort and reliability.

The SR seat (from "sarà, meaning "closed in Venetian dialect) has been designed to make the most of the «tension arc» formed by the twin shell construction and the carbon rail. While pedalling, the body rests on the entire surface of the saddle,which results in ultimate comfort and better performance.

Features Memory Foam padding to provide better comfort in the perineal area - firmer in the back to support the sit bones, and softer on the front.

SUN LINE SR is protected by three international patents and is exclusively handmade in Italy according to strict local regulations.
