Assos UMA GT Bib Shorts S11 2026

The UMA GT Bib Shorts S11 are designed to accompany cyclists on all their summer outings, whether regular training sessions, endurance rides or long days in the heat. A true entry-level reference from ASSOS, it benefits from the brand's expertise with a design focused on comfort, stability and breathability.

The S11 generation introduces the new QUARTZ fabric, which is lighter, stronger and more durable, while retaining excellent moisture management. Its wrap-around structure ensures an even fit and a deep black colour that doesn't bleach when stretched. The regularFit cut and slightly extended leg length offer a modern silhouette and greater stability on the thigh.

The shoulder straps feature rollBar technology, derived from the Racing Series, which stabilises the insert during changes of support and keeps the shorts perfectly in place. At the waist, the zeroPressure Waist construction ensures a secure fit without compression or pinching, even over long periods.

The GT S11 insert is based on a 12mm endurance platform, combining vibration absorption and breathability. Perforated 3D Waffle foam promotes air circulation, while goldenGate 2.0 construction naturally follows the pedalling motion to limit friction. The Sundeck Tec finish on the front reduces pressure and improves aerodynamics as well as ventilation.
