Assos UMA GT Bib Shorts S11 EF Replica 2026

The UMA GT Bib Shorts S11 EF Replica 2026 are endurance bib shorts engineered for daily training rides and long-distance adventures. Assos shapes these shorts around a regularFit silhouette and lightweight QUARTZ textiles to reduce seam bulk and skin friction, so you can layer comfortably and ride for hours without hotspots. The EF Replica graphics add a racing-inspired aesthetic while the construction focuses squarely on comfort and durability.

Comfort on long rides is delivered by the GT S11 insert, a 12mm compressive foam platform specifically tuned for endurance use. Thermoformed shaping and the 3D Waffle perforated layer increase breathability and reduce weight, while the goldenGate 2.0 free-floating construction allows the pad to move with your body rather than against it. Together these insert technologies lower pressure points and help maintain saddle comfort over extended efforts and mixed terrain.

Fit and stability are handled with Assos engineering adapted from their Racing Series. The rollBar stabilises the insert to prevent unwanted shifting as you climb, sprint or ride out of the saddle. The PILtec microdot-treated leg band gives a secure hold at the hem without heavy silicone, keeping the shorts in place in wet or dry conditions. Around the waist, the zeroPressure construction provides a soft, elastic hold that removes pinching yet retains effective support for a clean, comfortable fit.

Materials are chosen for breathability and longevity. The QUARTZ body textile is a lightweight warp knit with permanent odour control and a true black that resists showing white as it stretches. High quick-dry ratings and strong breathability mean these shorts perform where heat and sweat accumulate, making them well suited to warm-weather training and multi-hour rides.
