Description

Endurance bib shorts for daily cycling and long-distance adventures, engineered with frictionless support, a plush insert, and the EF Pro Cycling Team’s 2026 racing graphics.
EF Pro Cycling’s official kits are called WE RIDE IN PEACE, and we brought those aspirational graphics to our GT S11 model – foundational equipment for daily rides and long-distance training. The EP Pro Cycling version of the GT S11 is the product of years of refinement, and it showcases the iconic comfort, fit, and durability that makes ASSOS what it is. The new body textile is lighter, more durable, and has a deeper, true-black color while maintaining breathability. The fit is further refined with the X-Frame suspension system and a stabilizing rollBar construction – technology adapted from the Racing Series.
Specifications:
– Main Fabric: 84% PA, 16% EA

Technology:
Featured Fabrics:
– The new QUARTZ textile is a lightweight, breathable warp knit with permanent odor Control. The true-black color doesn’t turn white or become transparent while stretching during normal use, and 80% of its content is from pre-consumer recycled polyamide.
Construction/Fit:
– Our streamlined regular Fit and body-contoured shaping reduce seams, eliminating friction for total comfort and easy layering.
Engineering:
– Roll Bar: A patented bracing design adapted from the Racing Series. Stabilizes the insert and locks it in place as your weight transfers while sprinting, climbing, and cornering.
Engineering:
– PILtec Plug-In: A lightweight, ultra breathable textile band across the leg opening. The microdot silicone treatment is invisible from the outside but stabilizes fit and maintains grip in wet or dry conditions.
Engineering:
– Zero Pressure Waist: A soft, highly elastic waist construction that improves comfort and hold at the waist, minus any pressure or pinching.
GT S11 Insert:
– Shock-Absorb Damping Mono 12: Compressive foam layers in a 12mm endurance platform. Thermoformed shaping reduces ridges and irritation.
GT S11 Insert:
– 3D Waffle: A patented, three-layer, perforated foam that increases breathability and eliminates excess weight.
GT S11 Insert:
– Golden Gate 2.0: A free-floating construction that moves with your body rather than against it. New cut-outs on the wings reduce friction throughout the pedal stroke.
