Assos MILLE GTO Bib Shorts S11 long - Black Series

The MILLE GTO Bib Shorts S11 long are Assos' endurance-oriented offering created to maximise comfort on multi-hour rides. Built around the plush GTO insert, these bibs prioritise pressure distribution and ventilation so you can stay in the saddle longer without transferring discomfort to your hips and sit bones. The long leg cut provides additional coverage for riders who prefer a slightly longer inseam.

Construction focuses on a balance of support and freedom of movement. Fabrics are selected to reduce bulk where it is not needed and add structure where it improves fit. The leg hem uses Assos' infused frictionless gripper, engineered to hold the shorts in place without pinching or creating hot spots, so the shorts stay settled through pedalling and weight shifts. Breathable panels and the pad design work together to manage heat and moisture on long efforts.

Fit is tuned for endurance riding rather than race compression. The bib straps are adapted from Assos Racing sequences to provide reliable hold without digging into the shoulders, while the patterning across the thighs and hips aims to avoid constriction when your position changes. Together, the materials and construction reduce friction and rubbing, helping minimise chafing over long distances.
