Assos Mille GT Indoor Bib Shorts S11 - Womens Info

The Assos Mille GT Indoor Bib Shorts S11 - Womens are built for a specific job: long sessions on a trainer, where heat and pressure build up faster than on the road. Without outdoor airflow, the fabric and the chamois carry more of the load, and these shorts are set up for that. They are a women's-specific bib short from Assos, the Swiss brand that has been making cycling apparel since the 1970s.

The main fabric is Assos's POLSTAR, described by the brand as designed to maximize airflow while staying soft against the skin. The legs combine QUARTZ fabric with open-structure POLSTAR panels placed in areas that need ventilation, balancing durability where the shorts see friction with lighter, cooler fabric elsewhere. On a trainer, where you sit in the same position for an hour or more with no cooling breeze, that ventilation matters.

The chamois

The GT S11 chamois is a 12mm-thick, shock-absorbing insert made from compressive foam layers, shaped by thermoforming to reduce edges that can irritate on long rides. In front, a Sundeck section adds airflow where cushioning is not needed. Trainer riding puts steady pressure on the saddle contact points instead of the varied loading you get on the road, so a supportive, well-shaped pad is worth having on indoor sessions.

Fit and construction

The bib straps keep the shorts securely in place and are designed to promote ventilation, so there is no waistband pressing on the abdomen when you are tucked over the bars. The fit is women's specific. Sizing runs from XS through XL and XXL, and Assos sizes its women's shorts by hip measurement, from 80-86cm (31.5-33.8") for XS to 108-114cm (41.2-44.9") for XL, so check your hip size against the chart before ordering. The colorway is Blackseries.

At $210, the Mille GT Indoor is priced for riders who spend many hours on a trainer through the winter, or who train indoors year round, and want apparel built for that use instead of using their road shorts. They fit best for structured indoor training, virtual group rides, and long endurance sessions.

The RA Perspective

Indoor riding is hard on shorts. There is no wind to cool you, you sit still in one position, and you sweat far more than on the road. These shorts are designed around that, and the ventilated fabric is the reason to consider them over a regular road short.

The GT S11 chamois is the more supportive of Assos's pad options, and a 12mm pad is a good match for long trainer sessions where the same pressure points take the load for an hour or more. Riders who prefer minimal padding may find it more than they need, particularly for shorter sessions.

Fit is the most important thing to get right. Assos sizes women's shorts by hip measurement, so check the chart before you order instead of ordering your usual size. The bib straps are made to keep the shorts in place without creating pressure at the waist.

If you spend a lot of the winter on a trainer, these are the shorts we would put on for structured workouts and long endurance sessions. For outdoor riding you would be better served by the standard Mille GT.
