The ASSOS MILLE GTS Bib Shorts S11 Long are long-distance endurance bib shorts engineered to balance aerodynamic performance, supportive compression, and lasting comfort. The S11 generation introduces a less restrictive waist and leg opening, increased vertical stability, and improved cooling airflow throughout the insert.
Butterfly-wrap panelling surrounds the leg muscles with targeted, fatigue-reducing compression, while the rollBar suspension system stabilises the insert during sprints, climbs, and corners. The dual-layer GTS S11 Insert combines a 9mm base with 4mm of targeted support, providing 13mm of shock absorption and vibration damping for long days in the saddle.
Key features
Product specifications
GTS S11 Insert
The dual-layer Shock-Absorb Damping System Twin combines fast-drying, high-density foams to absorb impacts and reduce micro-vibrations. The perforated 3D Waffle construction reduces weight and increases breathability, while kraterCooler and whirlKrater perforations circulate cooling air throughout the insert. The goldenGate 2.0 construction allows the insert to move naturally with the body, reducing friction throughout the pedal stroke.
Composition
Size & fit
The GTS regularFit sits between a pure endurance fit and a second-skin racing fit, combining streamlined aerodynamics with long-distance comfort. This Long version features 3cm of additional leg length compared with the standard model.
Care & washing instructions
Machine wash cold on a gentle cycle with similar colours. Do not bleach, tumble dry, iron, or dry clean. Air dry to preserve the fabric’s elasticity, compression, and insert performance.

The ABR1 Pocket Bib Shorts are made for the longest days on the bike. Albion developed them with ultra-distance riders, and they've been ridden to wins and record times on the Tour Divide, the Atlas Mountain Race and the Highland Trail 550. If your rides are measured in hours rather than kilometres, start here.
Two mesh leg pockets and a rear side-entry pocket let you carry a phone, gels or a wind jacket without touching your jersey pockets. That's handy on gravel and bikepacking trips, and just as useful on a long road day. Everything stays reachable while you ride.
The Albion x Elastic Interface chamois is built for long hours in the saddle. The 2025 update adds a higher gauge main fabric for more compression and polypropylene-knit straps that move moisture away faster. A hidden Rear Guard panel above the pad makes the shorts last longer.
An on-bike fit that runs true to size, with a reduced number of panels and flatlock seams. Our studio model is 180 cm (chest 91 cm, inner leg 80 cm) and wears size S. Want to compare them with your current bibs? Try them on in one of our stores in Amsterdam, Utrecht or Rotterdam.
