Product Description

The Assos GTO S11 Bib Shorts are the most luxurious endurance bib shorts in the Assos collection, engineered for exceptional comfort on the longest rides. Every component has been selected to minimise pressure points while delivering outstanding support, making them ideal for riders spending long hours in the saddle.

Soft yet supportive fabrics contour naturally to the body, while the flagship S11 insert offers premium cushioning and reduced friction over extended distances. The refined construction creates a smooth, unrestricted fit that remains comfortable throughout demanding endurance rides.

Who is it for? The GTO S11 is designed for endurance cyclists, gran fondo riders and anyone seeking maximum comfort without compromising performance. The fit is close and supportive but less aggressive than the Equipe raceFit, making it suitable for long-distance riding where comfort is the priority.

FEATURED FABRICS - The primary textile, OSSIDIA, strikes the ideal balance between frictionless comfort and muscle-supporting compression. Its warp-knit construction incorporates ultrathin elastic yarns for gentle, fatigue-reducing compression and body-mapping elasticity that wraps your large muscle groups in silky-smooth comfort. An insert of LOSANGA on the crotch panel eliminates pressure and increases cooling airflow.

CONSTRUCTION/FIT The Assos GTO bib uses regularFit, engineered for total comfort on the longest rides. The GTO model is upgraded with cranKio Tec, targeted shaping on the hip that eliminates bunching during the pedal stroke.

rollBar: A patented bracing design adapted from the Racing Series. Stabilises the insert and locks it in place as your weight transfers while sprinting, climbing, and cornering.

INject leggripper: Silicone grip infused through the back of the raw-cut leg opening, reducing friction and protecting the grip from sun or sweat damage while maintaining secure hold.

cranKio Tec: Reduces wrinkling across the front of the hips during the pedal stroke to eliminate movement and friction between the textile and the rider.

zeroPressure Waist: A soft, highly elastic waist construction that improves comfort and hold at the waist, minus any pressure or pinching.

GTO S11 Insert - Shock-Absorb Damping System Twin: A dual-layer, 21mm construction with additional support beneath the ischial bones.

goldenGate 2.0: The insert is attached at front and rear, letting it float to move with your body rather than against it. New cut-outs on the sides reduce volume and friction throughout the pedal stroke.

kraterCooler: Perforations in the insert’s leading edge draw intercooling air to maintain breathability and a dry, cool microclimate.

whirlKrater: Perforations strategically distributed throughout the insert, creating a whirlwind of cooling airflow instead of just a unidirectional breeze.

  • OSSIDIA warp-knit textile wraps large muscle groups in silky-smooth, supportive compression
  • GTO S11 insert features a plush, dual-layer 21mm memory foam pad for industry-leading vibration absorption
  • goldenGate 2.0 free-floating insert construction stays in perfect contact with the body to eliminate friction
  • kraterCooler and whirlKrater perforations draw cooling airflow across the pad to reduce humidity
  • zeroPressure waist design delivers a soft, highly elastic, and pinch-free hold across the abdomen
  • Raw-cut hems and subtle, effective leg grippers ensure seamless transitions and a reliable grip
  • Fabric provides built-in odorControl properties and UPF 50+ UV protection

ASSOS bib shorts are engineered with different riding styles in mind, so choosing the correct range can help improve comfort, performance, and fit from your very first ride.

EQUIPE R & EQUIPE RS
The EQUIPE range is designed for performance road riding, fast training, and racing. These bib shorts feature a close-fitting, compressive “second-skin” race fit intended to reduce movement, improve aerodynamics, and deliver maximum stability when riding in an aggressive position on the bike.

MILLE GT & MILLE GTS
The MILLE range is built for endurance riding and all-day comfort. Compared to EQUIPE, the fit is standard with additional comfort-focused features designed for longer rides and a less aggressive riding position.

TACTICA
The TACTICA range is developed for gravel, adventure, and off-road riding the fit is standard and similar to the Mille. These bib shorts balance long-distance comfort, durability, and stability for mixed terrain and extended days in the saddle.

Important Fit Advice
ASSOS bib shorts are anatomically designed to fit best while in the riding position, not when standing upright. When trying them on at home, the shoulder straps may feel firm and the insert (pad) may feel slightly higher or more noticeable than regular shorts. This is completely normal and is intentional within the ASSOS design philosophy.

Once seated on the bike, the bib straps relax into position and the insert is designed to sit flat against the body to eliminate movement, friction, and discomfort while riding.

For the best fit, the bib shorts should feel supportive and secure without excessive looseness, bunching, or fabric movement when in a riding position.
