    ASSOS UMA GT Bib Shorts S11 — Women’s Endurance Bib Shorts, Redefined

    The UMA GT has long been ASSOS’s core endurance bib short for women — the garment that defines what the brand stands for. The S11 generation doesn’t reinvent that formula, it sharpens it. A lighter, more durable body fabric. Bib strap technology adapted from the Racing Series. A more breathable insert. The result is women’s cycling bib shorts that feel as good on hour six as they do on hour one.

    QUARTZ Fabric — Lighter, Darker, Better

    The S11 body is built from the new QUARTZ textile — a lightweight, breathable warp knit with permanent odour control. It’s lighter and more durable than its predecessor, and delivers a deeper true-black colour that stays opaque under stretch. 80% of its content comes from pre-consumer recycled polyamide.

    rollBar Bib Straps

    Adapted directly from the ASSOS Racing Series, rollBar is a patented bib strap bracing system designed to stabilise the insert and keep it locked in position as your weight transfers through sprinting, climbing and cornering. No shifting, no bunching — just consistent support from start to finish.

    zeroPressure Waist

    A soft, highly elastic waist construction delivers a secure hold without any pressure or pinching. It sits comfortably through long efforts and holds its position without relying on rigid banding.

    PILtec Plug-In Leg Openings

    At each leg opening, a lightweight, ultrabreathable textile band features an invisible microdot silicone treatment that maintains grip and fit in both wet and dry conditions — without the bulk or discomfort of traditional silicone grippers.

    GT S11 Insert — 12mm Endurance Platform

    The updated GT S11 insert is built around a 12mm compressive foam platform and features four key technologies working together:

    Shock-Absorb Damping Mono 12 — thermoformed compressive foam layers that reduce ridges and pressure points across long rides.

    3D Waffle — a patented three-layer perforated foam construction that increases breathability and eliminates unnecessary weight.

    goldenGate 2.0 — a free-floating construction that moves with the body rather than against it. Updated wing cut-outs reduce friction throughout the pedal stroke.

    Sundeck Tec — an ultrasoft front panel that minimises the insert’s footprint, eliminates pressure and increases airflow at the front of the chamois.

    regularFit Construction

    ASSOS’s streamlined regularFit uses body-contoured shaping and a reduced seam count to eliminate friction and simplify layering — a clean, precise fit that works across a wide range of body shapes without compromise.

FAQ

Questions and answers relating to Assos UMA GT Bib Shorts S11

What is the ASSOS UMA GT Bib Shorts S11 designed for?

Answer

The UMA GT Bib Shorts S11 are designed for women’s endurance road cycling — long days in the saddle where sustained comfort, breathability and a secure fit matter most. They’re rated for temperatures of +21°C and above.

What is the GT S11 insert?

Answer

The GT S11 is a 12mm endurance chamois featuring four technologies: Shock-Absorb Damping Mono 12 thermoformed foam, 3D Waffle perforated breathable layers, goldenGate 2.0 free-floating construction, and Sundeck Tec front panel. Together they deliver all-day padding performance with improved breathability over previous generations.

What is rollBar technology on the UMA GT S11?

Answer

rollBar is a patented bib strap bracing system adapted from the ASSOS Racing Series. It stabilises the insert and keeps it locked in position as your weight shifts during climbing, sprinting and cornering — preventing the insert from moving out of place on long rides.

How do the ASSOS UMA GT Bib Shorts S11 fit?

Answer

The UMA GT S11 uses ASSOS’s regularFit — a body-contoured, streamlined cut with a reduced seam count. It’s designed to fit a wide range of body shapes comfortably without the aggressive compression of a race fit. Refer to the ASSOS size guide for measurements.

What is the QUARTZ fabric used in the UMA GT S11?

Answer

QUARTZ is a lightweight warp-knit fabric with permanent odour control and a true-black colour that stays opaque under stretch. It’s more durable and lighter than previous UMA GT fabrics, with 80% of its content from pre-consumer recycled polyamide.
