Assos Women's UMA GT Spring Fall Cycling Bib Tights S11

The Assos Women's UMA GT Spring Fall Bib Tights S11 are a midweight endurance tight built for riding in the 53–68°F range, where a summer bib is too thin and a winter tight is too much. What sets them apart is POLAR, a new Assos textile with a brushed inner face and 50% pre-consumer recycled content — a material developed specifically for the GT S11 and tested to deliver thermoregulation, breathability, and stretch without compromise. At 234g, they sit comfortably in carry-on range for travel riding.

The bib construction is borrowed from Assos's Racing Series: an external rollBar strap that locks the bib in place without pressure points, adapted here for the GT's endurance-tuned fit. The insert is the rider-favorite UMA pad upgraded with a Sundeck pressure-relief panel — a trickledown from the RS lineup that targets long-saddle-time hot spots. The result is a tight that covers shoulder-season riding without feeling like a seasonal compromise.

Who It's For

• Road and gravel riders logging 3–5+ hour efforts in spring or fall conditions
• Riders who find summer bibs inadequate below 60°F but dislike the bulk of full winter tights
• Endurance cyclists who prioritize all-day insert comfort over race-day aero properties
• Riders who want PFAS-free, OEKO-TEX certified kit without sacrificing fit or function

Riders doing primarily cold-weather riding (below 50°F) or those who need windproofing on exposed descents should look at a heavier insulation tier — the GT S11 rates 1/5 on windproofing.

What to Look For

• Temperature window: The GT S11 is calibrated for 53.6–68°F. If your target rides frequently dip below that, consider a warmer option; if they're mostly above it, the tight may feel heavy mid-ride.
• Insert fit: The UMA insert with Sundeck panel is designed for regular fit geometry. Riders who have found other Assos inserts too firm in specific contact zones should note the Sundeck panel addresses that directly.
• Sustainability tradeoffs: POLAR uses pre-consumer recycled inputs and is PFAS-free — for riders who weight this in purchasing decisions, it's worth knowing the material was performance-validated, not just green-badged.

Key Features

POLAR Fabric. The main fabric (86% Polyamide, 14% Elastane) uses a brushed inner face for warmth-to-weight efficiency in the shoulder-season range. Half the material comes from pre-consumer recycled sources, and it carries OEKO-TEX certification with no PFAS treatments. Assos tested it against their standard performance benchmarks before releasing it — breathability rates 4/5, insulation 3/5.

External rollBar Bib Strap. Adapted from the Racing Series, this construction routes the bib strap externally to eliminate pressure on the lower back and core. It maintains position across varied riding positions — useful on long climbs, gravel, or any ride with frequent position changes.

UMA GT S11 Insert with Sundeck Panel. The 12mm UMA insert is the endurance-spec pad in the Assos lineup. The GT S11 version adds a Sundeck panel — a softer, pressure-redistributing layer at key contact points — borrowed from the RS product range. Designed specifically for rides where insert fatigue accumulates over hours.

Rider Intent Summary

• Biggest strengths: Calibrated thermoregulation for the 53–68°F window; long-ride insert comfort via the Sundeck panel; lightweight at 234g with sustainable fabric credentials
• Tradeoffs: Minimal wind and water resistance (1/5 each) — not suited for exposed or wet conditions; racing-specific aero properties are secondary to endurance comfort
• What makes it different: POLAR textile is unique to this garment — a new Assos-developed fabric that balances recycled content with verified thermal and stretch performance, paired with Racing Series bib architecture in an endurance platform

Victory's Take

At Victory Bicycle Studio, we reach for the GT S11 when customers ask what to wear between their summer kit and their winter tights — it's a specific problem this tight solves well, and the Sundeck insert upgrade makes a real difference on longer days in the saddle.
