Assos EQUIPE RS Spring Fall Bib Shorts S9

It happens when we least expect it: The sting of cold air on our thighs, crotch, and glutes cuts into us on the road, distracting us from the race at hand. It marks the beginning of when our summer bibs are no longer warm enough, but we’re not quite ready to reach for our knickers. Enter the Assos EQUIPE RS Spring Fall Bib Shorts S9—tuned for cool fall and spring racing conditions where shorts are still in order, but now with a dose of thigh-warming comfort and protection.

Based on the Assos EQUIPE RS S9, these shorts include our A-Lock Engineering framework to brace the shorts and ensure they remain stabilized in the toughest racing environments. The shorts’ thigh panels are constructed with our brushed-back Osmos Heavy textile, which adds to this stable platform. This is the latest member to join our brushed family of fabrics, and its technical two-in-one composition provides us with several advantages.

The first is that the brushed interior is highly insulating, breathable, and super soft against our skin. The warp-knit outer acts as the “shell” of the shorts, further supporting your leg muscles with its compressive structure. Together, these two components of the textile create a nice compressive hold on our legs, encouraging positive circulation and uniform warmth throughout. Knowing that the wind-facing front panel takes the brunt of the elements, we applied our Sphere Ultra textile in our double-layer twinDeck construction to lock out the icy cold air around the crotch, while still remaining breathable.

For the insert, we incorporated the race-proven EQUIPE RS Insert—minus the kraterCooler ventilation holes—in our signature basalt colorway, equipped with superAir microShock foam, 3D waffle topsheet, along with the ASSOS-exclusive goldenGate technology and horizontal stabilizer in the rear.

Features of the Assos EQUIPE RS Spring/Fall Bib Shorts S9:

• OSMOS heavy is the warmest insulator of Assos EQUIPE RS line. Its combination of aggressive warmth and breathability are paired with a soft inner face and a gently compressive stretch, making it the ideal body material. A panel of 2L Sphere Ultra adds the protection of a weatherproof, breathable membrane at the crotch.
• A-Lock Engineering is Assos S9 racingFit realized for bib shorts, with every fabric panel, strap, and stitch engineered for stability and confident comfort. ASSOS shorts are legendary; this fit design is why.
• A double layer of insulation and weatherproofing preserves your core’s microclimate—a warm, dry engine is key to cold-weather performance.
• Butterfly Pattern:The main textile panel wraps the lower back and legs, reducing seams and providing a more uniform compression across the shorts’ body.
• Carbon Xbib: An A-frame bib that limits vertical stretch in the rear, ensuring a confident fit and stabilizing the chamois and main body panel.
• EQUIPE RS Insert (NO KRATER): Antibacterial microfiber booster top sheet in 3D basalt colorway. Pays homage to the lava stone that gives us strength, stability, and courage.
• goldenGate: A stitching pattern that anchors the front and back but lets the insert’s body float, allowing the chamois to move with your body rather than against it.
• superAir microShock foam: A light, shock-absorbing foam that springs back to its original shape, filling the gaps that open and close between body and chamois during the pedal stroke.
