Assos Bike

Frequently Asked Questions

• How should I size Assos bib shorts like the S11, Equipe RS, and Mille GT for a race-ready fit?

  Assos runs a performance, body-contouring fit—expect a snug, compressive feel that hugs riding positions. Use Assos’ size chart as your first reference and factor in leg length (S11 comes in standard/short/long options); if you prefer less compression or more all-day comfort, lean toward the Mille GT rather than the S11 or Equipe RS.
• What is the GoldenGate 2.0 chamois and why does it matter for long rides?

  GoldenGate 2.0 is Assos’ updated no‑stitch chamois design that uses high‑density foam, ventilation holes, and side cutaways to reduce friction, improve airflow, and absorb road impacts. The result is reduced chafing and better shock damping over long distances while maintaining close contact with the saddle.
• How does the S11/Equipe RS line compare to the Mille GT or RSR for racing versus endurance riding?

  S11 and Equipe RS are tuned for race performance with aggressive aero shaping, tighter compression, and lighter, more ventilated fabrics aimed at speed and power transfer. Mille GT (and RSR variants) prioritize longer-ride comfort with a slightly more forgiving fit, added cushioning and durability, and fabric choices that favor all‑day ventilation and support. Choose S11/RS for racing or fast efforts and Mille GT for centuries, alpine days, and mixed-terrain endurance.
• Which Assos jersey should I pick for hot-weather racing versus long rides: RS Aero, UMA GT, or MILLE GT SS26?

  RS Aero is the aero‑optimized, close‑fitting option built for speed and minimal drag; UMA GT and MILLE GT SS26 are designed with ventilation and comfort in mind for extended efforts. MILLE GT SS26 offers a more endurance‑oriented cut and features like triple rear pockets and breathable Type.157/Type.112 fabric blends, while RS Aero focuses on raw‑cut sleeves and streamlined panels for race days.
• How do Assos fabrics, compression, and construction manage heat, moisture, and road vibration?

  Assos combines ultra‑light, moisture‑wicking fabrics (e.g., Type.157 and Type.112) with targeted ventilation panels to move sweat away and maintain skin dryness in heat. Graduated compression supports circulation and reduces muscle fatigue, while multi‑panel construction, silicone grippers, and the GoldenGate chamois help keep garments in place and absorb road shock for a smoother ride.
