The medium weight Assos TK.434 is the perfect bib knicker for transitional and chilly weather. Based on the time-tested fit of the classic 607, the knicker is refined with thirteen articulated panels for a free-motion fit in the cycling position. Assos Type A.434 compression spandex fabric on the main panels supports your muscles, increasing performance and delaying fatigue. Specific "kneezone" panels remove pressure points and rotational friction, while soft-brushed RXQ kneecap panels keep your knees warm and comfortable. The FI. Mille S5 insert ensures total comfort in the saddle.

ASSOS FI. Mille S5 Insert

  • Elasticity ensures a contoured, anatomic fit that follows your cycling movement
  • Innovative ergonomic cut for less pressure on sensitive areas
  • Insert stabilizer with indented memory foam for long distance comfort
  • Breathable microfiber surface for superior moisture management

The Assos tK.607 FI.Mille_S5 bib knicker is built with a combination of Roubaix and Roubaix Quantum Leap (RXQ) fabrics. RXQ is a breathable, soft touch insulating fabric featuring a unique 3D air-channel texture. Air is a great insulator, and wrapping your body with this structured fabric creates a micro air cushion next to your skin, enhancing warmth and allowing moisture to evacuate. Tailored to fit your body in the cycling position, the Assos Campionissimo AEPD racing fit offers total freedom of movement, and features strategically placed seamless panels behind the knees for a smooth, unimpeded rotation. A stretchy, anti-static mesh back panel between the bib straps improves ventilation and enhances the fit. Comfy FI.Mille_S5 insert is anatomically formed and cushions sensitive areas, eliminating performance-robbing friction. Silicone grippers below the knees secure the fit.
