The Riel 05 is engineered for maximum aerodynamic performance without sacrificing comfort. Its UPF 30+ micromesh panels on the front, back, and underarms ensure breathability while maintaining a sleek, low-drag profile. Longer sleeves and legs, finished with raw cuts and internal grip, create a smooth, compressive fit that reduces turbulence and prevents fabric shifting. Ribbed aero fabric on the sleeves further cuts drag by optimizing airflow in critical zones, while an external grip in the groin area stabilizes your bike position for efficient power transfer. Developed with pro Marten Van Riel, the Riel 05 blends cutting-edge aero technology and race-ready practicality to keep you fast from start to finish.Real-world gains*:• Up to 15 watts saved• Approx. 1 km/h increase in speed • Up to 2 minutes faster over 80 km*Disclaimer: Performance gains are based on controlled wind tunnel testing and may vary depending on rider position, environmental conditions, and individual physiology.
