As Colnago’s flagship aero road bike crafted for racing cyclists pursuing extreme aerodynamic efficiency, the V4Rs is centered on "minimizing wind resistance and maximizing power output". It integrates cutting-edge aerodynamic design with race-grade stiffness, serving as a "speed weapon" for flat sprints, high-speed cruising, and stage races. While retaining Colnago’s Italian craftsmanship aesthetics, it pushes aerodynamic performance and practical adaptability to new heights through wind tunnel optimization and structural innovation.
Its core advantages include:
- Extreme aerodynamic optimization: After over 500 hours of wind tunnel testing and CFD fluid dynamics simulation, the frame features a "teardrop-shaped truncated head tube + flat rear stays" combination, with a "seamless transition" at the junction of the fork and frame, effectively reducing the drag coefficient (15% improvement compared to the previous V3Rs). The integrated frame design "hides" components such as brakes, cables, and bottle cages within the aerodynamic profile, further reducing airflow interference—saving approximately 8 watts at 40km/h.
- High-modulus carbon fiber & stiffness balance: Utilizing Colnago’s exclusive "HM12K" high-modulus carbon fiber, the frame weighs only 980 grams (excluding the fork) through "directional lamination technology", while torsional stiffness is increased by 12%. The reinforced bottom bracket area ensures lossless transmission of pedaling force; even during high-intensity sprints or climbing efforts, frame deformation is controlled within 0.3mm, providing riders with a "hard-connection" feedback.
- Practical adaptability design: Unlike pure aero models that "sacrifice comfort for speed", the V4Rs’ rear stays adopt a "tapered cross-section" combined with a "flexible groove" on the seat tube, absorbing 30% of road vibrations—balancing high-speed cruising with long-distance riding comfort. It is compatible with 28c wide tires (max 30c), enhancing grip and fault tolerance on complex roads to meet the diverse needs of stage races.
- Speed validation in professional arenas: As the sprint mainstay for top pro teams like Israel-Premier Tech, the V4Rs has helped riders win flat stages in the Tour de France, Giro d’Italia, and other Grand Tours. Its stability in crosswinds (drag increase ≤5% at ±15° wind angles) and short-distance explosive performance (1.2km/h average speed boost in 500m sprints) have been 实战验证 (verified in practice).
- Italian craftsmanship & race-grade details: Each V4Rs undergoes handcrafted carbon fiber lamination and painting at Colnago’s Italian factory. The iconic "quill logo" features 3D embossed craftsmanship, contrasting with matte/gloss gradient paint for visual impact. It comes standard with Colnago’s exclusive "CC.01" integrated stem (adjustable angle ±6°), adapting to different riders’ positions; the "Pro Fit" customization service is available to optimize frame geometry based on riders’ physical data, achieving a "rider-bike unity" handling feel.
