The aerodynamic structure has been optimized by Nova Ride through software and wind-tunnel testing. Months of development and feedback have allowed us to create the most efficient product to date. Its straightforward design reflects the priority: efficiency above all. Reduction of aerodynamic drag with particular attention to optimizing frontal impact, as well as attenuation and control of tailwind thanks to its exclusive airfoil design (front and rear closed). The added material over the standard version, without increasing weight, required optimizing the thickness of our ultralight 3K carbon fiber plates by 33% in key areas, without compromising durability. \u003c\/p\u003e\n\n\u003cul\u003e\u003cli\u003eWe recommend a cassette with a maximum of 34 teeth for optimal adjustment and shifting. \u003c\/li\u003e\u003cli\u003eFor optimal performance, replace the chain. \u003c\/li\u003e\u003cli\u003eWe strongly recommend adding 2 to 4 additional links. \u003c\/li\u003e\u003cli\u003eCompatibility Ultegra RD-8150 and Dura-Ace RD-9250, 12-speed.
