Engineered for riders who demand precision, durability, and speed, the SL5 carbon wheelset strikes the perfect balance between aerodynamic efficiency and everyday usability. Featuring a 50mm rim height and a 23mm internal width, the SL5 delivers exceptional tyre support and stability, whether you choose clincher or tubeless setups. Made in high-modulus UD & 3K carbo fibre, the SL5 ensures outstanding stiffness and responsive power transfer, all while maintaining a lightweight profile at just 1390g per pair. Equipped with "Allroad" hubs, steel bearings, and a robust 40-tooth dual-ratchet engagement system, the SL5 guarantees smooth rolling and efficient power transmission.

Wheelset Tubeless rim tape Tubeless valves Centre Lock lockring Freehub ratchets lubricant 23mm Internal Channel The 23C rim is designed to accommodate tyresstarting from 28mm, improving the overall aerodynamics of the wheel-tire system. External nipples simplify maintenance and truing operations, making adjustments quick and accessible. The ABS system prevents loosening of nipples and spokes, ensuring long-lasting stability and reliability. High-Modulus Carbon Rim Made in high-modulus UD and 3K carbon fibre, the SL5 ensures outstanding stiffness and responsive power transfer, all while maintaining a lightweight profile at just 1390g per pair. Allroad Hub Technology With lower flanges, the hub body is more compact and aerodynamic, reducing air resistance and improving pedaling efficiency. The lightweight structure ensures a significant weight reduction without compromising strength. The result is a reliable, smooth-running hub. 40 Tooth Ratchet System The 40-tooth dual ratchet system halves the engagement angle compared to the previous generation, providing an immediate response to pedaling. The cylindrical spring ensures greater stability and consistent operation of the mechanism. RFID Technology Originality verification and warranty activation. An RFID tag connected to a smartphone app provides to the customers the authenticity of their purchase and ensures they can easily access warranty services. RFID tag (Radio Frequency Identification) is a small chip containing information about a product, allowing it to be digitally and uniquely identified. This allows the consumer to verify that the wheelset they are buying is original.
