FSA KFX i28 Boost wheelset - Black

FSA proudly presents the all-new KFX i28 carbon wheelset, the latest addition to the acclaimed KFX range. Designed in collaboration with elite cyclists, these wheels are built to excel in the toughest Cross Country (XC), Cross Country Olympic (XCO) and Marathon competitions. At the heart of this wheelset is the TOTAL CONTROL concept, which offers exceptional stability, responsiveness and precision no matter where the ride takes you. Even before the official launch, the KFX i28 prototypes have already demonstrated their potential, winning the XC world championship with Alan Hatherly of the Cannondale Factory Racing team. The KFX i28 is a product of FSA's commitment to excellence, combining cutting-edge engineering and meticulous craftsmanship. Made entirely in-house, including carbon production, each wheel is hand-assembled by our skilled craftsmen. This ensures that every component is fine-tuned for maximum performance, durability and precision. FSA's close collaboration with world-class athletes has been instrumental in the development of the KFX i28. Teams like Cannondale Factory Racing have played a key role in testing and perfecting these wheels. Their feedback from top-level competition allowed FSA to fine-tune the wheel set for optimal performance, ensuring that it meets the rigorous demands of the sport at the highest level. 28 mm inner rim width: the KFX i28 features a 28 mm inner rim width, meticulously optimized through field and lab testing. This width achieves the perfect balance between light weight and handling, allowing for better tire grip and better grip on various terrains. This rim improves overall stability and traction, which are critical for maintaining control during dynamic riding conditions. Variable rim height of 22-24 mm: The variable rim height of 22-24 mm is designed to improve adaptability to various terrains. A lower rim height provides greater flexibility, allowing the wheel to better absorb bumps and bumps. This design choice improves comfort and control, as it helps the wheel adapt more effectively to the surface while still offering the resilience needed to handle difficult conditions. Innovative rim design: the KFX i28 incorporates an advanced rim design with a turret at the spoke insertion points. This feature strengthens the anchorage of the nipples and reduces the weight between them, which is critical to maintaining a low overall weight. The design is similar to the inter-spoke milling technology used in road wheels, which improves stiffness and control without adding unnecessary weight. This innovation ensures that the wheel remains light and responsive while offering superior strength and performance to ensure TOTAL CONTROL. PRS hub technology: at the heart of the KFX i28 is the new 72-tooth PRS ratchet hub, designed to provide instant engagement for optimal power transfer. This advanced hub technology improves responsiveness by significantly reducing lag during acceleration. Designed specifically for off-road use, the PRS hub is resistant to mud, sand and water, ensuring reliable performance in all conditions.
