Miche expands its high-performance lineup with the new Graff Aero 48: carbon wheels engineered for top-level gravel racing. The result of a rigorous, detail-focused development process, the Graff Aero 48 were created in close collaboration with some of the best gravel specialists. Among them, Traka and Unbound winner Ivar Slik played an active role, bringing real-world racing experience into the project.The outcome? A wheelset that pushes the boundaries of performance, reliability, and control — across all types of terrain. Every aspect is designed for riders with a racing mindset: athletes for whom every second, every turn, every watt counts.
Hookless Rim
The UD carbon rim features a 48mm depth and a 27mm internal width with a TSS hookless profile, made specifically for tubeless-ready tires ranging from 35mm to 60mm. The optimized rim shape, paired with double-butted aero spokes, delivers superior aerodynamic efficiency and ride stability — even at high speeds and on rough terrain.
Miche's Hubs
CX-Graff hubs are fitted with Miche’s high-smoothness bearings for maximum fluidity and long-term durability. The 24-spoke lacing pattern (12+12) is engineered to optimize tension distribution and load absorption, tailored to the needs of competitive gravel racing.
