CADEX, renowned for its high-performance cycling components, has unveiled the Max GXR WheelSystem and GXR Tyre, a meticulously engineered duo tailored for the demands of modern gravel racing. This integrated system emphasizes high-speed efficiency, control, and durability across diverse terrains.
Max GXR WheelSystem: Precision Engineering for Gravel Racing
The Max GXR WheelSystem is a comprehensive assembly of rim, spoke, and hub, crafted to deliver exceptional performance on gravel courses. Key features include:
-
Lightweight Carbon Construction: The 50mm deep carbon rims, combined with integrated CADEX Super Aero carbon spokes and a unified hub structure, result in a total system weight of just 1,320 grams, including tape and valves.
-
Aerodynamic Efficiency: Wind tunnel testing reveals a 4.61-watt reduction in drag compared to the CADEX AR 35, achieved through a 3.74-watt decrease in aerodynamic drag and a 0.87-watt reduction in rotational drag across various yaw angles.
-
Enhanced Durability: Wide 25mm hookless inner rim widths support larger-volume gravel tyres at lower pressures, expanding the contact patch to boost traction, control, and rolling efficiency across rough terrain. The rims feature Wide Guard technology with reinforced 5mm sidewalls engineered to withstand impacts and resist pinch flats, adding durability without the weight penalty. A precision-reinforced carbon layup places high-tensile fibers only where needed, while hidden titanium nipples and internal spoke tensioning maintain long-term structural integrity under repeated high-load conditions.
-
Improved Stiffness and Responsiveness: Dynamic Balanced Lacing balances spoke tension under pedaling and impact loads, delivering efficient power transfer, predictable handling, and immediate response. The CADEX R3-C60 hub’s 60-tooth ratchet system provides fast, precise engagement to maintain momentum through accelerations and terrain transitions. The Max GXR also increases rear-wheel transmission stiffness by 24.8% and improves transmission stiffness-to-weight by 19.9% compared to the CADEX AR 35.
GXR Tyre: Optimized for Gravel Performance
Complementing the wheel system, the GXR Tyre is engineered for high-speed performance across mixed gravel terrains. Its features include:
-
High-Volume Race Profile: A fast-rolling center tread and refined shoulder geometry work together to reduce rolling resistance while maintaining predictable traction and control in variable conditions.
-
170 TPI Casing: Provides a supple ride feel, enhancing comfort and responsiveness.
-
Puncture Protection: CADEX Race Shield+ puncture protection and X-Shield reinforced sidewall construction offer durability and reliability in demanding gravel conditions.
