CADEX MAX GXR WHEELSYSTEM
GRAVEL ATTACK
In gravel racing, the variables never stop. You have to balance efficiency, control and speed—and ride the razor-thin line between reward and risk. The new CADEX Max GXR WheelSystem gives you the upper hand. Deep 50mm aero rims, Super Aero carbon spokes, and our CADEX Max hub minimize drag and transmission loss, turning pedaling power into speed. System-built, race-ready, and just 1320g (1280g without valves and tape). Max GXR holds the line so you can push it.
SYSTEM-LEVEL AERO DESIGN
A fully integrated aerodynamic system where spokes, hub flange, and hub geometry all function as a single structure to reduce turbulence at the wheel center and improve airflow interaction across the wheel-tire interface. A 50mm rim profile paired with Super Aero carbon spokes delivers a measurable aerodynamic advantage across a broad range of yaw angles. Wind tunnel testing confirms a 3.74-watt reduction in aero drag and a 0.87-watt reduction in rotational drag, resulting in a total system gain of 4.61 watts versus the CADEX AR 35.
CADEX MAX GXR VS. CADEX AR 35 AERO PERFORMANCE:
STABILITY, CONTROL & EFFICIENCY
A 25mm inner rim width supports high-volume gravel tires at lower pressures, expanding the contact patch for improved traction, compliance, and control across rough terrain. Dynamic Balanced Lacing balances spoke tension under pedaling and impact loads to deliver efficient power transfer and predictable handling. The CADEX R3-C60 hub’s 60-tooth ratchet system provides fast, precise engagement to maintain momentum through accelerations and terrain transitions. Compared to CADEX AR 35, Max GXR increases rear-wheel transmission stiffness by 19.9% and improves transmission stiffness-to-weight by 18.8%.

RACE-READY DURABILITY
Reinforced 5mm Wide Guard sidewalls protect against rim strikes and pinch flats without requiring tire inserts. A precision-reinforced carbon layup places high-tensile fibers only where needed, improving impact resistance and torsional stiffness without excess material. Hidden titanium nipples maintain long-term structural integrity under repeated high-load conditions.
CADEX MAX GXR WHEELSYSTEM
GRAVEL ATTACK
Engineered for high-speed gravel racing, the CADEX Max GXR WheelSystem combines aerodynamic efficiency, system stiffness, and impact resistance in a fully integrated design. A deep 50mm rim profile, wide internal width, and reinforced sidewalls deliver speed and control across rough terrain, while the integrated Max hub and carbon spoke system optimize power transfer under load.
KEY FEATURES
• 50mm Aero Rim Profile – A deep 50mm rim profile maximizes aerodynamic efficiency, reducing drag for sustained high-speed performance in race conditions.
• Integrated Max Hub And Spoke Technology – A one-piece hub, flange, spoke, and rim structure forms a fully integrated system that minimizes drag, smooths airflow, and maximizes real-world efficiency at speed.
• 25mm Inner Width – Optimized inner width supports higher gravel tire volumes at lower pressures, increasing the contact patch for improved traction, compliance, and control.
• Wide Guard Rim Protection – Reinforced 5mm sidewalls defend against rim strikes and pinch flats, eliminating the need for tire inserts and unnecessary weight.
• Precision Reinforced Carbon Layup – High-tensile fibers are strategically placed only where needed to create a strong, torsionally stiff structure while minimizing overall weight.
• CADEX Super Aero Carbon Spokes – High-tensile integrated carbon spokes with hidden nipples and independent internal tensioning minimize lateral flex for efficient acceleration and responsive climbing.
• Dynamic Balanced Lacing (DBL) – A wider bracing angle and balanced spoke tension under pedaling load result in a stiffer wheel with outstanding power transfer and handling precision.
• CADEX R3-C60 Aero Hub – An aerodynamic hub design with a 60-tooth ratchet delivers instant engagement for immediate power transfer over rough, technical terrain.
• Ratchet Wave Spring System – A wave spring design ensures consistent, balanced ratchet engagement, resulting in smoother operation and improved rolling efficiency.
• CADEX Hookless Rim Technology – An optimized carbon layup and hookless rim design reduce weight while improving durability and tire stability under high-speed loads.
• In-Mold Carbon Graphics – CADEX logos are integrated directly into the carbon surface for a clean, premium finish with no decals, no added weight, and no risk of fading.

CADEX TECHNOLOGIES
CADEX CERAMIC BEARINGS
Durabl ceramic bearings further increase hub rolling efficiency with lower rolling resistance and 1.5x smoother action than steel bearings.
CADEX HOOKLESS RIM TECHNOLOGY
A broad inner rim width and durable continuous carbon fiber structure on the rim walls create a rounder tire shape for superior grip and handling plus added sidewall support for cornering, all without compromising on weight.
CADEX PRECISION REINFORCED LAY-UP
High-tensile-strength carbon fiber is strategically placed only where needed, creating a strong, stiff structure at minimal weight.
CADEX R3-C60 AERO HUB
Precision machined 60 tooth ratchet hub with CADEX Ratchet Wave Spring offers ultrafast engagement, reduces aerodynamic loss and virtually eliminates bearing load as ultra-smooth, low-rolling resistance CADEX ceramic bearings further reduce watt loss.
CADEX SUPER AERO CARBON SPOKES
High tensile-strength aero carbon spokes minimize lateral flex for more efficient acceleration and climbing. The spokes feature a purpose designed shape that combines aero efficiency with superior stability in shifting winds, all at the lightest weight possible.
CUSTOM-TUNED DYNAMIC BALANCED LACING (DBL) TECHNOLOGY
Dynamic Balanced Lacing technology sets spokes at a wider bracing angle and evens out spoke tension under pedaling force. This helps produce a stiffer, more efficient wheel with outstanding power transfer.
INTEGRATED HUB DESIGN
One-piece aero hub and spoke design, where CADEX Super Aero carbon spokes are seamlessly bonded straight into the aero hub flange, forming a one-piece structure with the hub. This integrated configuration places the nipples inside the rim, while still ensuring independent tension tuneability.
IN-MOLD CARBON SURFACE GRAPHIC TECHNOLOGY
Advanced carbon molding technology allows fine rim surface finishing treatment directly within the mold, eliminating the need for additional carbon treatment or decals.
