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.

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 stiff-ness-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 alloy nipples maintain long-term structural integrity under repeated high-load conditions.

Technologies

CADEX Ceramic Bearings

Durable, ultra-hard 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 create a rounder tire shape for superior grip and handling plus added sidewall support for cornering, all without compromising on weight.

CADEX Precision Reinforced Layup

CADEX precision reinforced layup places high tensile strength carbon fiber only where needed, creating a strong, stiff structure at minimal weight.

Custom-Tuned DBL Technology

Dynamic Balanced Lacing technology sets spokes at a wider bracing angle and for the same tension level under pedaling force, producing 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 hides the nipples into the rim, while ensuring independent tension tuneability.

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.

In-mold Carbon Surface Graphic Technology

Advanced carbon molding technology allows fine rim surface finishing treatment directly within the mold, elminating the need for additional carbon treatment or decals.

CADEX Super Aero Carbon Spokes

Ultra-lightweight high tensile-strength CADEX aero carbon spokes minimize lateral flex for more efficient acceleration and climbing and feature a purpose designed aero shape offering class-leading aerodynamic characteristics as well as superior stability in shifting winds.
