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.

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.

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.

Hookless Rim Design

Provides the best flow transition from the tyre to the sidewall of the rim, resulting in reduced aerodynamic loss when compared to standard hook bead rims, and featuring a continuous carbon fibre structure enhancing overall durability.

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.

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.

Custom-Tuned DBL Technology

Dynamic Balanced Lacing ensures spokes are set for optimal tension when under dynamic pedalling force versus when static, resulting in superior transmission stiffness and efficiency.

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.

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 Wide Guard Rim Protection

Reinforced 5mm sidewalls defend against rim strikes and pinch flats, eliminating the need for tire inserts and unnecessary 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.
