CADEX Aero 4 Spoke Tubeless Disc Rear Wheel - 28" | Carbon | Hookless | Centerlock - 12x142mm - Shimano HG / SRAM XDR

From the strong winds in Kona to training rides in extreme conditions, the CADEX Aero 4-Spoke combines proven aerodynamics with confident handling and control. Featuring super-light and stiff CADEX 1K carbon rims shaped by extensive wind tunnel testing and data, a CADEX Low Friction R3-C40 Aero hub with ceramic bearings, and a 22.4 mm inner rim width, it offers best-in-class aerodynamics, unbeatable efficiency, and complete control in all conditions.

CADEX 1K Carbon Weave

A high-quality carbon fiber weave with bundles of 1000 filaments woven in two directions for a smoother surface and lower weight.

ceramic bearings

Durable, ultra-hard CADEX ceramic bearings run 1.5 times smoother than steel ball bearings, improving the overall efficiency of the wheel.

Hookless rim design

Optimized airflow from the tires to the rim improves aerodynamics and rim stability thanks to continuous carbon fiber flow compared to a hook rim.

CADEX Precision Reinforcement Layer

CADEX Precision Reinforcement places high-strength carbon fibers only where they are needed, creating a strong, stiff structure with minimal weight.

CADEX R3-C40 Aero Hub

The precision-engineered CADEX R3-C40 Aero hub significantly reduces bearing load, and CADEX ceramic bearings generate 1.5 times less friction than steel bearings.

Features of the CADEX Aero 4 Spoke tubeless disc rear wheel

• Special shape of the aero rim offers wider external dimensions for maximum aerodynamic benefits in the most common wind directions.
• Slim and ultra-lightweight 1K carbon provides a stiff and stable wheel structure with first-class torsional and lateral stiffness.
• Precision-machined CADEX R3-C40 aero hub significantly reduces bearing load, and CADEX ceramic bearings generate 1.5 times less friction than steel bearings.
• Increased rim bead width of up to 3mm per side improves rim stiffness, provides better tire grip when cornering, and improves air transition from the tire sidewall to the wheel for improved aerodynamics.
• A 22.4 mm inner rim width and a robust continuous carbon structure create a rounder tire shape that provides superior grip and handling as well as additional sidewall support when cornering, all without compromising weight.
