Cadex Aero Disc Tubeless Centerlock Disc Brake Carbon Rear Road Wheel

There is no greater proving ground for an aero wheel than an Ironman triathlon. It’s 180km, just you against the wind. No drafting, no hiding. Chosen by some of the world’s fastest pros including Olympic Ironman and Sub7 champion Kristian Blummenfelt, the all-new Aero Disc WheelSystem is the fastest wheel ever created by CADEX. The superlight and stiff carbon rims have an asymmetrical design shaped by exhaustive wind tunnel testing and data. The all-new R3-C40 aero hub with ceramic bearings reduces friction by up to 30 per cent over the previous generation. The 22.4mm wide hookless rims create a seamless integration between the rim and tubeless tire for improved rolling resistance, increased sidewall support, and better cornering grip. It all adds up to best-in-class aerodynamics, unbeatable efficiency, and total control in all conditions.

Key Features:

• Super Aero Rim Shape features wider external dimensions for maximum aerodynamic advantage in the most common wind directions when paired with CADEX Aero Tubeless tyres
• Ultralight 18k carbon composite creates a stiff and stable wheel structure with class-leading torsional and lateral stiffness.
• Precision machined CADEX R3-C40 aero hub significantly reduces bearing load, and CADEX ceramic bearings produce 1.5 times less friction than steel bearings.
• A 22.4mm inner rim width and durable continuous carbon fibre structure create a rounder tire shape for superior grip and handling as well as added sidewall support when cornering, all without compromising on weight.
• Increased rim bead width of up to 3mm per side enhances rim bead stiffness, offering better support for tires when cornering and improving air transition from the tire sidewall to the wheel for improved aerodynamics.
• A unique asymmetrical disc profile augments structural balance.

Asymmetrical Disc Profile
Unique asymmetrical disc profile augments structural balance.

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.

Optimized Composite Engineering
Ultralight 18k carbon composite creates a stiff and stable wheel structure with class-leading torsional and lateral stiffness.

CADEX R3-C40 Aero Hub
Aero optimized hub features 3rd generation CADEX Low-Friction internals with CADEX ceramic bearings and 40-tooth ratchet engagement.
