New CADEX Aero Cotton Tire Blends Aerodynamic Integration, Low Rolling Resistance, and Exceptional Ride Feel

May 8, 2025

Innovative aero shaping, 320 TPI Cotton Race Casing and RR-S2 silica compound deliver speed, control and efficiency

May 8th, 2025 /ENDURANCE SPORTSWIRE/ — CADEX, a global leader in high-performance cycling components, announced the launch of the CADEX Aero Cotton, a premium road tire for elite racers, time trialists and triathletes. Engineered for maximum aerodynamic efficiency, ultra-low rolling resistance, and road-smoothing compliance, the Aero Cotton delivers top-tier performance where speed and precision matter most.

“The Aero Cotton brings together the elements that matter most for pro riders—low rolling resistance, confident handling, and aero performance,” said Jeff Schneider, Global Head of Product for CADEX. “With a refined hookless profile, high-TPI cotton casing, and our latest compound technology, it’s built for real-world race conditions.”

Already proven at the highest level of competition, the CADEX Aero Cotton has been ridden by Team Jayco AlUla at the Tour of Flanders, one of the most challenging events in professional cycling, where rough cobblestones, variable conditions, and intense race speeds demand pro-level performance and reliability.

Designed to work seamlessly with CADEX hookless rims, the Aero Cotton features a taller sidewall that creates a smooth, oval shape for optimal aero performance. This integration reduces drag and enhances airflow across the tire-rim interface, helping save watts at high speeds.

At the core of its ride quality is the Lightweight 320 TPI Cotton Race Casing, which delivers superior suppleness, smooth compliance, and pinpoint handling while keeping weight to a minimum. The tire’s RR-S2 silica compound further boosts performance, reducing rolling resistance by 30% compared to the previous compounds.

A smooth center tread supports high-speed efficiency, while the micro-textured shoulder improves grip and water dispersion for confident cornering in all conditions. And for added reliability, Race Shield puncture protection employs a lightweight Kevlar® center patch to guard against cuts and flats without adding unnecessary weight.

The Aero Cotton also features a hybrid carbon-Zylon bead for a secure, airtight fit on hookless rims—ideal for riders pushing the limits of performance.

The CADEX Aero Cotton tire will be available through select retailers and online in key markets worldwide.
