Introduction The AERO II Disc is the second-generation product. While retaining the 23mm internal width, the rim has been upgraded to a U/V Rim Shape. It combines U-shape stability with V-shape aerodynamics for lower drag, better stiffness, and smoother handling across all terrains. Changes have also been made to the brand logo design. Features Upgraded Ultra-Lightweight Performance At just 1178g per pair, the ICAN AERO 40Ⅱ Disc features a refined carbon layup that cuts 204g off the original weight without compromising stiffness or durability. Among the lightest aero disc wheels—built for racers and climbers chasing peak efficiency. Only 1253g AERO 50 II disc wheels, optimized carbon layup reduces weight while preserving stiffness and durability, delivering climbing agility and aero efficiency for all-around and triathlon use. Optimized U/V Rim Profile for Aerodynamics and Control The upgraded U/V rim profile combines the aerodynamic stability of a U-shape with the wind-cutting efficiency of a V-shape, delivering reduced drag and better performance in crosswinds. This design also enhances lateral stiffness for improved power transfer during sprints and climbs, while offering smoother tire-to-rim transitions for better handling, comfort, and versatility across varied terrains. Enhanced 23mm Inner Width Featuring a wider 23mm internal rim, this update accommodates wider tires (28–32mm+) for better grip, improved comfort, and increased stability—ideal for long-distance rides, all-road conditions, and modern wide-tire setups Enhanced Hub Design for Superior Performance The AERO II disc wheels feature the upgraded ICAN D91 hub, replacing the previous D01 model. It adopts the popular 45T star ratchet system for faster engagement and is equipped with premium S&S steel bearings for improved durability and smoothness. The freehub body has been cleverly optimized, removing excess material without affecting cassette compatibility, reducing the total hub weight to just 280g. This smart redesign contributes to the overall lighter and more efficient wheelset performance. Premium Sapim CX-Ray Spokes Built with Sapim CX-Ray aero spokes and Sapim Secure Lock nipples for unmatched strength, tension retention, and long-lasting performance—delivering smooth, stable rides with every revolution. Tubeless-Compatible Versatility Compatible with both tubeless and clincher tires, this 2-way tubeless-ready design offers lower rolling resistance, fewer flats, and the flexibility to adapt to your preferred road setup. Ideal for aero road bikes and lightweight climbing builds. UCI Certification AERO 40 II disc wheels and AERO 50 II disc wheels are certified and approved by the Union Cycliste Internationale (UCI), which governs internationalbicycle racing. Only products that pass rigorous testing receive this certification, allowing them to be used in UCI-sanctioned road races.
