Introduction This 63mm deep, 25mm internal width road disc brake wheelset is purpose-built for flat-out sprints and triathlon/TT racing. The optimized carbon layup balances aerodynamic stiffness with low weight, while the wide inner rim pairs perfectly with wider tires to significantly reduce rolling resistance and improve crosswind stability. The upgraded D91 hubs feature a 45T ratchet for instant, lag-free engagement; the titanium freehub body resists corrosion and wear, and combined with Sapim CX-Ray bladed spokes, delivers exceptional drivetrain efficiency and silky-smooth cruising. This is a high-performance wheelset engineered for pure speed and stability. Features Upgraded Ultra-Lightweight Performance Only 1424g AERO 63 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 25mm Inner Width Featuring a wider 25mm internal rim, this update accommodates wider tires (28–50mm+) 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. It adopts the popular 45T 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.
