Introduction

ICAN AERO 50 II Disc is a lightweight (only 1254 g), aerodynamic carbon wheelset designed for all-around road performance, flat-road speed, and triathlon racing. With optimized carbon layup, a wider 23mm inner rim, upgraded D91 hubs with 45T star ratchet, and premium Sapim CX-Ray spokes, it delivers responsive power transfer, enhanced stability, and long-lasting precision. Tubeless-ready for versatile setups and fewer flats—built for riders who demand speed, control, and efficiency.

Specification

1, Lighter, Stronger Rims 

Built for Aero Efficiency  
The AERO 50 II features a re-engineered carbon layup, optimizing both the fiber structure and layering sequence. This upgrade rims approximately 200g from the rim weight while preserving outstanding stiffness and durability, bringing the total wheelset weight down from 1456g to just 1254g. The result is a wheelset that delivers crisp power transfer and climbing agility, while maintaining the aerodynamic performance needed for flat-road speed and triathlon racing—ideal for all-around aero riding.

2, 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.

3, 23mm Inner Width for Enhanced Versatility
With a 23mm inner width and 28mm external profile, the AERO 50 II accommodates wider tires (28–32mm+), offering better grip, improved comfort, and enhanced stability. Whether you're tackling long rides, mixed terrain, or fast-paced flat routes, this wider design ensures a confident and compliant ride.

4, Upgraded D91 Hub System
Now equipped with the ICAN D91 hub, replacing the previous D01 model, the wheelset benefits from a 45T star ratchet system for rapid engagement and S&S steel bearings for smooth, reliable performance. The freehub body is smartly redesigned to remove excess material without affecting cassette compatibility, reducing total hub weight to just 280g and giving the entire wheelset a further edge in lightness and responsiveness.

5, Premium Spoke System
Built with Sapim CX-Ray aero spokes—renowned for their lightweight strength and aerodynamic profile—paired with Sapim Secure Lock nipples to maintain precise tension for long-lasting durability and performance.

6, Tubeless-Ready Versatility
Compatible with both clincher and tubeless setups, the 2-way tubeless-ready design gives riders the option for lower rolling resistance, fewer flats, and improved ride feel across various road conditions.
