1. 23mm Internal Width – Optimized for Modern Road Tires, Balancing Climbing Stability & Aerodynamics

Boasting a 23mm internal width, the R23-28 follows the industry-wide shift toward wider road rims. Paired with 25–28mm road tires, it forms a seamless aerodynamic profile and drastically boosts riding stability. On long endurance climbs or sprint breakaways alike, it delivers a smoother ride, superior corner traction, and more efficient power transfer from your pedals.

2. Asymmetric Rim Profile – Balanced Stiffness for Direct Climbing Power Transfer

Built with an asymmetric rim profile, the R23-28 achieves balanced lateral stiffness on both sides for unobstructed power delivery. This design drastically reduces rim flex during aggressive out-of-the-saddle climbing, enhances long-term durability, and resists wheel truing loss after thousands of kilometers. It maintains razor-sharp handling responsiveness without sacrificing weight savings.

3. Class-Leading Lightweight – Complete Wheelsets Under 809g

At just 245 grams apiece, the Flyweight rim ranks among the lightest options within its climbing rim category, delivering a decisive competitive edge for weight-conscious climbers. When built with Extralite hubs and Berd carbon spokes, the full wheelset weighs in at under 809 grams. It enables snappier acceleration, effortless steep climbing, and drastically cuts fatigue on lengthy ascents.

4.Fully Customizable Wheel Builds – Tailor Your Setup to Match Your Needs

We offer a wide selection of premium hub options including DT Swiss, ChrisKing, H-woks, Extralite and more. Freehub bodies cover all mainstream standards: Shimano 10/11-speed, SRAM XDR, Campagnolo and Micro Spline.
