Design and Build
The Proxima 50 Team Edition features a 50mm deep carbon rim with an internal width of 23mm and an external width of 30mm. The rims are tubeless-ready, allowing for compatibility with wider tires, enhancing comfort and grip. Each wheel is laced with 24 Sapim CX-Ray spokes in a two-cross pattern, contributing to the wheel’s stiffness and responsiveness. The hubs are equipped with ceramic bearings, which reduce friction and improve smoothness. (bike-x.de)
Performance
In testing, the Proxima 50 Team Edition demonstrated high lateral stiffness, providing precise handling and efficient power transfer. The wheels maintained stability even in windy conditions, thanks to their aerodynamic profile. However, the 50mm rim depth may not be ideal for riders seeking maximum acceleration, as the wheels are slightly heavier compared to lower-profile options. (bike-x.de)

The Ursus Proxima 50 Team Edition wheelset offers a blend of aerodynamics, stiffness, and reliability, making it suitable for competitive road cycling. Its design aligns with the needs of professional riders, as evidenced by its use in the WorldTour. While it may not be the lightest option available, its performance characteristics make it a compelling choice for those seeking a high-quality wheelset.
