The Specialized Roval Alpinist CLX III 700c Wheel is an ultralight climbing wheel system engineered to deliver maximum acceleration, efficiency, and responsiveness on steep road gradients. Designed for riders who demand elite-level performance when every gram matters, this wheelset represents the pinnacle of modern lightweight road engineering, where climbing speed and ride feel are the top priorities. Weighing just 1,131 grams complete with valves and tape, the Alpinist CLX III achieves a significant reduction in rotating mass compared to the previous generation. A newly developed lightweight hub system combined with Roval Aero Composite Spokes by ARRIS removes over 100 grams from the system while increasing strength by 20% over comparable steel spokes. This results in a wheel that is not only exceptionally light, but also highly durable and race-ready for real-world demands. At the core of its performance is a refined hub and rim system built around DT Swiss 180 EXP internals with 36-tooth engagement, delivering fast, precise power transfer with proven long-term reliability. The hooked rim design ensures secure tire retention, easier installation, and tubeless compatibility up to 110 psi, while remaining optimized for 28mm tires and compatible with a 24-38mm range for versatile road use.
