The Reserve 32 Zipp ZR1 ST Carbon Front Wheel is the definition of lightweight precision — a wheel built for climbers, endurance riders, and anyone who prizes responsive handling and stability on demanding terrain. Designed around a shallow 32 mm rim profile, it offers rapid acceleration and intuitive steering feel, making it ideal for steep ascents, switchback descents, and long rides where control matters as much as speed.

Reserve’s proprietary carbon lay-up gives this wheel an exceptional balance of stiffness and comfort. Each rim is hand-laid and tuned for uniform spoke tension, ensuring consistent strength and reliability mile after mile. The 21 mm internal width is optimized for 25–30 mm road tires, creating a wide contact patch that increases grip and smooths road chatter while maintaining aerodynamic cleanliness. Whether running tubeless or traditional clinchers, the hookless, tubeless-ready design allows easy setup and lower pressures for reduced rolling resistance and a more compliant ride.

At the center of the build, Zipp’s ZR1 ST hub provides effortless spin and reliability. Developed in Germany and featuring precision-sealed cartridge bearings, the hub runs smooth through thousands of kilometers of real-world use. The lightweight shell and refined flange geometry create balanced spoke angles that promote stiffness and responsive handling. The result is a front wheel that feels alive — tracking with accuracy through fast descents and responding instantly to every steering input.

Every Reserve 32 ZR1 ST Front Wheel is hand-built using Sapim CX-Ray bladed spokes for maximum strength and low weight, with perfect tension balance ensured by Reserve’s experienced builders. It’s not just a climbing wheel — it’s a confidence wheel: agile on ascents, stable in gusts, and unfazed by long technical descents. From mountain roads to rolling race courses, it brings the unmistakable Reserve feel — efficient, composed, and ready for whatever lies ahead.
