The Reserve 50 Zipp ZR1 ST Carbon Front Wheel represents the sweet spot between aerodynamic efficiency and everyday stability. With its 50 mm rim depth, it’s engineered for riders who demand speed on open roads but still need precise control when crosswinds pick up. It’s the front wheel for racers, fast endurance riders, and anyone who wants uncompromising aero performance without sacrificing predictable handling.

Reserve’s proprietary carbon lay-up gives the 50 mm rim its signature feel — stiff under power yet composed across uneven surfaces. The aerodynamic profile has been sculpted to manage turbulent air flow smoothly around the tire and rim, maintaining balance and control in real-world conditions, not just in the tunnel. The 21 mm internal width pairs perfectly with 25–30 mm tires, creating a stable, aerodynamic transition that improves traction and reduces rolling resistance. It’s a versatile setup built for modern tire widths and the speed-focused rider who values control as much as outright performance.

At its core, Zipp’s ZR1 ST hub brings refined precision to every rotation. Designed in Germany and built with fully sealed cartridge bearings, it delivers smooth, low-drag rolling for thousands of hard miles. The lightweight alloy shell minimizes mass at the hub’s center, improving responsiveness and steering feedback. Balanced flange geometry promotes even spoke tension, translating to stiffness that you’ll feel instantly when cornering or descending at high speed. It’s a hub designed to stay silent, spin effortlessly, and perform long after the race ends.

Every Reserve 50 front wheel is hand-built with Sapim CX-Ray bladed spokes and perfectly tensioned by Reserve’s experienced builders for strength, longevity, and reliability. The tubeless-ready, hookless rim bed simplifies setup while improving tire fit, letting you run lower pressures for better grip and ride quality. The result is a wheel that’s light enough for climbing days and aerodynamic enough for hammering into the wind — an all-conditions performer that carries the unmistakable Reserve character: precise, fast, and composed. Whether it’s a solo breakaway, a fast descent, or a headwind grind, the Reserve 50 ZR1 ST Front Wheel is engineered to keep you in control while you push the pace.
