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.... Read More
