For those riders who dare to discover the boundary of aerodynamics.
At Brisk, no detail is left uncompromised.
Eclipse is the result of pursuing every element to its absolute limit—no effort spared.
Its optimized sidewall profile is the result of extensive Computational Fluid Dynamics (CFD) simulation. This proprietary concave, Eclipse-inspired shape significantly mitigates crosswind effects and maintains superior aerodynamic stability at a 15-degree yaw angle, outperforming any other disc wheels.
The entire wheel is constructed as a true monocoque, integrating the hub directly into the sidewall while eliminating internal spokes and a traditional rim. This design not only removes excess weight, but also enhances structural integrity and ride quality. Laboratory testing measures its lateral stiffness at an exceptional 66 N/mm, once again setting an industry benchmark.
Featuring a fully tubeless-ready profile with a 27mm external and 23mm internal width, Eclipse is engineered to optimize both aerodynamics and comfort. Whether paired with 30mm or 28mm tires, the system maintains peak aerodynamic efficiency alongside a smooth, stable ride.
Leveraging BRISK’s core engineering, Eclipse brings unprecedented lightweight performance to the disc wheel category. Through monocoque construction and optimized carbon fiber layup, the finished weight is reduced to just 810g. The result: maximum aerodynamic advantage for time trial and triathlon bikes—without any weight penalty.
Visually, Eclipse is formed from six unpainted carbon fiber segments, seamlessly arranged into a perfect circle. Each segment is engineered to capture and reflect light at precise angles, creating a dynamic, restrained gleam that mirrors the wheel’s uncompromising performance and refined design.
Beyond the wheel itself, Eclipse is delivered as a complete, considered system.Each wheelset is supplied with 30 dedicated valve cover decals, housed in a precision storage case—ensuring long-term usability and visual consistency. Should additional sets be required in the future, replacements are provided at no cost. A carbon fiber tubeless valve, engineered for minimal weight and absolute sealing integrity, is also included—because every interface matters.
