Developed and tested using Turbulent Aero technology, the 42|49 is designed for everything you do, providing all-day capability with aerodynamic sensibilities. Raced at events as varied as the Paris-Roubaix and the Giro D’Italia, the 42|49 wheels have a lifetime warranty supported by a no-fault crash replacement. And in keeping with Reserve workmanlike ways, you’ll find external nipples, standard spokes, no tire limitations with a semi-hooked design and no rider weight limits. Shown also with optional team graphics, available by request.

Wind Tunnel Tested

The life of a wheelset like the new Reserve 42|49 begins with Computational Fluid Dynamics (CFD), with the goal of maximizing aerodynamics while enhancing stability. Reserve’s exclusive wind-tunnel testing then provides data that is focused on simulating real-world air flow, allowing us to confirm performance targets in a sterile and controlled environment. In the end, Reserve has created one of the most stable and aerodynamic wheelsets to date.

Strong AND Light

Optimizing the strength and weight of our rims in an exhaustive effort and it all starts at our California composites lab located in Santa Cruz. Not only do we work to develop the carbon fiber layup, but we have developed a proprietary test protocol to mimic real-world impacts and spoke pull outs on wheels. As a result, we are able to define the exact fiber orientation for each rim model to maximize stiffness and strength.

Lifetime support

We know how annoying it can be to miss a day of riding, especially when it’s because of an equipment problem. Reserve was the first company to offer a lifetime warranty on carbon wheels, and we extend this warranty to any and every Reserve product, including the 42|49. So ride with confidence and know that if there is a problem, we will be there for you.
