Reserve’s engineering team has decades of experience in composites engineering, aerodynamics, and high-performance bicycle design. We know what strength and impact resistance means for a mountain bike and a mountain bike wheel, and have spent countless hours seeing how CFD and wind tunnel testing translate into real world road riding. We approach every rim we make with a specific problem to solve, and we believe the solutions speak for themselves—in the wind tunnel, on the trail, and in the breakaway. All of our rims are designed for tubeless tires—that doesn’t mean you can’t stick a tube in there, just that you don’t need to.
