Abstract
The invention disclosed herein is a light weight, mountain bicycle competition wheel rim. The invention provides improved fatigue and impact resistance compared to prior art designs. The invention makes maximum use of advanced, high strength aluminum alloy materials, improving its stiffness-to-weight and strength-to-weight ratios. The superior structural performance of the invention is provided by a unique truss type section geometry that efficiently utilizes the material to maximize bending and torsional stiffness and strength while minimizing weight.
