The specified assembly represents a component, typically utilized in bicycle construction, characterized by an elliptical design principle applied to its supporting structure. This structure, often referred to as the stem, features a primarily dark (black) finish complemented by silver-toned accents. Critical to its function is the angular relationship between key elements, defined by measurements of 90 and 84 degrees. A diameter of 28.6 millimeters further constrains its physical dimensions, influencing compatibility with corresponding bicycle parts. As an example, this could describe a handlebar stem where the clamping area that attaches to the steer tube is ovalized for aerodynamic reasons, is primarily black with silver highlights, and the angle of the stem is either 90 or 84 degrees and the steer tube diameter is 28.6mm (1 1/8″).
The integration of this component is significant due to its potential to enhance both the aesthetic appeal and functional performance of a bicycle. The geometric configuration, particularly the precisely defined angles, contributes to optimized rider ergonomics and control. The material selection and finish contribute to durability and resistance to environmental factors. Historically, advancements in bicycle component design have focused on achieving an improved balance between weight, strength, and aerodynamic efficiency; this particular element reflects a continued pursuit of such improvements.
