Bicycle Sprocket Diagram - Technical Illustration for Mechanics & Designers #3389500 (License: Personal Use)

This black-and-white line illustration depicts a single-speed bicycle sprocket, featuring evenly spaced teeth around the perimeter and a central circular hub with a rectangular keyway slot to prevent rotational slippage on the axle. The clean, precise linework emphasizes functional geometry rather than realism, making it suitable for technical documentation or instructional material. A small dot near the bottom may indicate a reference mark or manufacturing feature.

Used in mechanical engineering diagrams, bicycle repair manuals, parts catalogs, and educational content about drivetrain systems; matches user intent for understanding sprocket structure, identifying components, or creating CAD references.
