We appreciate your question regarding the indented surface on the top of the bars.
The indentation on the top of the handlebar is designed to enhance ergonomics and improve aerodynamics. This shape provides a more comfortable hand position during long rides, reduces pressure on your palms, and allows for better grip. Additionally, it helps streamline airflow for improved performance, making it an excellent choice for competitive and recreational cycling alike.
