The system combines two modules — a frame bag and a top tube bag — that work together to smooth airflow and eliminate gaps between the frame and stem. The result: less resistance, more speed, and proven aerodynamic gains on every bike tested.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast, flush, one-handed access\u003c\/strong\u003e - The Aero System’s top tube module opens instantly with a magnetic TPU flap, while the frame module uses a low-profile zip for secure, streamlined storage.
