Aero Top Tube Kase (ATTK) IC

Streamlined Storage. Optimized Aerodynamics.
The Aero Top Tube Kase (ATTK) IC is engineered to enhance your bike’s aerodynamic performance while providing a practical storage solution for race-day essentials. Its sleek, low-profile design minimizes drag and integrates cleanly with your bike’s top tube for a refined look and improved airflow.

A uniquely designed shell allows internal cable routing directly through the top tube, maintaining a clutter-free setup. Installation is simple — use your bike’s top tube braze-ons or the included Frame Protection Strips (FPS) for secure mounting on non-braze-on frames.
