Profile Design ATTK IC Top-Tube Storage Case, Black One Size — Low-Profile Aero with Frame Protection

The Profile Design ATTK IC Storage Case w/ FPS is an aerodynamic top-tube storage solution that keeps tools, energy bars and small essentials secure while maintaining a low, race-ready profile.

The Aero Top Tube Kase (ATTK IC) with Frame Protection Strip (FPS) is built to reduce drag and provide tidy, accessible storage on bikes with compatible top-tube braze-ons. Its contoured shell routes cables through the case to preserve clean lines, and it mounts quickly either to braze-ons or by using Velcro straps (sold separately). Adding the FPS gives extra protection and stability when fastening with cable ties.

How does this case improve aerodynamics on my bike?

The ATTK IC is shaped to follow the top tube and minimize protrusions that cause wind resistance. Routing cables through the case rather than around it maintains smoother airflow, which helps preserve your bike’s aero profile during rides.

• Contoured shell aligns with the top tube to reduce drag.
• Internal routing for brake/shift cables keeps lines clean.
• Low-profile mount options limit extra bulk on the frame.

What mounting methods are available and how secure is the fit?

The case installs directly to bikes with compatible top-tube braze-ons for a fixed, sturdy attachment. If your frame lacks braze-ons, you can use Velcro straps sold separately; the included FPS makes cable-tie installation more reliable when additional fastening is needed.

• Mounts to top-tube braze-ons for tool-free attachment.
• Compatible with Velcro strap mounting (straps not included).
• Frame Protection Strip (FPS) improves grip and prevents abrasion when using ties.

What will fit inside the ATTK IC and how is accessibility?

The interior holds compact essentials—multi-tools, CO2 cartridges, spare tubes, or nutrition—organized without shifting during rides. The top-opening design provides quick access so you can retrieve items on the go without dismounting in many situations.

• Sized for small cycling essentials and ride-day necessities.
• Secure internal shape keeps items in place while riding.
• Top access allows fast retrieval during breaks or stops.

Does the Frame Protection Strip (FPS) add value?

The FPS adds a layer of protection between the case and your frame, reducing the chance of paint wear and increasing mounting stability when cable ties are used. It’s a practical addition for riders who want a safer, longer-lasting installation without modifying the frame.

• Protects frame finish from abrasion under the case.
• Improves grip and prevents shifting when using ties.
• Easy to add during initial installation for extra security.

Who is this for? The Profile Design ATTK IC Storage Case w/ FPS is for road and triathlon cyclists who want a sleek, aerodynamic storage option for small essentials. It’s especially useful for riders with top-tube braze-ons who value tidy cable management and a low-profile setup, and for those who prefer the option of secure cable-tie or Velcro mounting with frame protection. If you need robust, race-oriented storage that complements aero frame geometry, this case is a practical addition to your kit.
