An aerodynamically optimized top tube bag that attaches without straps, integrates seamlessly with your bike, and makes you faster.
The Aero Bolt-On Top Tube Pack is a performance-oriented solution for ambitious gravel racers. It was developed using extensive CFD (Computational Fluid Dynamics) analysis to optimize airflow behind the stem and boost aerodynamic efficiency.
When paired with the Aero Frame Pack, it delivers an average saving of 5 watts at race speeds. This has been validated in the wind tunnel and proven in top-level racing—an advantage observed across every bike tested by Apidura.
- Improves aerodynamics when paired with the frame pack
- "Transfer Panel" technology reduces drag
- Quick, one-handed access to the top tube pack
- Ultralight Hexagrid construction
Materials & Technology:
-
Hexagrid: An ultralight, high-strength nylon mesh laminated with TPU to create a material that is both minimalist and structured. Free from PFAS and PFCs.
-
HDPE: High-strength, rigid reinforcement plate with good shape retention to prevent deformation.
-
Aero-optimized: Actively improves the aerodynamic efficiency of both bike and rider.
-
Ultralight: Minimalist design and lightweight materials for an optimal weight-to-performance ratio.
Product information:
- Aero system benefit: Average saving of 5 watts
- Weight: 95 g
- Volume: 0.4 l
- Storage layout: Single main compartment
- Closure system: Magnetic closure for quick access
- Mounting system:
- Two M5 hex bolts anchor the module to the top tube mounting points
- A central channel in the base flexibly adapts to the mounting points and pulls the module flush against the top tube – ensuring a seamless fit
- An elastic tensioner hugs the stem and pulls the sidewalls inward – for aerodynamic efficiency without creating gaps
- Reinforced structure:
- Continuous carbon fiber reinforcement ensures a stable fit on the top tube without the need for straps
- Internal thermoplastic HDPE frame
- Waterproofing:
- Welded seams: Special materials and high-frequency welding ensure waterproof seams
- Note: While the materials themselves are completely waterproof, this does not apply to the magnetic closure
- Visibility: Reflective graphics
Care & Maintenance:
- Spot cleaning only
- Stains can be treated locally with concentrated dish soap
- Avoid rubbing
