Description
Go Farther, Faster
The Apidura Aero Bolt-On Top Tube Module is a strapless, aero-optimized top tube pack that integrates seamlessly on your bike to make you faster. This is a performance-oriented solution for competitive gravel racers, developed through rigorous Computational Fluid Dynamics (CFD) analysis to smooth airflow behind the stem and improve aerodynamic efficiency.
Combiningwith the Aero Frame Module createsan average 5 watt saving at race speed, validated through wind tunnel testing and race-proven at the highest level, showing a benefit on every bike Apidura have tested.
Features:
- Works with Frame Module to improve aerodynamics
- Transfer panel technology reduces drag
- One-handed fast entry for 0.4L model
- Waterproof, zipped closure for 0.8L model
- Ultralight Hexagrid construction
Specs:
- System Aero Benefit: 5 watt average saving.
- Weight: 95/120g
- Capacity: 0.4L/0.8L
- Storage: Single main compartment.
- Closure: Fast entry magnetic closure or Full length waterproof zipper
- Attachment: Two M5 hex-headed bolts anchor module to top tube mounts. Center channel in base flexes around mounting points, pulling module flush against top tube for a gap-free fit. Elastic tensioner contours to the stem and draws Transfer Panels inward for aerodynamic efficiency.
- Reinforced Structure: Full-length carbon fiber reinforcement ensures a rigid, strap-free fit to the top tube. Internal HDPE thermoplastic frame.
- Waterproofing: Seam welded — bespoke materials and RF welding create watertight seams. Note: while materials are fully waterproof, the magnetic closure is not.
- Visibility: Reflective graphics.
